The XRAY 303768 Aluminum Chassis T-brace is a precision part for the X4 2022 series, machined from Swiss 7075 T6 aluminum. It is intended to increase rear traction and add controlled stiffness to the chassis, while still allowing targeted flex adjustments. Changing screw placement lets you dial steering balance to match your driving style.
Fitting this XRAY T-brace to the X4 helps the car stay composed at speed by improving rear grip and chassis control. The added stability makes it easier to carry speed through corners with reduced rear step-out.
The T-brace also functions as a tuning aid for chassis flex. By altering which screws are installed, racers can tune the steering feel toward crisper turn-in or a more forgiving, balanced response.
