Finally, a solution that allows you to safely increase without the risk of damaging your front axles. As you add GT3 shims to your front Porsche 996/997 Turbo lower control arms, you move the CV joints beyond their safe range of motion, risking failure and expensive damage. These 10mm thick precision spacers, used with 16mm of LCA shims will provide an additional -1.7 deg. of camber, while maintaining the factory CV joint and axle relationship. The spacer design features a concentric lip that positively and accurately locates it to the CV joint for perfect balance and no vibration. Each kit includes two spacers and all the needed hardware in high class 10.9 grade.
