I'm getting bloody tired of looking at those sadly small (and narrow) 17" OEM wheels on my '08 coupe! Anyone here swapped these out with the 18" wheels found on the V6 model??

Im wondering is there a ride height difference between the I4 and V6 model? More specifically, will the 18's fill the wheel well up just as nicely as on the V6?

Any advice on swapping to 18's is appreciated. Thanks.
