Rennline Clubsport Camber Plate Top Mount Set.
SET OF 2
Fits:
Porsche 991/981/718 2WD except GT3/GT4
Whether you use your car on the street or the track, optimum camber settings are critical for both performance and tire wear during spirited street driving and at the track. These plates were designed for 991/981 owners looking to achieve additional camber without needing to change to GT3-style adjustable control arms. By using an offset bearing housing, the range of possible camber adjustment is shifted to provide an additional 1.1 degrees of camber at all OEM-equivalent settings.
These mounts are CNC machined in house from 6061-T6 billet aluminum for maximum strength while keeping weight to a minimum. Precision teflon lined bearings are held in place with a two-part threaded housing which eliminates the issues commonly associated with camber plates that utilize a snap ring such as excessive noise and premature failure. This also minimizes camber changes under load meaning you have more precise alignment settings when it matters most.
Designed specifically for cars using factory shocks and any aftermarket setup designed to work with OEM mounts, this is the easiest and simplest way to gain camber in your 991/981 car. In addition, by making camber changes at the top of the strut instead of at the control arm, caster changes are minimized resulting in an easier setup and minimizing necessary modifications.
• 1.1* increase in negative camber at factory settings results in greater range of adjustment
• CNC machined housings
• Fully compatible with factory and aftermarket shock/spring kits utilizing factory mounts
• Equalize tire wear and maximize traction at once
• Precision teflon-lined spherical bearing
• Reduced compliance results in more precise handling and alignment

Rennline Race Spec Camber Plate FRONT Top Mount Set.
SET OF 2
Fits:
Porsche 991 / 981 / 718 2WD incl GT3/GT4 FRONT
If you are looking for maximum performance and adjustability from your 991/981 you are going to want to be in complete control of your camber settings. Designed to work with non-OEM suspension options such as JRZ, Moton and GT3/Cup struts, Rennline Race Spec Camber Plates will give you perfect combination of adjustability and durability.
this kit will fit the Cayman GT4 and 991 GT3 with OEM dampers.
These mounts are CNC machined in house from 6061-T6 billet aluminum for maximum strength while keeping weight to a minimum. Precision teflon lined bearings are held in place with a two-part threaded housing which eliminates the issues commonly associated with camber plates that utilize a snap ring such as excessive noise and premature failure. This also minimizes camber changes under load meaning you have more precise alignment settings when it matters most.
Designed for anyone from the weekend enthusiast to the dedicated track day veteren, these camber plates allow you to add camber in the optimum way. Swapping to GT3-style lower control arms can increase camber significantly, but it comes at the cost of reduced caster without replacing additional components. Our Race Spec Camber Plates solve this issue by adding camber at the top of the strut, minimizing geometry changes to other areas of the suspension system.
• 1.1* increase in negative camber
• CNC machined housings
• Designed for use with non-OEM style coilovers and struts
• Equalize tire wear and maximize traction at once
• Precision teflon-lined spherical bearing
• Reduced compliance results in more precise handling and alignment

The concave washer sits within the shock absorber mounting assembly and helps evenly distribute clamping force across the suspension components. Its specially formed curved profile supports the correct positioning of the shock absorber mount, helping maintain suspension geometry and reducing stress on mounting surfaces during suspension movement.
Functions & Technical Role
•  Load distribution: Spreads suspension forces evenly across mounting points
•  Mounting support: Assists correct positioning of the shock absorber assembly
•  Suspension stability: Helps maintain proper suspension alignment under load
•  Vibration control: Reduces stress and movement within the mounting assembly
•  OEM precision: Manufactured to Porsche specifications for exact fitment and durability
Fitment / Position on car
•  Fitting position: Front axle suspension
•  Location: Shock absorber / strut mounting assembly
•  System: Front suspension and damping system
The concave washer supports correct suspension mounting geometry and helps prevent uneven stress on suspension components. Proper load distribution is essential for maintaining ride quality, handling precision, and long-term durability.
When to Replace
•  During shock absorber or suspension overhaul
•  Damaged, bent, or corroded mounting hardware
•  Suspension noise or movement from the strut assembly
•  Following accident or suspension impact damage
•  When replacing associated suspension mounting components
