GTX 2026 Flat Chassis Carbon Centre Rear Brace for Tuning - 354255 XRAY  [XR-354255]

Rear centre carbon brace - GTX tuning part

The XRAY 354255 carbon center mounting rear brace is an RC-scale top deck component engineered to pair with the aluminium center upper brace mounting plate #354290 to modify rear chassis flex. Precision machined from carbon fibre, the brace is designed to provide a controlled decrease in rear stiffness that can increase rear traction and deliver steadier handling where added compliance is desired.

Fitted at the chassis centreline, the brace fastens to the existing centre upper plate; combined with the specified aluminium plate the stacked arrangement alters the rear section's torsional response. This product is aimed at racers seeking a measurable tuning route to soften rear chassis behaviour on low-traction circuits without introducing extra mass from bulkier solutions.

From a setup perspective, the part changes the balance between chassis twist and suspension movement: a more compliant rear chassis allows the rear tyres to follow surface irregularities more effectively, improving rear bite on corner exit and aiding consistency across laps. Use the brace alongside shock, tyre, and swaybar setup changes to achieve the track-specific handling you need.

Select the XRAY 354255 when a controlled move to a more compliant rear is required; fit it with the #354290 aluminium centre upper brace and trial incremental adjustments on track to find the right balance.
