XRay Rear Lower Suspension Holder RF – XR343710

The XRay Aluminium Rear Lower Suspension Holder – Front (RF) (part XR343710) is a precision CNC-machined upgrade made from premium Swiss 7075‑T6 aluminium. It installs at the forward edge of the rear bulkhead and mounts directly to the chassis to enhance traction and make the car easier to drive.

Designed for strength and consistency, this RF holder provides a more durable mounting point for the rear suspension arms. Thanks to the updated mounting system, the arms move very freely, delivering higher traction and a smoother, more connected feel through corners. Even after hard crashes, the suspension geometry remains unchanged for reliable handling run after run.
