Ground Control Rear Articulating Spring Perches - E46

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 location on E46s. Bottom-adjustable 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 - does NOT include upper nylon cones to locate springs, which we highly recommend.

2.25" ID springs only. 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.
