Hey guys new to the forum here I'm building my GTI for canyons and track and it looks like the BC coils are the best way to go, problem is the rear spring rate is too soft and they are unable to customize the rate. I'm looking to install a 12k rear spring. Does anyone know if there is another car that has the same spring dimensions?
spring top diameter 104mm
spring bottom diameter 96.5mm
free length 180mm
