Coupe suspension recomendations ?

[John.]

After a run down the Borders at the weekend I'm thinking I should do something with my suspension, I recon it's on it's original shockers cause they bottomed out on numerous occasions.
Was gonna just get new shockers as the car sits nice and I don't want to ruin the ride, new Bilstein OE shockers will set me back £370......but Spax do a kit(-40mm) for £360 although it says not for 20v.......but then they list a spring kit that fits both 4 and 5 cylinder engines ??
It was here that I was looking.....http://www.motorsportworld.co.uk/

The car is a g-plate coupe 20v quattro.

Has anyone got any recomendations ?

John.
