Powerflex Front Wishbone Rear Bush, Aluminium Outer Caster Offset BMW 3 Series E30, E36 & Z1, Z3 inc Compact, M3 & Z3M
£142.68 – £157.08
PFF5-5303 includes a CNC-machined aluminium outer shell with an eccentric offset bore, increasing caster by 6.5mm / 0.5deg, for better turn-in response and in-corner camber gain. By including the shell and reducing the amount of polyurethane material used, we have increased stiffness by a further 50% over PFF5-301 and PFF5-303, and a massive 250% over the standard OE rubber bush. The results are incredible, with minimal deflection under steering load and braking, whilst maintaining a balance of compliance and performance.
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.
