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

Hotchkis Sport Suspension products have been developed with strength, reliability, fitment, appearance, and durability all factored into their products to ensure that customers are never left unsatisfied. Suspension components are exposed to not only the elements, but also constant ever changing forces that will push the limits of any performance component to its breaking point if not built to a superior quality. This is especially true in vehicles with lowered suspension. Make sure your suspension is ready for any abuse thrown its way with Hotchkis Performance Sway Bars.

Performance sway bars allow you to take corners aggressively while still keeping the wheels firmly planted and reducing body roll, all without reducing overall ride quality. Hotchkis sway bars feature powder coated tubular steel construction for maximum durability and stiffness. Every kit includes the essential components needed for an easy installation and to ensure you get the most from your sway bars.

The Powerflex BMW E30 / E36 / E46 / Z3 / Z4 Rear Shock Mount – 10 mm is an advanced suspension upgrade designed to improve the rear shock performance in a wide range of BMW models. By replacing the factory rubber mounts with polyurethane, this mount ensures a more durable and performance-oriented suspension setup.

Key Features:

• Multi-Model Compatibility: Specifically designed for BMW E30, E36, E46, Z3, and Z4 models, this 10 mm rear shock mount is a perfect fit for vehicles with rear shocks that feature a 10 mm rod diameter. It offers seamless integration and performance enhancement across these BMW platforms.
• Polyurethane Construction for Enhanced Durability: Unlike OEM rubber mounts, which are prone to wear and degradation over time, these mounts are crafted from tough polyurethane. This material provides greater resistance to wear, oil, road contaminants, and high temperatures, ensuring a longer-lasting component that maintains its structural integrity.
• Superior Handling and Control: The stiffer polyurethane reduces the flex and movement that can occur with rubber mounts, providing more direct shock performance. This results in better handling, improved suspension response, and increased stability, particularly during aggressive driving or when cornering.
• Comfortable Ride Quality: Despite its firmer characteristics, the polyurethane shock mount is designed to absorb road vibrations and noise, ensuring that while your handling improves, you don’t sacrifice the comfort BMWs are known for. It balances performance and comfort, making it suitable for both daily driving and spirited driving.
• Quick and Easy Installation: Designed as a direct replacement for the stock rear shock mounts, this bushing allows for a straightforward installation process. No additional modifications are required, making it a simple yet effective upgrade for your BMW’s suspension.

This Rear Shock Mount – 10 mm is an ideal upgrade for BMW E30, E36, E46, Z3, and Z4 owners who want to improve their vehicle’s handling performance and suspension durability. The combination of enhanced strength and control with ride comfort makes it an excellent choice for both everyday use and more performance-driven situations, offering a long-lasting solution to rear shock mounting issues.

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.

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. 

Sway bars are an essential upgrade when trying to get the best handling capabilities out of your BMW. Stock sway bars allow for too much play and excessive body roll, not keeping the wheels as firmly planted as they should be. Whiteline offers their performance sway bar kits that are designed to improve your BMW's handling characteristics and come with upgraded polyurethane bushings as well.

This Whiteline 30mm sway bar gives you more grip, better handling, and better outright performance. Sway bar upgrades are one of the best dollar-for-dollar investments you can make, improving your BMW's handling dynamics without affecting the comfort or ride quality.

Want a race-spec rear shock mount but with the comfort of a factory bushing? This ECS rear shock mount combines the precision and articulation of a spherical bearing with the isolation of urethane bushings. The stainless monoball bearing is lined with PTFE lubricant and suspended in 80A urethane and housed in a hard anodized 6061-T6 aluminum mount. The spherical bearing is a better design than most rear shock mounts because it allows the shock to move and tilt without side-loading the shock shaft (which leads to premature failure of the shock). Most Genuine BMW and aftermarket shock mounts are not designed for shock angles and the stress that track or performance driving will put on the shock shaft. The ECS shock mount is properly designed to handle these loads. The internal bearing is also replaceable - it will be years before you have to replace the entire mount. The ECS mount is fully encapsulated to prevent the common shock mount failure of the stock mount design.

ECS RSM features:

• Maintenance free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation
• 80A polyurethane isolation bushings for NVH control
• Accommodates 10mm, 12mm, or 14mm damper shafts
• Fully constrained shaft mount makes RSM blow out impossible
• Hard anodized 6061-T6 construction
• Fully rebuildable design

* - the RSM comes with the BMW standard 10mm shock shaft bushings. 12mm is used on some performance shocks and 14mm is used on some true motorsport rear shocks.

A strut tower brace adds additional reinforcement to the front strut towers, tying them together for extra rigidity. This makes the whole structure stronger with less chassis flex. Handling and steering feel are improved with better turn-in and input with no downsides. 

The IRP adjustable strut brace bar is a high quality brace that is constructed of 100% steel for guaranteed reinforcement and prevention of flex. The brace bar is painted black to ensure corrosion protection.

Easily installed with basic hand tools.

*Does not fit convertible chassis"

There's finally an option to buy housings separate from the bushings, this way you don't have to live with the stress placed on the stock housings when pressing the old bushing out. The biggest benefit come in when there isn't already a pre-pressed in option for poly and spherical upgrades, this leaves the only option of pressing the old bushings out. Through out in-house testing when designing our poly and spherical upgrades we noticed that pressing the bushing out caused stress in some cases creating hairline cracks in the housing leaving it vulnerable to failure.
