Im asking this because I will keep the stock suspension and I will not lower my car.

someone told me that stock suspension can't handle 18x8, so what about 18x7.5?
1. OEM wheels are 17x7 with a 48 offset (not 7.5)
2. There is no performance reason to go to 18's especially if you are keeping the same offset.
3. If you are keeping the stock suspension, it means you are not racing the car. Therefore, there is no reason to go beyond 215's or 225's for the width of the wheel. Both of these will fit on 7", 7.5", and 8" rims.
4. 17's will give you a slightly better ride and protect the rim more as there is more sidewall. 18's can give slightly better cornering, but the increase is so slight I doubt if you would notice it.
5. If you have that money burning a hole in your pocket, buy better tires. That is the one thing that will make a big difference if you have OEM tires.

I started a whole thread on this topic and have ended up keeping the 17" OEM rims but changing the tires to 225/45/R17 Michelin Pilot Sport 4S -- the same model that is on the tS (except the tS has 18" rims). I really wanted to justify buying new rims, but in the end, it would have been only for looks. If you are just in it for looks, buy what you want and forget that it might negatively impact performance.
