Constructed from durable automotive-grade materials, the cover plate is engineered to withstand the stresses generated by suspension movement, steering inputs and road impacts. Featuring a single-bore design, it provides precise alignment and support for the associated top mount assembly while helping maintain the structural integrity of the suspension mounting area.
What This Product Does:
- Secures and supports the front suspension top mount assembly.
- Helps distribute suspension loads into the chassis structure.
- Maintains correct positioning of suspension mounting components.
- Supports proper suspension geometry and alignment.
- Protects the top mount installation area.
- Contributes to suspension stability and handling performance.
- Helps ensure reliable operation of the front suspension system.
- Supports long-term structural integrity of the mounting assembly.
Symptoms Of Wear Or Failure:
- Looseness within the suspension top mount assembly.
- Suspension knocking or clunking noises.
- Visible corrosion or deformation of the cover plate.
- Misalignment of suspension mounting components.
- Excessive movement at the top mount location.
- Uneven suspension loading.
- Premature wear of top mounts and associated hardware.
- Difficulty maintaining suspension alignment.
- Visible damage caused by impact or corrosion.
Why Replacement Matters:
- The front suspension mounting area is subjected to constant forces generated by steering, braking, cornering and road surface irregularities. Over time, mounting hardware and cover plates can suffer from corrosion, fatigue, impact damage or distortion, reducing their ability to properly support the suspension assembly.
- A damaged or weakened cover plate can compromise suspension stability and place additional stress on top mounts, shock absorbers and surrounding chassis components. If left unresolved, mounting issues may lead to accelerated suspension wear, reduced handling precision and costly repairs.
- Replacing a worn or damaged cover plate restores secure suspension mounting, maintains proper load distribution and helps preserve the integrity of the front suspension system. An OE Match replacement provides factory-style fitment, durable construction and dependable long-term performance, ensuring your Porsche continues to deliver the handling, comfort and safety expected from its suspension design.

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

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
