XRay Aluminium Quick Roll-Center Holder 4.9mm H1+H2

Refine your touring car’s roll-centre tuning with the XRay Aluminium Quick Roll-Center Holder 4.9mm – H1 + H2 (XR303035). Supplied as a matched pair, these CNC-machined high‑grade aluminium holders sit 1mm higher than the L1 + L2 (lower) option, allowing the chassis to roll more. They can be installed at either the front or rear to fine-tune steering response and stability, especially on high‑traction tracks.

Features

• 4.9mm Quick Roll-Center holders
• Matched pair marked H1 & H2
• Raises roll centres by 1mm versus lower holders
• CNC-machined high-grade aluminium
• For either front or rear suspension

Tuning Notes

• Front: makes the car turn easier; on high-carpet traction it decreases in‑corner steering and helps to prevent traction rolling.
• Rear: increases corner steering and speed.
