The Ground Control Rear Articulating Spring Perch makes life a lot easier at the track or whenever on-the-fly height adjustments are needed. The GC perch is an adjustable-height rear spring perch for the stock (upper) location on the rear of E82, F22, E9X, F3X, F8X, and G8X lower control arms. Adjustable perch means you can now corner weight your car while it's loaded on a scale platform - or even more easily when the car is on a lift. The spherical bearing design also assures the spring load remains vertical through the fully-arced range of motion during rear suspension movement.
Priced per pair. Available for 2.25" or 2.5" ID springs. 60mm springs will use 2.25". These will raise the rear ride height so you may need a shorter rear spring to achieve your desired ride height. Recommended for race use only.
