XRay Aluminium Rear Lower 1 Piece Suspension Holder - Rear - Rr

The XRay Aluminium Rear Lower 1 Piece Suspension Holder - Rear - RR (XR333721) is a CNC-machined mount for the rear of the rear bulkhead, made from premium Swiss 7075‑T6 aluminium. It retains the proven NT1 geometry while offering a durable, one-piece solution for mounting the rear suspension arms.

The refined mounting system lets the arms move very freely for higher traction and a smoother feel through corners. The rear arm mounts were redesigned to use square composite bushings (as used on T4 and XB4 cars). The square eccentric bushings keep the vertical adjustment of the inner hinge pins from previous NT1 models, and add pin-width tuning to broaden roll centre and geometry options. A narrower holder allows the arms to be positioned closer together to further increase rear-end traction.
