The XRAY 301208 T4'20 3.0mm Graphite Bumper Upper Holder Brace is designed to reinforce the top end of the T4 2020 chassis. Manufactured from 3.0mm graphite, it pairs with the existing top composite or graphite upper holder to improve structural support while keeping mass low.
Positioned to contact the bulkhead on heavy hits, this brace helps move crash energy into the bulkhead rather than concentrating it on the main chassis rails. That load distribution helps reduce the chance of chassis damage during track incidents.
