GTX 2026 Rear Carbon Center Mounting Brace for Flat Chassis - 354255 by XRAY  [XR-354255]

GTX 2026 rear center carbon brace

The XRAY 354255 carbon center mounting rear brace is an RC-scale top deck element engineered to work with the aluminum center upper brace mounting plate #354290 to alter rear chassis flex. Manufactured from machined carbon fiber, the part provides a controlled reduction in rear stiffness that can increase rear traction and deliver more consistent handling where extra chassis compliance is required.

Fitment is at the chassis centerline where the brace secures to the existing center upper plate; when combined with the specified aluminum plate the stacked assembly changes the torsional response of the rear section. This component targets drivers looking for a measurable tuning option to soften rear chassis behavior on lower-traction surfaces without the weight penalties of larger add-ons.

From a setup point of view, the brace shifts the balance between chassis twist and suspension motion: softer rear chassis flex allows the rear tires to follow bumps more effectively, improving rear bite on corner exit and helping maintain consistent lap-to-lap feel. Use it alongside shock, tire, and swaybar tweaks to dial in the desired handling for each track.

Choose the XRAY 354255 when you need a deliberate move toward a more compliant rear end; pair it with the #354290 aluminum center upper brace and test incremental changes on track to find the optimum balance.
