XRAY 302143-S X4 CFF Soft Carbon-Fiber Upper Arm - Grip Enhancement  [XR-302143-S]

Better Corner Bite with the XRAY 302143-S Upper Arm

The XRAY 302143-S X4 CFF Carbon-fiber Fusion Upper Arm is aimed at drivers improving mid-corner stability and side traction. Combining a carbon fiber center with a softer composite shell, this arm helps deliver a more forgiving contact feel on low-traction surfaces.

Engineered Flex for Consistent Turns

XRAY's fusion technique produces a suspension arm where the carbon inner plate sets structural behaviour and the softer composite provides controlled give. The result is steadier handling through a range of corner speeds without abrupt snap-back.

Specific Application and Care

Intended for the front left and rear right spots on X4 series cars, the soft hardness suits very low to low traction conditions. Keep in mind the softer composition can be less damage tolerant, so inspect after heavy impacts and consider spare arms for race days.
