Purchased some 245 35 17's not got round to putting them on yet.
Just have to see how I go with them. I know there are some 6mm shims on the rears so that will give me a bit more if I remove them. Car is just awful traction wise on the rear at the moment with the 215's. To be honest as soon as it boosts even in 3rd gear it just looses traction which makes it difficult to relax in it to be perfectly honest.
