Powerflex Lower Engine Mount, Fast Road Mini R50, R52, R53

£167.94£184.74

An anodised CNC-Machined 6082 Aluminium mount pre-fitted with polyurethane bushes, for a true bolt-off, bolt-on replacement, with no pressing or assembly required. This Road Series mount provides a 100% increase in overall stiffness over the original voided mount, using a combined Purple 80A durometer small bush; and a 2-piece design large bush with Purple 80A and Yellow 70A bush components. With a minimal increase in NVH, reduced wheel hop and a more direct transition of power to the road, it is suitable for standard and mildly tuned vehicles and would be considered as the next step upgrade to our PFF5-107 and PFF5-120 offerings. A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine and chassis. The harder the material used, the greater the NVH transmitted.

WHY POLYURETHANE SUSPENSION BUSHES?

 

Time to do some sums…

WHY POLYURETHANE SUSPENSION BUSHES?Polyurethanes have been with us since the late 1930s, however, recent advances have now made it possible to engineer very special properties into this exciting material.

Suspension bushes are some of the most highly stressed components fitted to a motor car. They undergo enormous strains and in the most arduous of conditions with no maintenance or lubrication.

The material they are manufactured from is a rubber compound containing natural products that 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 in turn causes accelerated tyre wear, braking instability, and poor handling. This is the single biggest reason you can instantly tell the difference driving a three-year-old car compared to a showroom new one. However, even new cars will benefit from POWERFLEX bushes because of the superior design they offer much more effective control of the suspension components to a much greater extent than normal rubber items.

With the technological advances in this material, it has been possible to overcome the common problem associated with harder bushes which is increased noise. By correctly engineering the polyurethane compound, bushes can be made 25-30% stiffer than new rubber items but with exactly the same noise absorbing properties.

  • POWERFLEX bushes make sense.
  • POWERFLEX for improved performance.
  • POWERFLEX for increased safety.
  • POWERFLEX for prolonged tyre life.
