CUSCO's LCA for the 2015 WRX, WRX STI, and 13+ FRS / BRZ / 86 feature a pillow ball joint and are designed to secure traction in drifting and stability during acceleration under high speed cornering. Most effective when fitted with racing tires or bigger than production size tires.

These arms allow for adjustment of camber in the rear of the vehicle. This is essential for lowered vehicles or race prepared vehicles.
