Our CNC machined e46 & e46M rear subframe bushings are designed to replace the OEM subframe bushings and stop the rubbery flex that can affect handling and could damage the rear subframe or even the chassis. When the e46 is driven hard on the street & the track, the rear subframe is exposed to substantial twisting forces. With our bushings, you won't have to worry about any more flex in your subframe; your rear alignment will stay in check during hard cornering, braking, and acceleration. We use UHMW in all our suspension bushings. It is a self-lubricating Polyethylene that has almost zero deflection yet also absorbs vibration. It will outlast other types of rubber or urethane bushings. We CNC machine them to the correct tolerances for a smooth hassle free install.
