The trunk uprights were redesigned and show larger outside 8x16x5mm ball-bearings for increased reliability and life-span. To extend the set-up alternatives, an additional reduced roll-center modification position ended up being added. The smart design enables the exact same upright to be utilized on both left & right edges. The lower suspension system pin which a corner upright sits features 2 shims for wheelbase modification. The trunk uprights feature integrated geometry changes including: camber, upper and lower roll center and wheelbase.
