About RSS

RSS for Porsche

RSS parts for Porsche at Design911 focus mainly on suspension and chassis components, aimed at drivers who want sharper response and improved precision for fast-road and track-biased setups.

A Quick Look at RSS

RSS information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where RSS is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector or mounting type where relevant.

  • Typical reasons to choose RSS include reducing compliance at key suspension points, improving steering feel, and helping alignment settings stay consistent under load for fast-road or track use.
  • Common side effects or issues can include increased NVH, squeaks if parts are not lubricated correctly, and binding or “nervous” handling if components are installed or torqued incorrectly, or if the car is not aligned afterwards.
  • Handling that feels too harsh or edgy is often linked to over-stiff choices for the car’s use, or upgrading one area of the chassis without keeping the overall setup balanced.
  • Plan for a proper alignment after fitting suspension or geometry parts, and consider upgrading in stages so you can keep the chassis balance where you want it.
  • Where suspension parts are replaced, checking and correcting geometry is important for predictable handling, even tyre wear, and stability under braking and acceleration.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Suspension & Axle

Suspension and axle parts in RSS and related ranges are typically chosen to restore or sharpen your Porsche’s handling, ride comfort, and braking stability. Replacement is usually driven by wear, age, or the desire for a firmer, more controlled setup, especially where knocking, wandering, vibration, or uneven tyre wear are present.

  • Replace suspension components in balanced pairs (left/right) where applicable and schedule an alignment afterwards to avoid instability and irregular tyre wear.
  • Start by diagnosing play and wear in joints, bushes, and mounts rather than replacing parts at random.

Suspension Upgrades

Suspension upgrades are where RSS typically features, helping reduce body roll, improve steering response, and tailor your Porsche for road, fast-road, or track-day use. Choices usually depend on how firm you want the car to feel, desired ride height, and how much adjustability you need.

  • Clarify your goal (comfort versus response) before choosing spring rates, bush materials, or damper setups and plan for correct geometry and, where needed, corner balancing.
  • Poorly matched upgrades or skipped setup work can cause harshness, bottoming, tyre rubbing, or inconsistent handling, so treat the car as a complete system.

Anti Roll Sway Bar

Anti-roll (sway) bars and associated RSS hardware are used to reduce body roll and fine-tune handling balance on Porsche models. They are often upgraded when owners want crisper turn-in, a change in understeer/oversteer balance, or when refreshing a corroded or damaged factory bar and its bushes/links.

  • Most noises blamed on the anti-roll bar are usually from drop links or bushes, so inspect these at the same time and consider replacing them together.
  • Avoid extreme stiffness changes at just one end of the car to keep the handling balance predictable, and expect a small effect on ride comfort over single-wheel bumps.

Control Arms Front

Front control arms and RSS front arm solutions are fitted to restore or refine steering accuracy, braking stability, and wheel geometry on your Porsche. They are typically replaced when bushes or ball joints wear, causing knocking, vague steering, or uneven tyre wear, or when a firmer option is desired for sharper response.

  • Plan a full alignment after replacing front arms and, where possible, renew both sides together for consistent behaviour.
  • Check related components such as top mounts, drop links, and track rods so you do not chase the same noise or vibration after replacement.

Control Arms Rear

Rear control arms are important for keeping rear alignment stable and maintaining predictable handling. RSS components in this area are often chosen when drivers want improved stability under acceleration and over bumps, or when worn bushes are causing rear steer effects, instability, or uneven rear tyre wear.

  • Rear alignment is essential after arm replacement, particularly where camber and toe are adjustable.
  • Assess the full rear linkage set, as refreshing several aged arms and bushes together can give a more consistent and durable result than replacing one item in isolation.

RSS XL TARMAC SERIES XL 2-PIECE COMPLETE LOWER CONTROL ARM KIT - Rear Axle (Pair of 2).

rss

RSS Tarmac Series Motorsport Lower Control Arms are specifically engineered for use on lowered vehicles that have reduced travel struts/dampers such as PASM or M030 option. Alternatively if the car is equipped with high quality aftermarket or motorsport coilover kits ie Bilstein PSS10, KW V3 or Ohlins etc.

The Lower Control Arms are NOT COMPATIBLE with "Base Model Suspension" (long travel struts/dampers) or "Base Model struts/dampers with lowering springs."
Caution: Do not install on vehicles with Base Model struts/dampers as it may result in an unsafe driving condition with possibility of suspension bind when struts/dampers are fully extended or in full drop.


Fits:
FOR REAR AXLE PORSCHE 986, 996, 997, 987, 981/982/718

Includes:
- Adjustable/Non-Hydraulic Replacement Thrust Arm Bushings,
- 1mm/2mm/3mm/7mm Shims,
- Spherical Monoball Ends.
*** Note: 981 and 991 Models may require additional Front Litronic or Torque Vector Sensor Brackets.

RSS Tarmac Series Motorsport Lower Control Arms are specifically engineered for use on lowered vehicles that have reduced travel struts/dampers If you need assistance in identifying your suspension type please contact us. For specific fitment information refer to the "Chassis Fitment Guide and Lower Control Arm Fitment Notes" (See Images Below).

The RSS Tarmac Series – Motorsports Control Arms are designed for the Porsche driver who demands the absolute maximum in precision handling, feedback and control from their chassis. This system has been specially engineered to provide unmatched performance, quality, strength and serviceability. RSS Tarmac Series Control Arms address the performance related shortcomings of the OEM rubber mounted suspension components which were designed to reduce road noise and vibration for everyday street use. The use of rubber injected moldings in mounting components such as the control arms, thrust arms, upper links and toe arms is a compromise in regards to maximum suspension performance. The soft rubber deflects under suspension load which in turn causes unwanted movement (deflection) between the suspension and chassis. Data also shows that temporary changes in spring rates can occur as well. These movements and changes result in unnecessary corrections and inputs from the driver.

FEATURES & BENEFITS:
• Replaceable Sub-Assemblies: For the extreme, repetitive track day enthusiast or racer, our high strength
steel alloy spherical bearings (with a friction reducing, longevity increasing Teflon liner) outer and inner arm sub-assemblies can be replaced
unlike the motorsports arms, in which case a new set of arms will need to be purchased if the
spherical bearings are worn out.
• Adjustable Suspension Geometry: Adjust dynamic camber values and roll center heights with our
unique zinc plated steel bushings.
• Solid Monoball Control Arm Ends: Offers better handling and a more responsive suspension over the
factory one-piece rubber injected control arm by eliminating bushing deflection (also uses the same
high strength steel alloy spherical bearing found in our control arm monoball kit).
• 6061 Aerospace Grade Billet Aluminum Construction: Allows for a more uniform molecular structure
at every point of the arm over the cast components providing a more durable and inherently
stronger part. Manufacturing from billet aluminum rather than casting results in fewer impurities in
the metal.
• Anodized Aluminum Surfaces and Zinc Plated Steel Parts: Allows for better corrosion resistance
against the elements.

AVAILABLE FOR MOST PORSCHE 996, 986, 981, 982, 987 & 997 MODELS INCLUDING TURBO, GT2, GT2RS, GT3 & GT3RS.

RSS TARMAC SERIES Motorsports Suspension Kits have been winning championships and races in various forms of motorsport (Road Racing to Rally) around the world. RSS is the suspension of choice of professional race teams, tuners, track day junkies, and driving enthusiasts around the world.

Fits:

Porsche 996 C2, C4, C4S, Turbo, GT2, GT3

With factory hydraulic engine mounts, the drive train will move independent of the chassis during acceleration and cornering loads. This movement can upset the balance of the vehicle and create negative handling effects.

RSS Tarmac Series Performance Engine Mounts minimise these effects by utilising specialised polyurethane bushings which offer a firmer, more direct driving feel with optimum feedback. This upgrade will not adversely effect ride quality or cause knock sensor issues commonly associated with solid engine mounts.
