X4F Front Chassis Brace for Tunable Flex - XRAY 303766 Swiss 7075 T6  [XR-303766]

Adjustable front brace for precise X4F handling

This aluminium front chassis brace is an RC-scale accessory designed to alter the flex characteristics of the X4F front chassis area. Mounted across the front suspension section, the brace gives precise control over how the chassis transfers load and reacts to steering inputs without changing other hardware.

Installation supports multiple screw configurations so you can vary how the brace couples to the chassis. Settings range from no connection for maximum forward traction, to full connection for increased steering responsiveness, with intermediate options to balance corner speed, steering feel and overall drivability. Adjustments can be made trackside using standard hex screws and a hex driver to test settings under different traction conditions.

The part is machined from Swiss 7075 T6 aluminium and finished with a black anodize. As a dedicated RC part for the X4F front area, it is intended for tuning responses on various track surfaces, from low-traction outdoor asphalt to high-traction indoor carpet.

For drivers who tune chassis flex as part of setup work, this brace provides a controlled, repeatable way to influence front-end behaviour without swapping major components.
