Transform your E46 M3 into a track-ready machine while maintaining street-ability for the spirited enthusiast.

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. 

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. 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. 

This part fits the following BMWs:
2001 - 2006 E46

One of the most common issues with the E46 is that the subframe likes to tear away from the chassis. Fix this by welding in a Rear Subframe reinforcement kit.

• Includes all necessary reinfored metal plates
• Professional installation is required
• Suspension must be realigned after installation

Fits the following BMWs:
1998 - 2006 E46 320i 323i 325i 325xi 328i 330i 323ci 325ci 330ci M3

Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? 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.

These bushings replace the stock rubber bushings and offer a better driving feel, increased lifespan, and better wheel alignment.

Rubber bushing allow for a lot more movement and are more susceptible to wear and tear from spirited driving and harsh weather conditions. Polyurethane is much more resistant to wear and is stiffer, reducing the total amount of movement that would normally affect the alignment negatively.

H&R adjustable 25mm rear sway bar / swaybar for all 2001-2006 E46 M3 coupe and convertible. Includes bushings. Made in Germany.

• Reduces body roll
• Highest tensile strength available

H&R Sport Sway Bars are designed for drivers who desire improved handling without lowering or affecting ride quality. H&R Sport Sway Bars increase your suspension's roll stiffness or its resistance to roll in turns while maintaining ride comfort and dramatically increasing cornering control, lateral stability, and grip. A unique feature of H&R Sport Sway Bars are the smooth, machined-like forged ends that, for specific vehicles, allow for adjustability in stiffness giving you an unmatched level of precision and performance.

This item fits the following BMWs:
2001-2006 E46 BMW M3
2006-2008 Z4 BMW M Coupe/Roadster

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This, in turn, reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.
