Powerflex - Rear Subframe Front Bushing - BMW E46 M3 ^Sale

Rubber OEM bushings deteriorate with age.  Upgrade your bushings to Lifetime Warranty Powerflex bushings.  Bushings that won't increase noise or harshness while providing a lifetime of handling improvement and safety.

Polyurethane has been available as a specialized plastic for over thirty years. However, recent advances have made it possible to engineer very special properties into this exciting material. Suspension bushings are one of the most highly stressed components fitted to a motor car. They undergo enormous strains in the most arduous of conditions with no maintenance or lubrication. The material standard bushings are manufactured from is a rubber compound containing natural products which deteriorate with age. It becomes softer and more pliable, resisting the forces placed on it less and less. Therefore allowing more and more movement of suspension components and offering less and less control over the suspension geometry.

This causes excessive tire wear, braking instability and poor handling. This is the single biggest reason you can instantly tell the difference driving a three year old car and a new one. However even new cars will benefit from Powerflex bushings!  Because of their superior design they offer much more effective control of the suspension components to a much greater extent than normal rubber items.

Old and soft rubber bushings cause incorrect geometry and excessive tire wear as well as braking instability. With the technological advances in this material it has been possible to overcome the common problem associated with harder bushings, which is increased noise. By correctly engineering the polyurethane compound, bushings can be made 25-30% stiffer than new rubber items but with exactly the same noise absorbing properties.
