The XRAY 301208 T4'20 3.0mm Graphite Bumper Upper Holder Brace is made to strengthen the top mounting area of the T4 2020 chassis. Fabricated from 3.0mm graphite, it mates with the existing composite or graphite upper holder to add stiffness without a big weight penalty.
This graphite plate sits to engage the bulkhead on heavy contacts and routes collision forces into the bulkhead structure, helping to limit stress on the main chassis. That behaviour makes it a sensible fit for race-day drivers and hobbyists who push their cars hard.
