XX Rear shock tower
The shock tower is made from 6mm CF. It features the same anchor points as the stock parts for all XX generations, from the original XX to the XX-CR KE and allows the use of modern wing mounts (B6 wing mount #91718 pictured).
You get a stiffer wing mount as well as a stronger shock tower.
You can fit the motor wires under the tower for the cleanest look.
