Lightweight yet ultra-strong rear upright molded from special graphite composite material. Features larger outside 8x16x5mm ball-bearing for increased reliability and life-span. Graphite rear upright is very strong and makes the rear of car very stable, yet is very light taking some load off of the rear suspension. Improves bump absorbing and handling on bumpy tracks.

To extend the set-up alternatives, an additional lower roll-center adjustment position was added. Suitable for most track conditions, especially for medium- and high-traction tracks.

The smart design allows the same upright to be used on both left & right sides. The lower suspension pin on which the rear upright sits features 2 shims for wheelbase adjustment.

The rear upright features integrated geometry adjustments including: camber, upper and lower roll center and wheelbase.
