Powerflex Front Arm Rear Bush Caster Offset BMW F4X, F52, F39
£171.48 – £188.28
PFF5-1302G is a CNC-machined mount with polyurethane bush providing approx 1 deg of caster offset to improve in-corner camber gain without compromising straight-line traction. It has a knurled body to retain grease and allow free rotation of the bush, preventing torsional twist in the bush material, aiding performance, reliability and increasing longevity. PFF5-1302G has a knurled pattern body to retain grease and allow free rotation of the bush. This prevents torsional twist in the bush material, aiding performance, reliability and increasing longevity.
WHY POLYURETHANE SUSPENSION BUSHES?
Time to do some sums…
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.
