X4 CFF™ CARBON-FIBER FUSION REAR LOWER ARM - HARD - LEFT
The unique CFF suspension arms are an elegant engineering achievement that look great and perform even better on the track. Using XRAY's own newly developed manufacturing process, a carbon fiber arm and composite arm are molded together using a fusion process to produce a single CFF suspension arm. The benefits of the CFF arms are tremendous. The thickness of the inner carbon fiber plate determines the hardness and flex of the arm. The composite around the carbon helps control its flex and rebound, resulting in a very consistent feel from corner to corner. Machined and molded from premium-grade graphite and composite materials, the arm is super lightweight and very compact. Hard hardness of the lower suspension arms is recommended for carpet tracks and even for some high grip asphalt conditions. These will provide the most consistent handling and will make the car more free (less stopping) in corners, compared to when the M arms are used. This rear lower arm fits on left side of the car.
