A corner uprights were redesigned and have larger outside 8x16x5mm ball-bearings for increased reliability and life-span. To give the set-up alternatives, one more lower roll-center modification place was added. The smart design enables exactly the same upright to be used on both remaining & right edges. The lower suspension system pin where a corner upright sits features 2 shims for wheelbase adjustment. The rear uprights feature built-in geometry adjustments including: camber, upper and lower roll center and wheelbase.
