XRAY 303180-M X4 Right Rear Lower Arm CFF Carbon-Fibre Edition  [XR-303180-M]

Inspection Notes for the XRAY 303180-M X4 Arm

The XRAY 303180-M X4 CFF Carbon-fiber Fusion Rear Lower Arm blends a carbon layer with a composite shell to deliver tuned flexibility at the rear. This right-side arm is aimed at drivers chasing consistent lap times on asphalt.

Bonded Carbon-Fibre Composite Method

XRAY's fusion process joins a carbon-fibre plate to a composite base to create a single-piece arm that resists fatigue while allowing controlled movement. The result is a strong yet compliant component.

Asphalt-Ready Medium Flex

Medium flex arms give a softer feel than hard variants, improving tyre contact on smooth tracks and aiding traction in higher temperatures. They are a good choice for drivers seeking a balanced rear end.

Engineered Graphite Components

Produced from quality graphite and composite blends, the CFF arm is compact and low mass, with precise production tolerances that help preserve setup accuracy across race weekends.
