Suspension Secrets Stage 2 Rear Top Mount Camber Plate For 718 Porsche GT4 RS

Maximise the potential of your Porsche Cayman GT4 RS with our ground breaking world first upgrade that allows you to install and run up to a 325 rear profile tyre with no body modifications or any other permanent modifications required. Previously considered impossible, our Stage 2 Rear Top Mount Camber Plate offers a design that allows you to package a 325 section tyre on the stock body. 

Determined to push the boundaries with our very own 718 GT4, we relentlessly pursued a solution to installing the same tyre widths as a 991.2 GT3 RS Weissach on the front and rear axles of our GT4. After months of development and road/track testing we created a solution to make this possible - all whilst retaining the OEM dampers, PASM and OEM bump/droop ratio of the rear dampers. 

With our direct bolt-on replacement Stage 2 Rear Top Mount Camber Plate fitted alongside some additional components you can successfully install a 325 width rear profile tyre inside the stock body with no additional modifications required. It allowed us to pull an incredible 1.785G on circuit using road tyres and reduced the lap time set by our professional driver by over 3 seconds on a 1min 39.5sec lap. 

The additional components required are listed below and are available as options on this product listing. All of these parts are absolutely required to make this tyre fitment possible. We have separated the options in case you already have some of these upgrades fitted to your car: 

• Adjustable Rear Toe Control Arms
• Shorter Rear Main Springs (170mm long) 

With all of these components fitted we have designed the optimum wheel sizes to sit the wheel and tyre perfectly in the space available to prevent any contact with the bodywork or suspension components. The exact wheel dimensions to make a 265 front tyre fitment and 325 rear tyre fitment possible are:

• Front Wheel Specs - 20" x 9.5j et52
• Rear Wheel Specs - 20" x 12j et45

We developed this system with a Bola CSR alloy wheel and Michelin Cup2 tyre. You can also use a 19-inch alloy wheel with the same widths and offsets if you wish to use smaller wheels. 

Our front Suspension Secrets Camber Caster Top Mounts will also be required to fit the 265 profile front tyres within the wheel arches which are available and listed separately.
