GTX 2026 Carbon Center Mount Rear Brace (Short, Flat Chassis) - XRAY 354258  [XR-354258]

Compact GTX rear center brace

This carbon rear top deck is a compact brace that links the center 2-speed assembly to the rear aluminum brace mount on compatible GTX 2026 flat chassis layouts. Its short form factor is intended to influence rear chassis flex characteristics without adding unnecessary mass, helping to stabilize the drivetrain and maintain consistent traction through variable track conditions.

The part is precision machined from carbon fiber to offer a balance of stiffness and light weight. In practice the brace functions as a tuning lever, shifting rear flex bias to produce more predictable handling on corner exits and steadier load transfer under acceleration. The brace is positioned to minimize drivetrain twist between the center gearbox area and the rear brace mount, improving repeatability lap to lap.

Installation is straightforward for experienced builders familiar with GTX-series rear assemblies. Fitment requires correct alignment between the center 2-speed mount and the rear aluminum brace mount; check mating surfaces for flatness and ensure hardware seats evenly. Do not overtighten fasteners, and verify drivetrain rotation after installation to confirm there is no binding introduced by misalignment.

For GTX 2026 builders seeking a compact, stiff carbon link between the center gearbox and rear brace mount, this short rear brace provides a targeted way to tune rear flex and sustain drivetrain stability without significant weight penalty.
