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.

Rennline Battery Relocation Kit without Kill Switch Mount

To be fitted with 680 Odyssey Battery

rennline

Fits:
Porsche 911 LHD Only

Relocating a lightweight battery to the smugglers box is a standard modification to track and high-performance street 911's. The stock 911 battery is much heavier than necessary (upward of 40 pounds heavier than an Odyssey 680), and is located in the front left of the car, where it contributes to poor weight distribution. Until now, relocating a battery to the smugglers box (the smugglers box is the small compartment in the front trunk behind the fuel tank, on the passenger's side) required fabricating your own mounting and bracket system. Rennline's new relocation kit is a fully adjustable aluminum assembly that makes battery relocation an easy afternoon project. This newly designed unit is a complete bolt in assembly which requires absolutely no drilling and fully suspends the battery eliminating unwanted vibration. Kit includes all necessary stainless steel hardware and full installation instructions. We also offer an optional Smugglers Box Lid that is a perfect location to mount a cut off switch.

Note: Switch, remote pull, smugglers box cover, and battery are not included with this or any of the kits.
