Aluminum reduced suspension system holder for the FRONT associated with front suspension system. Redesigned to move the internal pivot location closer to the car center permitting to make use of longer and smaller suspension arm alternatives and brand new suspension geometry. The narrower design increases rear traction. The aluminum suspension system holders feature built-in Suspension Settings (I.S.S.) that allows for quick & easy suspension system geometry set-up. Machined from premium Swiss 7075 T6 aluminum and black coated. Using eccentric suspension bushings placed into aluminum suspension blocks, and extra suspension system shims, the XB4 suspension system geometry could be entirely modified.
