Jamie, Chris Wiggle swears with his Eibach springs on std good condition dampers.
Personally, i find it too soft but its a lot better than totally standard stuff, Im in the same boat at the moment... I did order a set of spax rsx but they were taking the piss with delivery so cancelled them. Ive been put off many times with the gaz stuff and i will be doing light track, B roads and the gaz gold stuff might be a bit of a handful.
Just been out in ryans turbo and hes running H&R's and i found them to be far too soft for me. So, maybe adjustable Koni dampers with Eibach springs would be suited to you. For me im not too sure if the height would be brought down enough
