XRay X4 CFF Carbon-Fiber Fusion Front Lower Arm - Hard - Right

The XRAY X4 CFF Carbon-Fibre Fusion Front Lower Arm – Hard – Right (XR302180-H) fuses a carbon fibre plate with a composite outer using XRAY’s advanced manufacturing process. This creates a single CFF suspension arm that is super lightweight, compact, and engineered for consistent on-track performance.

The thickness of the inner carbon plate defines the arm’s hardness and flex, while the composite material around it controls flex and rebound for a uniform feel from corner to corner. The Hard hardness front lower arm is recommended for carpet tracks and some high-grip asphalt, offering the most consistent handling and making the car more free (less stopping) in corners compared with M arms. This version fits the right side of the car.
