This is an optional XRAY "Short" Composite Rear Chassis Brace. Rear brace molded from medium-stiff composite mixture for optimal flex & rigidity, allowing the mounting of optional XRA353281 graphite inserts to reinforce the chassis brace to make it even stiffer (for high-traction conditions). Braces have a significant influence on chassis stiffness and flex, and have a great impact on handling under different grip conditions.
