Turner Motorsport BMW Suspension Bushings & Mounts

Modern BMW's are beginning to leave the performance derived handling and power delivery in the past as the demand for more comfort and features rises. The stiff suspension components designed around having the best driving experience from a luxury car has been left for the M models and replaced with soft rubber bushings and mounts. Unfortunately, this is a good move by BMW to support the masses.

The obvious approach was to offer products so the modern BMW can be upgraded into the car the enthusiast desires, superb handling, control, and a direct delivery of power to the rear wheels. When you upgrade to our Delrin subframe mounts you reconnect that power with almost zero negative feedback.

The added appeal to someone looking to take one of these machines on the race track is Delrin can be used when solid mounts are needed and aluminum is not an option with strict regulations found in??Grand-Am, BMW CCA, and other racing series.

Product features:

• Precision machined Delrin(TM) 150 bushings.
• Precision machined 6061-T6 aluminum inserts.?
• Class legal for any racing class that does not allow a solid subframe bushing.?

Performance Benefits:

• Eliminates subframe movement for more direct throttle and suspension? response.?
• Minimizes wheel hop due to subframe deflection and movement.?

If you're installing racing rear shocks with a spherical bearing end you will need this adapter mount for the top of the rear shock. Spherical or rod-end bearings are common on race shocks but they are somewhat universal and mounts are not usually included. We designed and engineered these mounts for our E9X M3 and E90 328i IMSA/CTSCC racecars. Our cacing upper shock mount is machined out of aircraft grade aluminum with a tough anodize finish and high grade hardware. Due to the wide variety of spherical bearings and rod-ends found on race shocks, the bushing kit is sold seperately (see chart for bushing sizes).

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.
