Well, that is a wide open question, but let me try. There is 18x7,18x7.5,18x8, and I think 18x8.5 Hell maybe even 18x9. I have 18x7.5 with a +45 offset (very important when purchasing rims) Now, if you go with a wider rim such as 18x8 or higher I recommend you look into purchasing a rim with a higher offset like +48. Have you seen cars with the rims sticking out from under the fender? Well, that is due to improper offset.
how about for 19's? oh and i heard that from a forum that 19's rubs, is that true? if so then if you were to speed and hit something lot a pot hole, would it not smash against that rubbing part and might later cause damage to your car?
Hi there, i have 19x7.5 with +48 offset. My car also has H&R springs and koni's all around on lowest perch. My guess is it's dropped alittle under 2" all around, i have not yet had it rub yet, no problems. Hope this helps. It's a 1995 ls coupe, Nate
