Preorder now, ships in 3 months. CNC billet aluminum all spherical bearing front upper arms allow you to quickly add 1, 2, or 3 degrees of negative camber at the track just by jacking up the front, reaching over the tire and removing our triple stacked anti-shear spacer plates between the arm and outer joint (with CrMo pin) mounted with 4 bolts per side. This CNC machined masterpiece totally replaces the OEM FRONT UPPER CONTROL ARM ASSEMBLY allowing you to elimate the rubber inboard bushings and weak outer joint all at once with maintenance free spherical bearings for maximum response, feedback and control without the undesired spring force of rubber bushings acting upon your highly tuned aftermarket suspesnion. Super steering angle cleanance is built in a dynamic CAD model upon 3D scan data and CMM probed suspension geometry.
