Thanks for the suggestions, will look into that. My car is over 11,000 miles now, last 1,000 by me since october.

Am I right to remember that I read somewhere that if you have too much rear wheel grip it can generate understeer (push)? I am sure I read a thread that referred to choosing a rear tyre that was not as great as grip could be to enable a balance front to rear on fast cornering? Or is that waffle?
