E36/E46 3 Series Rear Articulating Spring Perch/Weight Jack

This new Ground Control piece makes life a lot easier at the track. Recommended for race use only, this is a rear adjustable height spring perch for the stock location. Bottom adjustment means you can now cornerweight your car as it is loaded on a scale platform - or much more easily in the air. The spherical bearing design also assures the spring load remains vertical through the full arced range of motion of the rear suspension movement. 

Priced per pair of rear adjusters, includes upper nylon cones to locate springs. 2.25" ID springs only.
