PSS-10 Coilovers and Ride Height

[Richard Hamilton]

I'm seriously considering fittin a PSS-10 kit to try to reduce the harshness of the ride. The car has just turned 70,000 miles, so I doubt the shocks are in the best of health anyway.

Thing is, I don't want to lower the ride height. We have a lot of speed bumps in my area, and the front splitter catches all too often anyway. The advertisements I have seen all show "30-50mm lowering" but does anyone know if I can maintain the standard ride height?

To my knowledge even if you adjust them as high as they will go you will still be a little lower - perhaps 10-15 mm lower.

Yep, definatley about 10-15mm lower than stock. During corner balancing, I adjusted the rears nearly all the way up, and the fronts lower to give the car a very agressive forward rake look. With the rears any lower than that, I found it a bit too close for comfort over most speeds bumps. :-)

Just to draw a line under this thread, I contacted Bilstein, and they confirmed what has been said by Loren and logray. If you adjust the platforms to give standard ride height, the springs would coil-bind on compression. Also, damper stroke would be reduced, and be less effective.

I have also spoken to a Porsche suspension guru here in the UK (Chris Franklin - Center Gravity) and he assures me he can achieve what I am looking for by fitting new Bilstein B6 dampers. He also told me about the way Turbo rear springs tend to sag after a while, and has a solution to bring the ride height at the back up to standard. Car is booked for 17th September (a measure of his popularity!) so I am hopehul he can sort it out for me.
