Power Flex Suspension Bushes For This BMW Z4.

Suspension bushes on all cars go through tremendous stress on a daily basis, some manufactures have got the design right and the bushes can last the life of the car whilst other manufactures just didn’t quite get there!

One of the problems with BMW’s in general is the front suspension bushes. Most of the BMW range suffer with the front suspension arm bushes either failing or being so worn that it causes the car to wander on the road whilst driving and can feel unstable when braking.

Replacing the bushes with either after market bushes or genuine bushes does sort out the problem, but with the condition of the UK roads and the fact that most BMW’s come with low profile run flat tyres the new bushes can be worn out within a couple of years.

The solution on this BMW Z4 was to fit some Power Flex nylon bushes, these bushes are mainly used in Motorsport but can be fitted to road cars.

Watch this video to see just how much movement was in the old worn bushes compared to the new Power Flex nylon bushes.

On the Z4 replacing just the lower suspension arm rear bushes was enough to transform the steering from a loose discouraging feel to a nice tight direct feel that a sports car should have.

A few Jobs from last week.

This beautiful Mercedes ML63 AMGcame in for a brake check after its owner had noticed the brake warning light had come on, after a quick strip down and report the customer gave us the go ahead to replace its MASSIVE front brake discs and pads and rear pads.

The front brake discs on this three tonne 500+ horse power beast are 395mm in diameter! to put that into context a ford focus has 270mm discs! The AMG also runs Brembo six pot callipers on the front for optimum braking.

 

The owner of this Scirocco R came to have his own lowering spings fitted as he wanted the car to sit lower.

There are Pro”s and Con’s to fitting lowering springs to a road car the Pro’s are –

  • Better handling  (centre of gravity is lower and springs are generally slightly stiffer than OE)
  • Better looking (not everyone thinks so, but if your a petrol head they do)

The Con’s

  • Very hard drive (UK’s roads are not the best so you feel every bump and pot hole)
  • Can cause stress to other car parts (if it feels hard to you imagine how the car feels)
  • Speed bumps (self explanatory)

This BMW 325 Compact Track car came in for a quick Geometry check and adjust before its owners took it to Bedford Autodrome for their Track Day, the owners had fitted all the suspension components them selves and just wanted the alignment checking to make sure it didn’t kill tyres and they could get the optimum performance from their new kit.
