Are you thinking about lowering your car eventually?
215 on a 9 is not a massive amount believe it or not and its certainly not a silly/dangerous amount.
I think 215/40 will be fine and then 195/45 on the front. Also depends on the brand of tyre too. Toyo stretch nicely as do Nankangs but some do not strech that well.
I wouldn't go for a 225 rear as this is too big and will look a bit silly, unless you get a very low profile tyre.
What would I do without ya! Thanks for all this help matey, was already thinking 195/45 for the front, and ill go 215's on the back then
Yeah I will be lowering in time, just not anytime in the near future
