XRAY 303181-H X4 Carbon Fiber Fusion Rear Left Lower Arm - Hard Carpet Tune  [XR-303181-H]

Refined handling upgrade for the X4 rear arm

The XRAY X4 CFF Carbon-fiber Fusion Rear Lower Arm - Hard brings precise engineering to the left rear of your touring car. The design combines a carbon fiber plate with a composite outer section to deliver a measured balance of stiffness and controlled give.

Fusion build for repeatable response

XRAY uses a fusion method that bonds a rigid carbon core to a composite shell, producing an arm that resists unwanted flex while allowing consistent suspension movement. That balance helps maintain predictable handling over multiple laps.

Matched to carpet and high grip layouts

The hard X4 rear lower arm excels on carpet and high grip asphalt by reducing suspension deflection during corners, improving steering precision and lap consistency for drivers tuning for grip.
