For drivers wanting a firmer rear platform, the XRAY 303190 Graphite Rear Lower Arm Plate adds targeted stiffness to the suspension. The graphite component helps the rear end resist flex, improving directional control and steering precision on grippy surfaces.
The XRAY 303190 lets you match handling to conditions. Leave the stiffener out for a livelier rear when grip is low, then fit the plate as traction improves to tighten the rear and make the car easier to place through corners.
The plate mounts with four screws to the rear lower arms for a straightforward install. Its simplicity makes it easy to change between runs so you can fine tune balance during practice or race day.
