Help pls. I need a suspension expert in Berkshire.

[wag]

Hi, I'm running a replica with Spax adjustable shocks on Jaguar springs and the car is dragging its bum and very bad on bumps etc. I'm sure it should be better but I need someone who knows about these things to drive the car and look at the setup for me. I've looked at the net and the Spax site but can't find anyone local. So any suspension contacts you know in the Berkshire area would be most welcome. Thanks.
