As an fwi I recently went from a 235/40/17 front to 225/45/17 for my track setup.Reason is that I wanted to go back to p-zero-c from yoko a032r.The new front works ok with 275/40/17 rear,as far as tcs,but boy is it tall.We had to bite the bullet and remove the plastic fender liner and grind down the nubbin were the body welds form a small point at the back of the well.Removing the lastic does free up some space,looks like you could get a 245 in there,anyone else try this?The only downside is every drive is now like driving a pinball machine or marriachi band.lol
