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.

Following extensive development and testing, Verkline is thrilled to introduce this cutting-edge rear subframe to the global automotive community. Crafted with precision and performance in mind, this subframe is the result of a comprehensive process that includes 3D laser scanning, CAD development, Finite Element Analysis (FEA) testing, and rigorous road trials. Key Benefits: Significant Weight Reduction: This lightweight subframe is 6.5 kg lighter than the OEM rear subframe, resulting in a remarkable 33% reduction in weight on the rear axle, delivering enhanced vehicle performance. Optimized Rear Final Drive Position: The rear final drive has been strategically repositioned 10 mm upward to alleviate stress on the C.V. joints. This adjustment safeguards against premature joint wear, especially when lowering the vehicle. Robust Mounting: The subframe has eliminated rubber mounts in favor of a single, bolted mounting position. This design choice prevents rear subframe shifts during high-load situations. Bump Steer Adjustment: The subframe is equipped with additional bump steer adjustment capabilities, enabling users to fine-tune the bump steer by adjusting the rear toe link pickup point up and down. Polyurethane Mounts: Factory rubber mounts have been replaced with race car-grade black polyurethane mounts, substantially reducing movement during torque transfer and improving drivetrain performance. Key Features: Ample Underbody Access: The subframe provides more space for underbody access, facilitating easier maintenance and upgrades. Enhanced Chassis Rigidity: Constructed with a tubular frame design using T45 tubing and S355 metal sheets, this subframe bolsters chassis rigidity for superior handling. OEM Compatibility: Verkline has retained the OEM mounting points for wishbones, sway bars, brake lines, exhaust systems, and headlight range sensors, ensuring a seamless plug-and-play installation. Quality Assurance: Designed, fabricated, validated, and tested in Poland, each piece undergoes rigorous inspection by trained staff. Weldings are rigorously checked for cracks, and the entire product is meticulously examined before shipping. Aesthetically Pleasing: In addition to exceptional performance, the subframe boasts a visually appealing design that complements the vehicle's overall aesthetics. Included Components: Pre-assembled rear subframe powder coated in black (other color options available for an additional cost). Set of steel lockout wishbone positioning shims (24 pcs.) for precise Toe Link positioning and bump steer adjustment. Bolt and nut kit for easy installation of Toe Links (Zinc plated, grade 10.9). Set of steel lockout wishbone positioning shims (8 pcs.) for precise Camber wishbones positioning. Race polyurethane mounts for the rear differential.
