Does having 17 or 18in make a different in performance? as far as speed. I thought i read an post in the forum that with 18 you can't get much speed out of it because it'll hit the inside of the wheel or something like that.
of course everyone will bring up the weight issue with larger rims, and this is a valid point, however a more meaningful explanation follows:
- putting on larger tires means that you are effectively raising your gear ratio (numerically lowering), making your car accelerate slower but increasing top speed... The opposite is true upon going from 18's to 16's for example.
