Extra soft arm with thinner carbon generates more mechanical traction of the car and improves side traction. Recommended for very low & low traction asphalt and carpet tracks. The softer arm is slightly more fragile. The upper arm shape conforms around the inner shock position for proper clearance without compromising strength and improve steering and both forward traction and lateral traction. This design improves durability and eliminates radial play for maximum precision and control from the upper arms. The upper arms are made using a CFF™ - Carbon Fiber Fusion, for outstanding handling. This upper arm will fit on the front right, as well as the rear left side of the car. Extra soft hardness.
