No probs Dean, can you pm me your address? I will be finished with the navy on friday - discharging, so will be able to pop around any time you like. They are good for twisties, but depends on how hard you push them. I have a borrowed set of springs in there at the moment, 8kg front and I think 6 or 8kg rear - they are sort of intermediate. The original springs that were in are a bit softer - ask Hippy what they were like:). But, I want to go harder still, cos I like the go-kart feel.
N/A, they are gold, adjustable height via circlip similar to bilstein, and 30 posn adjustable damper but they dont use standard coilover springs, they need stock size springs.
Edit, the springs that I have with them currently (not the loaners fitted) are Bestex.
