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

ECS Polyurethane Subframe bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Featuring 95A durometer polyurethane, ECS Polyurethane Subframe bushings are 25% stiffer than street bushings. Engineered to perform, ECS Polyurethane Subframe bushings offer a supreme level of control, while still maintaining enough comfort for the street. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure.

Key Benefits:

95A Polyurethane isolator reduces unwanted drivetrain movement while still allowing for an aggressive yet streetable driving experience.

Polyurethane bushings reduce subframe bushing deflection versus stock rubber bushings while keeping vibrations associated with such modification to a minimum.

Poly formulation and durometer, profile, and loaded surface area designed to minimize stress concentrations to stay within acceptable compressive strain limits of the material

Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) ECS Polyurethane Subframe bushings were engineered to provide a balance of control while making ride quality more responsive, yet still streetable. As a factory bushings age, they become brittle and begin to harden and crack. 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.

Macht Schnell's aluminum bushing kit will breathe new life into aging 1M's and M3's, affixing the car's rear subframe and differential to the chassis. Rubber subframe bushings in the E9x M3 and E82 1M from the factory are soft, and yield under hard driving resulting in ever-changing suspension geometry and alignment specs. By limiting the movement of both the car's subframe and differential, these solid bushings will give the rear of the car a tremendously planted and confident feel.

The subframe and differential mounting point is the heart of the rear suspension in an E34. When they move, so do all of the rear suspension mounting points. Replacing the stock rubber subframe and differential bushings with UHMW will limit drivetrain and suspension movement and keep your car’s suspension geometry the way it’s supposed to be. They will last longer than the original rubber and do not 'wind up' under load/unload, transferring more power through the axles to the wheels. Recommended for street or race use. Set of 2 subframe bushings.
