Diagram Ref No 7A

What This Product Does:

• In a uniball (spherical bearing) design, the elastic rubber center is replaced (or augmented) with a metal bearing that allows rotation and articulation but eliminates flex / deflection.
  
• This gives a much more direct mechanical interface—engine motion under load is significantly reduced compared to rubber alone.
• Because the spherical joint has very low compliance, the mount becomes much more rigid in the direction of torque / twist (longitudinal / rotational direction) while still permitting the required articulation in other axes.
• This variant is often preferred for track, clubsport, or dedicated performance cars where precision and rigidity matter more than comfort.
  
  

Symptoms Of Worn Or Failing Engine Mounts:

• Excessive Engine Movement - When accelerating, decelerating, or cornering, you may notice the engine rocking or shifting more than normal.
  
• Clunking or Knocking Noises - A distinct thud, clunk, or metal-on-metal noise when shifting gears or during abrupt acceleration/deceleration indicates the mounts are no longer isolating movement properly.
  
• Vibration in the Cabin or Steering Wheel - As the mount deteriorates, it loses its ability to absorb vibration from the engine.
  
• Poor Gearshift Precision - Engine movement causes slight misalignment in the drivetrain, which can result in imprecise or “notchy” gear changes.
  
• Unstable Handling or Driveline Feel - Excessive engine movement shifts the vehicle’s center of gravity and can create a “loose” or unsettled feeling during hard cornering or braking.
  
• Visible Wear or Fluid Leaks - The original Porsche mounts are hydraulic on many 964/993 models; when they leak fluid or collapse, engine support is compromised.
  
• Rattling or Exhaust Misalignment - Worn mounts allow the engine to sit lower or twist, which can cause contact between the exhaust system and underbody components, leading to rattling or vibration noises.
  
  

Why This Upgrade Version Matters:

• Maximum Rigidity / Minimal Deflection — virtually no unwanted movement, giving optimal drivetrain alignment and responsiveness.
  
• Sharper Response & Consistency — throttle, shifts, and engine behavior are more direct because the engine is “locked down.”
  
• Better Repeatability — especially in motorsport, lap after lap the behavior remains consistent.
  
• High Load Handling — in high torque / high cornering environments, the mount retains its shape under stress.
  
• Precision Feel — the driver senses a closer mechanical connection, improving control feedback.

Diagram Ref No 7A

What This Product Does:

• Support the engine / transmission assembly, holding it in position relative to the chassis.
  
• Isolate vibration and noise, so that engine shake doesn’t overly transmit into the cabin.
  
• Control motion under load, resisting twisting, torque, or movement during acceleration / braking / cornering.

Symptoms Of Failing / Weak Engine Mounts:

• Excess engine movement or shift under acceleration or deceleration
  
• Clunks, knocks, or bangs when shifting or when the engine “settles”
  
• Increased vibration, especially at idle or low RPM in the cabin
  
• Misalignment of driveline (axles, driveshaft, transmission) under load
• Premature wear on exhaust, wiring, hoses — anything connected to the engine that gets stressed when it moves

Why Upgrade To HD RS 75A Mounts:

• Sharper Throttle & Shift Response - Stiffer rubber minimizes drivetrain lag and flex.
• Reduced Engine Twist - Keeps drivetrain geometry stable under load.
• Improved Handling Balance - Less movement means more predictable chassis behavior.
• Enhanced Durability - 75A compound resists collapse and fatigue over time.
• Track-Tested Feedback - Ideal for RS conversions, spirited driving, or track use.

• Porsche 928GT 5.0L 1989-91
• Porsche 928GTS 5.4L 1992-95

Diagram Ref No 12

What This Product Does:

• Linking the two sides — It helps distribute load between the left and right lower control arms, improving how the rear axle reacts to cornering or uneven surfaces.
• Maintaining relative geometry — By coupling the motion of the trailing arms, it stabilizes toe and camber changes under load, improving predictability.
  
• Reducing compliance / slack — The bar and its bushings resist unwanted movement in the lower control arms, preventing them from moving independently in undesirable ways.
  
• Improving handling balance — Helps reduce unwanted rear-end movement, contributing to better rear grip and more consistent behavior over bumps or transitions.
  
  

Symptoms / Signs Of Wear Or Failure:

• Clunking, knocking, or banging noises from the rear suspension over bumps or during load shifts
  
• Rear-end looseness or vagueness — the back of the car may feel less planted or predictable
  
• Uneven or accelerated tire wear on the rear, due to geometry variations
  
• Changes in alignment under load, especially during cornering or when the car is unsettled
  
• Loss of consistent rear grip, especially on transitions or during spirited driving
  
  

Why Replacement Matters:

• Restores rear stability and predictability — with rigid, properly bushing-supported linkage, the rear behaves more reliably
  
• Eliminates noise & slack — worn linkage causes audible play; a fresh bar or good bushings cure that
  
• Preserves alignment / geometry under load — prevents misalignment changes mid-corner
  
• Improves overall handling feel — better feedback, confidence, and consistency
  
• Prolongs life of connected parts — less undue stress on arms, mounts, and bushings

• Porsche 928GT 5.0L 1989-91
• Porsche 928GTS 5.4L 1992-95

Diagram Ref No 27

What This Product Does:

• The rear drop links connect the rear anti-roll bar (sway bar) to the rear suspension arms or linkage.
• When the car corners or one side of the rear suspension moves differently than the other, the drop links transfer force (torque) between the anti-roll bar and suspension to resist body roll.
• They help keep the rear of the car stable and flat in turns, improving grip, balance, and predictability.
• The drop link must allow some articulation to accommodate suspension travel without binding, while maintaining a solid mechanical connection.

Symptoms / Signs Of Worn Or Failed Rear Drop Links:

• Clunking or knocking noise from the rear when driving over bumps or uneven surfaces
  
• Excessive body roll in rear (the rear may lean more in corners than expected)
  
• Loose or vague rear handling — feeling of instability or wandering at the rear
  
• Uneven rear tire wear if the sway bar is not effectively held in place
  
• Noise during braking or transitions — because the sway bar may be loaded or unloaded unevenly
  
  

Why Replacement Matters:

• Restores proper roll control — ensures the rear sway bar is effective and contributes to stability
  
• Eliminates noise & slack — worn links introduce play, rattle, or knock
  
• Improves handling balance — keeps the rear behavior consistent and predictable
  
• Protects other suspension parts — prevents overloading of adjacent arms or bushings compensating for the worn link
  
• Better driver confidence & safety — especially during aggressive driving or in emergency maneuvers

Diagram Ref No 2

What This Product Does:

• The drop link is the connector between the rear anti-roll (sway) bar and the rear suspension arms.
  
• When the car corners, the sway bar resists body roll by transferring torque from one side to the other; the drop link transmits that torque into the suspension.
• It ensures the sway bar is effectively engaged — without a solid connection via the drop link, the bar might float or be ineffective.
• The drop link must allow motion (articulation) to accommodate suspension travel while maintaining a stable connection.

Symptoms Of Worn / Failing Drop Link:

• Clunking or knocking noises from the rear when going over bumps or during cornering
  
• Increased body roll — the rear leans more in corners than it should
  
• Loose or vague handling in the rear — less confidence and feeling of control
  
• Uneven tire wear on the rear wheels if the link allows unwanted movement
  
• Noise under braking or over transitions where the sway bar is being loaded
  
  

Why Replacement Matters:

• Restores rear stability & balance — the drop link ensures the sway bar can do its job resisting roll
  
• Eliminates noise and play — worn links often introduce rattles or slop into the rear suspension
  
• Preserves handling dynamics — maintaining consistent behavior in corners and transitions
  
• Prevents additional wear — a loose link stresses other suspension components as they compensate
  
• Improves safety and driver confidence — especially under spirited driving or sudden maneuvers

• Porsche 928GT 5.0L 1989-91
• Porsche 928GTS 5.4L 1992-95

Diagram Ref No 49

What This Product Does:

• The steering rack is held in place by mount bushings. These bushings absorb vibration, reduce road feedback, and help maintain correct alignment and positioning of the rack under load.
• They prevent the rack from shifting or flexing under steering torque, braking forces, or road irregularities.
• The bushings also provide damping such that minor vibration and harshness are not transferred directly into the steering column or chassis.

Symptoms Of Worn / Failing Rack Bushing:

• Looser, sloppier steering feel — play or “wandering” in the steering wheel
• Clunking or knocking sounds from the steering rack area, especially over bumps
• Uneven tire wear (front) because of slight shifts in rack position / alignment
• Vibration or harshness in the steering input, especially on rough roads
• Increased feedback or harshness from the road transmitted through the steering
• Steering misalignment or drift, as the rack is not held firmly in place

Why Replacement Matters:

• Restores Steering Precision — a good bushing reduces unwanted rack movement so steering response is sharper.
  
• Eliminates Noise & Play — worn mounts often are the source of rattles or looseness in the front end.
  
• Improves Durability of Other Components — when the rack is stable, less stress is put on tie rods, inner joints, and mounts.

• Porsche 928GT 5.0L 1989-91
• Porsche 928GTS 5.4L 1992-95

Diagram Ref No 17

What This Product Does:

• The drop link (also called sway bar link or stabilizer link) connects the front anti-roll bar / stabilizer bar to the suspension arm or knuckle.
  
• Under cornering, the anti-roll bar resists body roll by transferring torque between the two sides of the car. The drop link transmits that torque from the bar to the suspension on each side.
• A properly functioning drop link ensures the bar is effective—in resisting lean—and that the front-end remains stable and responsive.
• It has to allow a degree of articulation (movement) so that as suspension moves up and down, the bar can still maintain its connection without binding.

Symptoms Of Failure / Worn Drop Link:

• Clunking or knocking noises from the front when driving over bumps or uneven surfaces
  
• Excessive body roll in corners—less resistance to lean
  
• Loose or vague front-end handling—the car may feel less crisp or planted
  
• Uneven tire wear if the stabilizer bar is not held consistently
  
• Sway bar becoming less effective—you may notice degraded lateral stability
  
  

Why Replacement Matters:

• Restores the stabilizer bar’s function so the car stays flatter in corners, improving grip and predictability
  
• Eliminates noise and slack in the front suspension caused by worn or loose links
  
• Preserves handling balance—a faulty drop link can lead to uneven behavior between the two sides
  
• Prevents additional wear on related suspension parts that may compensate for a faulty link
  
• Safety & driver confidence—especially important in dynamic driving, cornering, or emergency maneuvers

• Porsche 993 (911) TURBO S 1994-97

Fits On To Diagram Ref No 12

What This Product Does:

• In place of soft rubber bushings, the monoball bearings provide a rigid, low-deflection pivot for the control arms, while still allowing the required angular motion (rotation / articulation) of the suspension.
• Because spherical bearings respond with minimal deflection, the control arm geometry (camber, toe) remains more consistent under load (cornering, braking, acceleration).
• The rigid nature of monoballs helps maintain steering precision and sharper feedback by eliminating rubber compliance (i.e. “mushy” behavior) that would otherwise absorb inputs or distort geometry.
• The Teflon lining ensures smooth motion with minimal friction and wear inside the bearing.

Symptoms Of Worn Or Failing Rubber Bushings:

• Looseness or “play” in steering / feeling soft in the front suspension
• “Wobble” or slight deflection under hard cornering or directional changes
• Changes in alignment under load — e.g. toe or camber drifting
• Poor steering feedback, especially over undulations or when pushing the car
• Vibration, harshness, or unwanted compliance in suspension response

Why Upgrading To Monoball Matters:

• Sharper steering response & feedback — no rubber compliance dulling input
  
• Better alignment retention under load — more consistent camber / toe through suspension travel
  
• Greater precision in handling, especially during cornering, transitions, or high lateral forces
  
• Less geometry distortion when pushing the car hard or under braking
  
• Durability under load — well-made monoball bushings resist deformation better than aged or overworked rubber
  
• Ideal for motorsport / track setups where predictability and consistency matter more than comfort

• Porsche 993 (911) TURBO S 1994-97

Fits On To Diagram Ref No 3, 4, 5, 6

What This Product Does:

• Firm Locating: The monoball cartridge provides a rigid pivot point with minimal unwanted flex, so the arm’s geometry is better preserved under load.
• Articulation: Unlike a fully rigid mount, it allows the necessary rotational and angular movement (pitch, yaw) in the control arm, but with less compliance.
  
• Precision: Because the deflection is greatly reduced, alignment settings (camber, toe, caster) remain more stable throughout suspension travel.
  
• Feedback & Connection: You feel more direct input — the suspension reacts more faithfully to changes with less “softness” from rubber compliance.
  
• Durability & Serviceability: Good monoball designs are sealed to exclude contaminants, and may be serviceable or greasable, extending their life compared to plain spherical bearings.
  
  

Symptoms Of Worn Rubber Bushing:

• Clunking, knocking or rattling from the rear suspension
• Unpredictable rear behavior during cornering or transitions
• Rear alignment settings shifting under load (camber / toe changes)
• Uneven tire wear on the rear — especially inner or outer edges
• A vague or soft feel to the rear — the car may feel less composed
• Loss of rear grip consistency under hard driving

Why Upgrading To Monoball Matters:

• Maximizes Consistency — geometry holds under stress, reducing alignment drift lap after lap.
  
• Improves Rear Feel — sensing changes becomes sharper, with more precise feedback.
  
• Better Handling Under Load — less compliance means less suspension “wobble” or deflection in corners.
  
• Protects Other Parts — less slop means less stress on trailing links, arms, and mounting points.
  
• Balanced Design — unlike hard solid mounts, monoball retains articulation, reducing binding and fatigue issues.
  
• Upgrade & Value Add — often used in track / restore builds as a high-performance component.

HD Transmission / Gearbox Mount Bush.
Enhance drivetrain control and shifting precision with the HD Transmission / Gearbox Mount Bush.
Engineered for Porsche 964 and 993 C2 models, this heavy-duty mount replaces the soft factory bushing with a stiffer, high-durometer rubber compound that improves gearbox stability and alignment under load.

Fits:

• Porsche 964 (911) C2 1989-93
• Porsche 993 (911) C2 1994-97

Diagram Ref No 23

What This Product Does:

• Support & Locating Function - The mount holds the gearbox housing in its proper position relative to the chassis. It resists movement under torque, acceleration, braking, or other loads.
• Vibration Damping / Noise Isolation - The rubber or elastomer absorbs vibration and noise from the transmission so that it doesn’t transmit harshly into the cabin.
  
• Control Twist / Deflection Under Load - Under torque or rapid load changes, the transmission tends to twist or shift slightly. A good mount restrains that movement, preserving alignment and reducing strain on connected parts (driveshafts, couplings, etc.).
  
• Maintain Drivetrain Geometry - By limiting excessive movement, it helps maintain the correct angles and alignment of drivetrain components, which is important for durability and performance.
  
  

Symptoms Of Worn Or Weak Mounts:

• Thumping, clunking, or bangs when shifting gears, accelerating, or decelerating
  
• Excessive vibration or harshness in the cabin, especially at idle or under load
  
• Gear lever play or misalignment under load
  
• Delayed or vague shift feel, due to movement or flex in the mount
  
• Wear on drivetrain components, as undue movement induces stress in shafts, joints, couplings
  
• Mount failure (cracks, splitting, excessive deformation) visible on inspection
  
  

Why The HD Version Upgrade Matters:

• Tighter drivetrain response — less flex means more immediate reaction during shifting or throttle transitions
  
• Improved alignment consistency — better control of the gearbox position helps preserve ideal geometry under stress
  
• Reduced noise and slop — sharper operation, less perceptible movement
  
• Better durability — stiffer (HD) rubber resists aging, compression set, and breakdown better than older soft rubber
  
• Balanced vibration control — while firmer than stock, remains less harsh than fully solid mounts, striking a good compromise for street / performance use
  
• Straightforward replacement — fits into the stock bracket, so installation is simpler than aftermarket custom mounting

• Support & locate the gearbox - The mounts hold the transmission housing securely to the chassis or subframe, maintaining alignment between the gearbox and the driveshafts.
• Dampen vibration & isolate noise - The rubber or elastomer in the bushings absorbs vibration from the transmission and drivetrain, preventing harshness from transferring into the cabin.
  
• Limit movement under torque - Under acceleration, deceleration, or shifting loads, the gearbox wants to twist or shift slightly. The mount bushings resist that motion, constraining it to acceptable levels.
  
• Maintain geometry & protect components - A stable mount ensures the angular relationships and alignment of the drivetrain (driveshafts, couplings, mounts) remain correct under load.
  
  

Symptoms / Signs Of Worn Or Failed Mounts:

• Clunking, thuds or knocks from the gearbox area when shifting or under throttle
  
• Increased drivetrain vibration felt in the cabin
  
• Loose or laggy gear shifts, or slight misalignment registering as “play”
  
• Excess movement / twist of the gearbox under load
  
• Stress or wear on driveshafts, universal joints, or coupling components
  
• Noise under load changes — e.g. when engaging or releasing throttle
  
  

Why Replacement Matters:

• Restores drivetrain stability and response — tighter mounts reduce slack that dulls shift feel and throttle response
  
• Protects other drivetrain parts — controlling movement reduces undue stress on joints, couplings, and shafts
  
• Maintains alignment & lug angles — consistent mounts help preserve correct geometry even under load
  
• Eliminates noise & vibration due to degraded bushings
  
• Ensures proper operation — a failing mount can cause accelerated wear or even damage
  
• Maintains value & reliability — restoring mount integrity is important for longevity, performance restoration, and driver satisfaction

Diagram Ref No 18

What This Product Does:

• The drop links serve as the link between the rear stabilizer (anti-roll) bar and the suspension.
• When the car corners, the anti-roll bar tries to transfer force from the side of the car compressing to the side extending. The drop links transmit that force into the suspension, helping reduce body roll at the rear.
• They maintain the correct geometric relationship so the anti-roll bar functions properly — without them, the bar is decoupled and ineffective.
• The drop link must allow articulation but resist unwanted flex or play, so quality joints / bushings are essential.

Symptoms Of Worn / Failing Rear Drop Links:

• Clunking or knocking noises at the rear over bumps or rough roads
  
• Excessive body roll in the rear during cornering
  
• Loose or vague rear handling — less confidence in rear grip
  
• Uneven rear tire wear if the rear bar is not being held in place properly
  
• Rear end sway or instability, especially under load or fast direction changes
  
• The anti-roll bar may appear to have slack or move independently if the link is too loose or broken

Why Replacement Matters:

• Restores Suspension Geometry – Keeps the rear anti-roll bar working properly.
  
• Eliminates Noises & Play – Prevents knocking and vibration caused by worn joints.
  
• Improves Handling Stability – Ensures balanced cornering and predictable grip.
  
• Protects Suspension Components – Prevents excess strain on bushings and control arms.

Diagram Ref No 5, 7 And 8

What This Product Does:

• The drop link (also known as an anti-roll bar link or stabilizer bar link) transfers forces between the anti-roll (sway) bar and the suspension components, helping resist body roll when cornering.
• It ensures that the anti-roll bar works effectively by holding the bar in place and transferring lateral load.
  
• It maintains consistent roll stiffness front-to-rear and helps the car stay flatter through turns.

Symptoms Of A Worn / Failing Drop Link:

• Clunking / knocking noises from the front suspension, especially over bumps or uneven surfaces
  
• Excessive body roll — the car leans more in corners than usual
  
• Loose / vague handling or degraded front-end response
  
• Uneven tire wear — if the suspension geometry is not held properly
  
• Noises under braking or turning — because the bar may shift or flop
  
  

Why Replacement Matters:

• Restores anti-roll bar function & balance — without a good link, the anti-roll bar is ineffective on that side.
  
• Eliminates noise & play — worn links often produce rattling, knocking, or slack.
  
• Improves handling & stability — ensures the suspension responds as designed under lateral loads.
  
• Preserves other components — keeps undue stress from being transferred to arms, bushings, or joints.
  
• Better safety & predictability — especially in emergency maneuvers or spirited driving.

Sold As A Set Of 2 bushes (4 halves).

Fits:

• Porsche 911 1987-1989 3.2L G50

Fits On To Diagram Ref No 1

What This Product Does:

• The HD version is made from rubber with roughly 25 % higher durometer (i.e. stiffer) than original rubber mounts.
• It fits into the stock mounting brackets / spacers (i.e. “installs in stock transmission mount hangers replacing worn factory rubber”) 
• Because it is semi-solid rather than full solid, it retains some vibration isolation while cutting down drivetrain slop.

Symptoms Of Worn Or Soft Gearbox Mounts:

• Thuds, clicks, or knocking noises from the drivetrain, especially under shifting or torque load
• Excessive vibration felt in the cabin or floorboard
• Drivetrain “slop” or delayed response when you apply or remove throttle
• Shifts may feel less crisp due to slight misalignment or movement
• Additional stress on driveshafts, couplings, or mount brackets
• Transmission housing might appear to move or twist during load changes

Why Upgrading Matters:

• Improved Shift Feel & Response — with less drivetrain flex, shifts feel more direct
  
• Better Drivetrain Alignment Under Load — geometry stays more consistent under torque
  
• Reduced Clunk / Play — eliminates slack or movement that can degrade feedback
  
• Durability — stiffer rubber lasts longer, resists deformation, aging, and oil exposure
  
• Balanced NVH — better than stock in performance use, but not as harsh as full solid mounts
  
• Plug-and-Play Fitment — designed to use original mount brackets and spaces

Diagram Ref No 10

What This Product Does:

• The control arm mount bracket with bushings holds the rear end of the front lower control arm in place. It constrains rearward / forward movement and helps stabilize lateral forces on the arm.
• It acts as a pivot and anchor point, allowing the control arm to move up and down with suspension, while resisting unwanted deflection under load (cornering, braking, acceleration).
• Because it’s in the rear position of the arm, it is subject to forces that might push or pull the arm fore/aft, so a stable mount is critical for alignment.
• In the HD / stiffer version, this mount limits deflection under load, which helps maintain alignment (especially toe) and reduces undesirable movement that can degrade handling precision.

Symptoms / Signs Of Wear:

• Clunking / knocking noises from the front suspension, especially from the control arm area
  
• Loose or vague steering feel, especially under cornering or over bumps
  
• Front-end alignment shifts under load, especially toe changes when braking or accelerating
  
• Uneven / accelerated front tire wear, especially on the front tires
  
• Reproducible shudder or instability during transitions (e.g. turning into a corner)
  
• Excessive vibration or harshness transmitted through the suspension if the buffering is compromised
  
  

Why Upgrading (HD version) Matters:

• Improved Handling Precision: By reducing deflection under load, the HD mount helps maintain consistent suspension geometry, giving sharper steering response and more predictable behavior.
  
• Better Alignment Retention: Less movement helps the toe/camber settings stay where they should under braking, cornering, and load changes.
  
• Eliminates Noise & Play: Worn mounts let arms move, causing clunks or play. A stiffer mount restores tightness.
  
• Durability / Longevity: Higher durometer (stiffer) material resists aging, fatigue, and deformation better than softer factory rubber.
  
• Track / Sport Use Capability: On spirited driving or track days, the extra stability is noticeable — less wobble, better feedback, and more control.
  
• Better Front-End Behavior Under Load: Because the arm is more securely anchored, the forces are better managed, reducing unwanted movement that might upset balance.
