Time to do some sums...

Polyurethane has been with us as a specialised plastic for some thirty years. 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 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 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 their 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. FITTING POWERFLEX BUSHES:

We sometimes receive comments that people feel they are not a competent enough mechanic to fit Powerflex parts and it is a job for professionals.

Our team work very hard to ensure our bushes are designed, in general, to be fitted by a home installer without the necessity for hydraulic presses and special tools.

However removal of the old parts is often more daunting than fitting of the new.

CASTER What is it? – Pretty much always positive on normal cars, it is the pivot angle described by the front suspension.

The tyre contact point is behind the theoretic pivot point. Like the contact point of a shopping trolley caster wheel is behind the pivot point.

What does it do? – Positive caster gives straight line steering stability and causes a self-centring action to the steering.

By increasing the caster on a road car we can improve the stability and improve cornering grip due to a further effect on most cars of the caster increasing the dynamic camber during cornering.

ABOUT CAMBER

Put simply, negative camber is most popular on modern cars and is where the bottom of the wheel is further “out” than the top looking from ahead and compared in the vertical plane.

Older race cars ran positive camber to reduce steering effort and due to their narrow tyres it did not have the effect that it would on cars with modern wider tyres. Whilst we can think of no reason for needing positive camber now, reducing negative camber can be very important.

We manufacture a number of parts to allow camber to be modified on suspension systems where no modification is possible, and it is not always about increasing camber.

Increasing negative camber may be beneficial to improve front end grip and turn-in on a track biased car.

However it is not always about performance. Camber adjustment can be needed to correct an imbalance from side to side to reduce tyre wear, and lowering a vehicle can increase negative camber to the point of increasing tyre wear. (A very common problem on the VW Transporter, solved with these bushes)

We manufacture a huge range of parts for many different cars that allow camber adjustment or correction.

From camber bolts that allow adjustment on fixed McPherson strut suspension, to clever on-car adjustable bushes like these Alfa ones, developed to correct a common geometry issue. Or these Porsche bushes, adjustable to allow precise geometry tuning.

Don't forget our handy little magnetic camber gauge too.

Honda S2000 Front Lower Arm Rear Compliance Bush and Eccentric Caster Adjustment Kit

The front lower arm rear complaince bush on the S2000 is now a common bush to fail.  The rubber bonding fails causing a lot of geometry change as the bush allows too much movement.

With the introduction of PFF25-203 we have vastly improved the performance and reliability.

The design features a dual rate polyurethane ball operating in a polyurethane race encased in a zinc plated outer shell. The centre of the bush is stainless steel.

The principle advantage of this special design is that the radial compliance rate can be high and therefore geometry control is enhanced greatly. But with almost friction free operation as the suspension moves. Like a uniball but better.

In addition to the bush we have also manufactured an eccentric mounting kit PFF25-203G to go with the bush. The kit features a stainless steel eccentric centre location pin and a 10.8 spec. high tensile zinc plated mounting bolt. It is almost impossible to remove this bush without detroying the Honda eccentric part because it rusts into the bush, so this stainless steel kit solves that issue as well, and all for the same price as the Honda part.

New Product
PFF85-704 Engine Mount Insert fits vehicles from the middle of 2008 in the VAG group using the PQ35 platform.

The insert fills the voids of the original bushes so limiting engine movement, improvements include more effective power delivery to the wheels and crisper more defined gear changes, along with less stress for the exhaust down pipe.

VAG changed the design of the voiding around the middle of 2008 for earlier cars our insert PFF85-504 will fit, please check the diagram to select the correct insert.

We have made the insert in 3 versions :-

PFF85-704 made in Yellow Shore A 70 and is suitable for fast road applications.

PFF85-704R made in Red Shore A 65, more suitable for diesel engines where using the fast road material can cause too much NVH (Noise, Vibration, Harshness).

PFF85-704P made in Purple Shore A 80 these are suitable for higher powered engines, track and competition cars, NVH will be more noticeable as the material is stiffer but will allow less movement.

Range Updated
Caterham Seven

We have recently updated our applications for the Caterham range of Sevens including DeDion with Watts linkage, DeDion without Watts linkage and the CSR model.

The bushes that we have designed for this unique vehicle are, in themselves, unique.

This car is one of the lightest and finest handling cars on the planet, with many owners spending thousands on spring/damper units trying to achieve perfect handling.

However we have always been concerned that whilst the dampers themselves feature 21st century technology the bushes are from a different era. The design of the factory bushes are an inner and outer steel tube with bonded rubber acting as the isolator. The problems that arise from this design are two-fold. The rubber bond breaks allowing the centre of the bush to float fore and aft, however if the bush is in good condition it acts like a spring. Multiply that spring effect by four on each corner and the fact that the spring rate changes as the bush gets older means that the damper does not have total control of the suspension.

Of course a spherical joint is the precision answer but not acceptable for the road.

This is why Powerflex have developed the frictionless bushes for this car. With the precision of a spherical and the performance of polyurethane. The bushes feature a frictionless PTFE lined bearing and polyurethane outer which doubles as a weather seal and vibration damper.

All bearing parts are manufactured in stainless steel/PTFE and like all of our products carry a life time warranty.

Powerflex Exhaust Mounts
Working in conjunction with our raw material supplier we have formulated an innovative new material, which after months of testing, has proven to be ideal for Powerflex high temperature exhaust mountings.

             The range is the same
                      The design is the same
                              The price is the same
                                       The performance is improved
                                                The colour is new

Powerflex Exhaust mountings have been developed to give between 25 and 30% less movement under load. This is especially useful for modified or competition vehicles with aftermarket exhaust systems.

We describe these as universal mounts which are not designed for any specific vehicles. We have found that it is almost impossible to state that a particular aftermarket exhaust when fitted to a particular vehicle will require a specific mount. Therefore we list dimensions and use images to help you choose the ideal mount for your application.

Subaru Impreza including WRX and STi models, chassis codes GH 10/07-on and GR 02/08-on.

Powerflex is proud to announce that we have developed a full range of suspension bushes for one of the worlds most iconic modern performance cars.

  

Whilst developing our range of Powerflex low compliance polyurethane bushes for the Impreza we have been working on a new range of Geometry Adjustable bushes to allow on-car adjustment of camber and caster on certain bushes as well as Anti Lift geometery where possible.

For the front of the Impreza the Front Arm Rear Bush PFF69-502G has revised ANTI-LIFT geometry and on-car CASTER adjustment  allowing +/- 0.33 degrees of adjustment. The rear bushes PFR69-510G & PFR69-511G has been engineered to give on-car CAMBER adjustment with a range of +/-1.0 degree.

All these bushes come with adjustment tools for ease of adjustment when carrying out alignment settings.
