Turner Motorsport BMW Suspension Parts for BMW 3 Series E46 (1999-2005)

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. 

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

1999-2005 E46 BMW 323i 323ci 325i 325ci 328i 328ci 330i 330ci - not for xi models 
2003-2008 E85 BMW Z4 2.5i Z4 3.0i Z4 3.0si 

The E46 is by no means a very old car. But more and more E46s are seeing track use or being converted to all-out track cars. And the odometers aren't rolling backwards. With age, mileage, and hard use the chassis will develop weak points that threaten the overall integrity of the car. When suspension points and subframes start to rip from the car, it puts the driver and anyone else at a serious safety risk. Not to mention the obvious effects on the performance of the car. TMS has developed reinforcements for the most-common weak points in the E46 chassis. With these kits in place you can be sure that your car spends less time on a body rack and more time on the race track. Included in this package are all of the reinforcements we developed for the E46:
 

• front subframe
• front strut towers (not applicable for M3)
• rear shock towers
• rear camber arms
• rear sway bar / swaybar tabs (not applicable for M3)
• rear subframe

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

Factory bushings are more than adequate for street driving on the E46 M3. However, once the miles start to pile up, the bushings are meant to be replaced. Common side effects of worn factory FCABs include, but are not limited to the following:

• Steering wheel shutter when brakes are applied
• Wheel (and steering wheel) shimmy
• Mysterious and irregular tire wear
• "Overboosted" steering feel (very light steering)

Replacing with new factory bushings will return the factory feel. These urethane core bushings, however, offer something MORE. These bushings are designed to deliver performance that surpasses the stock E46 M3 bushing, while still allowing them to be used in everyday driving scenarios on public roads.

With the numerous delrin/urethane/hybrid replacement bushings in the market, we wanted to offer bushings that were not only effective, but simple. No clips, no washers, no multiple sleeves, and no "race parts in street cars". They have an aluminum outer sleeve with a replaceable, compliant urethane core that is serviceable and rebuildable. These urethane inserts prevent unwanted control arm deflection, while allowing noise/vibration/harshness (NVH) isolation -- a must on any bushing being used on a street driven car. And because of their compliance they remain very comfortable for daily use. But because they are a heavier-duty design than stock, these eliminate steering shimmy and wander, especially with the addition of big brake upgrades. They maintain BMW's original suspension geometry, and give your M3 a directly "connected" feeling with the front end of the vehicle. Perhaps best of all, these bushings are easy to install and are designed for longevity. Professional installation on suspension components is always recommended.
