Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) factory rubber subframe bushings were engineered to provide a balance of control while keeping the ride quality soft and supple. As a factory bushings age, they become brittle and begin to harden. When this happens the bushing will actually shrink and allow excess play, or movement in the subframe. This is typically felt by a sudden jerk or "thunking" noise under acceleration and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushings with full polyurethane this play is eliminated since the subframe is being held in place by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering and acceleration inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver. 

Engineered to perform, Powerflex performance polyurethane bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

Any subframe work or reinforcement project on the rear of the E46 M3 should include a new set of subframe mounts. It's the worn rubber bushings that contribute to failed rear subframes on the E46 (but not the only reason). As the rubber gets worn, there is more flex to the mount. This flexing is then transferred to the sheetmetal in the floor where the spot welds will pop and the sheetmetal will crack. Additional force coming from stiffer suspensions and stickier tires will only increase the flexing of the mounts/chassis.

Of course, stiffer mounts would help prevent this problem but with a stiffer bushing comes ride harshness, vibration, and additional noise. Our engineers and technicians recommend replacement with the factory rubber bushings (along with the appropriate reinforcement of the floor). The rubber bushings help isolate bumps and impacts and are quiet. They are also a perfect fitment and require no maintenance.

This item is a set of 4 Original BMW rubber subframe mounts. Individual part numbers - 33 31 2 283 573 (left front), 33 31 2 283 574 (right front), and 33 31 2 283 419 (left and right rear, x 2).

Applications:
2001-2006 E46 M3, M3 CSL coupe, convertible
2007-up Z4 M Roadster, M Coupe
