Suspension Secrets Rear Top Mount Camber Plate Stage 1 - Porsche 718 GT4 RS
All Prices Include VAT
Transform the rear axle grip of your Porsche 718 Cayman GT4 RS on road and track with the Suspension Secrets Rear Camber Top Mounts for the Porsche 718 Cayman GT4 RS.
Installing wider tyres on your Cayman GT4 RS can significantly increase grip levels. Moving from a standard 295 rear tyre profile to a 305 rear tyre profile will offer a significant boost in grip levels. As standard, a 305 tyre will make contact with the rear arches making it not possible to operate.
We have designed a direct bolt on replacement rear top mount with offset rear camber to fit a 305 width rear tyre on the standard wheels inside the rear wheel arches and prevent any contact from occurring. The OEM damper ratio is also maintained meaning there is no difference in damper travel with our upgrade installed. Our top mount also works directly with the OEM rear damper and retains the PASM system.
We have designed and developed this solution to provide full clearance on the wheel arches, arch liners and suspension components with a 305 width tyre installed on a standard rear wheel. This increases rear tyre width, significantly increasing overall grip levels, allowing you to push even harder out on circuit.
An adjustable rear toe arm is advised to install with our rear camber plate to ensure that rear geometry can be maintained with the upgrade fitted. To include the adjustable rear toe control arm, you can add it in the options on this listing.
This camber plate also allows for more rear axle camber to be used compared to standard due to the offset in the camber plate. OEM camber levels are also attainable using the standard rear camber adjustment points once our plates are installed.
No other modifications are required, allowing for a significant increase in grip levels with this simple bolt on upgrade.
A common pairing is the 255 profile front tyre to help balance the car with a 305 fitted. In order to install a 255 profile front tyre to the standard wheels and prevent any arch contact from occurring our front Camber Caster Plate Top Mounts will also be required which are listed on the same product page.
