The XRAY 303192 Graphite ARS Rear Lower Arm Plate is a precision component for T4 series models, designed to let drivers tune rear stiffness and improve stability under varying track conditions. The graphite plates offer a balance of stiffness and lightness for focused setup work.
Removing the plates increases rear compliance which can aid traction on dusty or low-grip surfaces. Fitting the plates increases stiffness to stabilise the rear end when grip is higher, improving cornering predictability.
These plates attach with four screws for quick fitting, allowing fast adjustments between practice sessions and competitive runs. They are well suited to drivers refining front-rear balance and steering feel.
