GT/Xb8 Carbon Upper Plate for Rear Lower Arm, XRAY 353195  [XR-353195]

Carbon upper plate for rear lower arm

This carbon upper plate reinforces the rear lower suspension arm on GT/Xb8 scale cars, intended for RC use only. When paired with a lower carbon stiffener it increases lateral and torsional rigidity of the lower arm assembly, reducing unwanted flex under high load.

The result is a rear end that feels more consistent through turns, improving traction at mid-corner and helping drivers carry more speed on medium to high-traction layouts. This upgrade is focused on riders who want predictable rear behaviour without overhauling the chassis.

Fitment is straightforward but requires standard rear suspension removal; use the existing lower arm attachment points and confirm screw fitment before final torque. After fitting, recheck suspension geometry and fine-tune gradually.

For setups on higher-grip tracks this plate provides a simple, non-invasive way to raise lower arm rigidity and sharpen corner performance while keeping baseline chassis geometry intact.
