Thanks for the response. Yeah, I completely rebuilt the suspension a couple of years back with poly bushes and yellow konis all round. The springs are 'ok' but a bit pitted and I wanted to change them at the same time for some new ones but just couldn't get hold of any. The only ones I can find are on eBay and I get the feeling that they are a pretty generic spring rate i.e., fits different models, and so could be softer than I have at the moment. The ride I currently have is good, I do like it, it's much firmer than before but not too stiff (as I said I'm beyond those days of teeth loosening springs). However, I don't want to go any lower, so I really am lookign for standard length springs with maybe a mild uprate in ratem, maybe just 10%.
But I'm not in any major rush and so just wanted to start planning, ask around and see if I can gather the spec data and then approach the spring manufacturer when required.
Cheers again for your help.
