BMW Suspension Parts for BMW E46 M3 S54 (1999-2005)

The Powerflex Rear Lower Control Arm Inner Bushing for BMW E36 and E46 3 Series, Z4, and X3 is designed to provide a significant upgrade over the factory rubber bushings. By using high-performance polyurethane, these bushings enhance the stability, responsiveness, and overall performance of the rear suspension system.

Key Benefits:

1. Enhanced Handling Performance: The stiffer polyurethane material reduces flex and improves the rigidity of the rear control arm, resulting in better handling and stability during cornering and aggressive driving maneuvers.
2. Durability and Longevity: Unlike standard rubber bushings, these polyurethane bushings are engineered to withstand wear from road debris, oil, and temperature fluctuations, ensuring they maintain performance over time.
3. Improved Steering Feedback: With reduced movement and play in the rear suspension, these bushings provide a more direct connection to the road, enhancing steering responsiveness and driver control.
4. Precision Fitment: Specifically designed for BMW E36 and E46 3 Series, Z4, and X3 models, these bushings ensure an accurate fit and easy installation, making them a straightforward upgrade for enthusiasts.

These bushings are ideal for BMW owners looking to improve the handling dynamics and durability of their vehicle’s rear suspension, suitable for both daily driving and performance-oriented applications.

This is a NEW replacement polyurethane bushing used in our E46 M3 Front Street Camber Plates. This is a custom-manufactured part for Turner Motorsport, made with our own specifications. Replacement is straight-forward but does require the camber plates to be removed from the car. Price is for each bushing.

This item fits the following BMWs:
2001-2006 E46 BMW M3 with Front Turner Street Camber Plate

Here at Turner we understand the importance of an upgrade that will get the results you need on the track and still be tolerable on the drive around town. When it comes to control arms on the track, making them as stiff as you can (usually using solid mounts) is the best way to increase your driving precision by eliminating the deflection of rubber. The next best thing to create a balance would be to stiffen up the control arm with polyurethane, giving you the option of a more stock like feel with 80a or closer to the solid feel with 95a durometers. These poly bushings will give your control arms a direct connection between your suspension and the body of the car eliminating the slop felt under take-off and braking so you feel more in control of your vehicle.

*Featuring a delrin sleeve to eliminate heat deformation and premature failure.

This item fits the following BMWs that use a centered-style bushing:

The rear springs on the 2001-2006 E46 M3 models have a chronic broken spring problem. If it hasn't happened to you yet it will. Springs are nothing more than exposed steel and they rust easily. After a while a section of the spring actually breaks off.

A broken spring is very dangerous - the spring is no longer mounted correctly in the suspension and it cannot support the weight of the car, especially when cornering. The ride also suffers as the suspension is no longer able to absorb the bumps and impacts from the road. Aside from a visual inspection of the spring itself you might notice a clunking sound or banging noise coming from the front or rear. An inspection of the noise should also include other related items in the suspension: bushings, ball joints, links, mounts, etc. We also recommend replacing the rubber spring pads on the top and bottom of the spring because they lose their shape over time.

The factory BMW springs sell for $140+ each. We sold and replaced enough while working in New England that we were able to get a strong grasp of the issue and come up with our own springs that are an improvement over the factory springs in every way. These springs are made in Germany using high grade spring steel that is then shot-peened for longer life and powder-coated for protection. These are the same height as the stock replacement BMW springs which makes them a direct replacement.

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.

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.

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

Lowering your BMW does wonders for appearance and handling, but it also changes suspension geometry in ways that can hurt performance. As ride height changes, angles between the sway bar, control arms, and axles shift, which can cause binding, poor fitment, and added stress on the factory fixed-length end links. This is especially noticeable on cars equipped with coilover suspension, where slight height differences side to side can preload the sway bar and lead to inconsistent handling.

Our team of dedicated BMW enthusiasts set out to address this common issue with Adjustable Rear Sway Bar End Links. Designed with performance in mind, they offer a fully adjustable range from 100mm to 120mm, helping eliminate preload, restore proper suspension alignment, and improve overall sway bar function. Constructed from high-quality billet aluminum, these end links are built to outlast the factory cast components and are finished with a black anodized coating for excellent corrosion resistance. Laser-etched wrench size markings allow for quick, easy adjustments while installed on the vehicle. Unlike the factory design, these end links use spherical rod ends at the control arm for increased responsiveness and a more direct handling feel. These end links feature a bolt-through bushing design, which is compatible with most adjustable aftermarket sway bars. Mounting hardware is included for easy installation.

Features & Benefits:

Adjustable from 100mm to 120mm Strong 6061-T6 billet aluminum construction Black anodized finish resists corrosion Spherical rod ends improve response and handling feel Polyurethane bushing with knurled bore helps retain grease Fits most aftermarket sway bars with bolt-through attachment Laser-etched markings for quick and easy adjustments
