The XRAY 302133-S X4 CFF Carbon-fiber Fusion Upper Arm is crafted to help drivers extract more traction on slick tracks. Using premium graphite with a softer composite outer layer, this suspension arm boosts lateral grip and responsiveness without adding unnecessary mass.
This arm features an inner carbon fiber plate whose thickness determines how stiff the assembly will be, while the composite surround controls flex behavior. That engineered combination delivers repeatable handling and predictable rebound when pushing corner speed.
Designed primarily for low-traction conditions, fit this soft arm in the front right and rear left locations of the X4 chassis to tune balance. Be aware that the softer construction trades some robustness for increased compliance.
