Choosing the Right Fit for Your Porsche

Where Rennline 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 type where relevant.

  • Typical reasons to choose Rennline parts include improving pedal feel and control, tidying cabin storage and organisation, adding lighter or stronger components, and achieving a clean motorsport-inspired finish for upgrades and restomods.
  • Common issues when fitting accessories include rattles, squeaks, scuffed finishes, and poor alignment, often caused by incorrect hardware, missing threadlock, or mixing parts between different Porsche generations.
  • Watch for symptoms after installation such as new noises, vibration, or panels that don’t sit correctly, and re-check torque settings and alignment if anything feels or sounds wrong.
  • Keep your original Porsche parts where possible so most Rennline upgrades can be reversed later if you want to return the car to standard.
  • Reduce cabin noise or vibration changes by understanding that more motorsport-focused components can transmit more sound and feel through the body shell.
  • Test-fit parts before final assembly, using the correct fixings and torque values, to avoid rattles, misalignment, or damage to surrounding trim.

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 components are changed to restore safe handling, ride comfort, and braking stability on your Porsche, or to achieve a different balance between comfort and control where upgrades are available.

Shock Absorber Parts FRONT — Front shock absorber parts such as mounts, bearings, bump stops, and hardware are replaced to support new dampers, reduce knocks and creaks, and keep the front suspension of your Porsche working smoothly and quietly.

Suspension Upgrades — Suspension upgrades let you fine-tune how your Porsche rides and handles, reducing body roll and sharpening response when matched correctly to the car, alignment, and intended use.

Control Arms Front — Front control arms are typically renewed to cure knocking, vibration, and uneven tyre wear, and to bring back precise steering and braking stability on your Porsche.

Top mounts Front — Front top mounts are replaced when there are knocks over bumps, creaks when steering, or vague steering feel, helping maintain correct geometry and smoother suspension movement.

Motorsport Product that replaces the original Porsche part No. 993331043, or 99333104300, Lower Rear Control Arm.

If you're serious about how your 993, 996, 997, Cayman, or Boxster handles, you should upgrade the rear suspension with adjustable control arm links. There are two major drawbacks to the factory links: 1) You can't lower your car and maintain proper suspension geometry. The factory links create too much toe-in, which cannot be adjusted out, creating handling problems and excessive tire wear. 2) The factory links have rubber bushings, which make handling imprecise, especially in performance driving when suspension loads are highest.

Rennline adjustable control arm links solve both these problems. Manufactured from 6061 aluminum and feature a turnbuckle design that allows each arm to be lengthened or shortened as needed to restore proper suspension geometry on a lowered Porsche. The FK Teflon-lined rod end bearings ensure precision handling and lock in your car's alignment settings, ensuring predictable cornering under all conditions. Unlike the competitors' product, Rennline arms come with eccentric locks and new hardware so you can completely eliminate the factory setup, which is known to go out of adjustment under hard driving and ruin your car's alignment.

Porsche 993*

* For cars with factory Boge shocks please call for fitment details. ** Note: RS style spring hats required.

Camber Plates/Strut Mounts - Under extreme conditions, such as road racing and autocross, negative camber is required to keep as much of the tire's contact patch on the road as possible. Stock suspension mounts will not allow you to achieve the necessary amount of negative camber required for this type of performance driving. Rennline's Sealed camber plates incorporate FK motorsports Teflon-lined spherical bearings and eliminate the indistinct feedback associated with factory rubber mounts. Why are Rennline's strut mounts the best ?

• Drastically increased bearing life due to the integrated factory GT3 weather seals.
• FK Motorsports Teflon-lined spherical bearings.
• Rigid bearing mount, not clipped in like some products available.
• Can be used with all factory and aftermarket struts, Including factory non adjustable units. Call for details.

Sealed Monoball Cartridges - Front and Rear - Most Porsche owners today, especially those of us who take our cars to the track, have equipped our cars with tires much wider and stickier than stock, which allows higher g-forces to be achieved in cornering and braking. During that type of hard driving, rubber suspension bushings are compressed and flexed by the extreme loads being put on them, defeating your car's finely tuned alignment settings, thereby reducing your braking and cornering potential. Mono balls are a downside-free improvement; because they eliminate four important sources of suspension slop without making your car's ride harsher. Your Porsche will handle and brake with greater precision, predictability, and feedback to the driver. Rennline mono balls are equipped with FK Motorsports bearings, cadmium-plated and Sealed to prevent premature wear due to moisture or dirt contamination, ensuring long track or street life.
