XRAY 353195 - GT/Xb8 Carbon Rear Lower Arm Upper Plate (2)  [XR-353195]

Rear lower arm carbon upper plate

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.

Reduced arm flex produces a freer-feeling rear suspension that helps maintain traction through cornering while preserving predictable handling balance. The part is aimed at setups for medium to high-traction tracks where extra arm stiffness can translate into improved corner speed without destabilizing the chassis.

Installation requires standard rear suspension disassembly and reassembly; use the existing mounting points on the lower arm and verify fastener fit before final tightening. Changes in arm stiffness will affect suspension tuning, so check toe, camber and shock settings after fitment and adjust incrementally.

For racers tuning rear-end feel on medium to high-traction surfaces, this plate offers a direct way to increase lower arm rigidity and refine corner entry and mid-corner behaviour without major chassis changes.
