Molded composite rear upright with 2 roll center positions, used on left or right side. The very compact rear uprights are small in size but thanks to the special composite mixture used also very strong. The lower roll center adjustment has 2 different positions on the upright and the upper roll center adjustment has 3 different positions. The rear uprights feature 0° toe to ensure stability and prevent suspension geometry changes in hard crashes.
For maximum drive train reliability larger 5x12 ball-bearings are used in the outer position with increased dynamic load. On the inner position the smaller 5x10 ball-bearings are used to minimize unsprung weight.
