excellent thanks again!

re tyres not sure..........thinking of 245/40 to keep the rolling radius almost exactly the same, although could go to a 255/40 I guess.......I'm am concious that I need to balance the rolling raduis vs trying to get a 'low profile' tyre look whilst also trying to fill the arches without spending more money (I don't have right now) on a coliover kit.

Open to any other creative suggections as to other options on tyres though - I did see that Singh wnet for 285/30 on a 20x9 rim which I bet looks good!
