BMW Suspension Bushings & Mounts

For someone looking for superior performance and longevity these sealed monoball bushings are the best upper thrust bearing you can buy for an F22 2-series or F3X 3/4-series. The advantage of a monoball bearing is that it will not deflect under load. All of the rubber bushings move in all sorts of directions and that changes your alignment, especially when used with big brake kits or when driven hard. The condition worsens as the bushing wears out. The Dinan monoball sits in a CNC machined aluminum housing which has zero deflection. The monoball allows complete freedom of movement but only at the desired angles. What you get is superior steering precision, better handling from more consistent alignment, and almost infinite bushing life. And thanks to the inner liner and sealed rubber boots there's none of the extra noise or reduced service life of fully solid race bushings. 

We strongly advise using these with new control arms. BMW recommends that the bushings be replaced only once per set of control arms. So if your thrust arm bushings have been replaced already then we do not recommend re-using the arms. The other reason is that the aluminum arms stretch over time which will make the bushings loose inside the arm. Other manufacturers recommend filling the stretched arms with paste but replacing the control arm is the better solution.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere.

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.
