well ima gonna buy some rims.....they are 18x7.5 wat size tire will i need so i dont have to do any mods to the wheel wells??? thanks

 

i currently have 18x7.5s on my lude they have a 215-35-18r tire no rubbing. but i just bought some 16's the 18's are too heavy if you plan on racing the car i would get some smaller ones. plus the ride quality is absolutely horrible on that small of a tire

 

215/35 are the cheapest, that's what I have, I like them just fine. Then there's 215/40, 225/40, or you can spend a little more if you want the width without the sidewall and get 225/35.

There are no modifications to your car depending on how much it is lowered. My car is lowered 1.75" which forced me to get 215/35/18 or else it might rub.

 

But if I remember correctly the 5th gen has a slightly larger wheel well, which allows for a larger rim. I have seen 18s on a 4th gen but they are just too big IMO. And I believe the OP has a 5th gen correct?
