Fall Line’s mono ball spherical bearing conversion kit transforms the rear suspension feel of the E46 M3. The factory rubber bushing is very large, and is prone to substantial deflection under load, as the M3 is put through its paces. Deflection of the bushing can create unwanted geometry change, steering wobble under braking, and even hysteresis of the thrust arm.

The bearing’s housing is precision machine from aluminum, to create a rigid part that allows for the M3’s thrust arm to move smoothly through its range of suspension travel. The improvement in steering and suspension feel is immediate and truly enhances the personality of the vehicle.
