Mine Changed 3-4 MPH when I went from stockies on my MKIV to 17x8 rimsyou dont need suspension, but wheels look like trash with a stock suspension. I wouldnt go larger than 17's on a mkIII because they look like trash. Dont worry about the speedo, it wont be thrown off enough to make a difference. You also have to worry about offsets with new wheels. Too low of an offset might rub on the springs, so you will have to get spacers.
thats why i'm limiting to 15 or 16x7. i dont wanna screw anything up. plus for my needs 7 wide is really all i want. main reason for gettin new wheels is that right now im running on 14s. i mean my nephew has hot wheels cars with bigger wheels. also, how do i know the offset size?you dont need suspension, but wheels look like trash with a stock suspension.

im in nyc 3-4mph is the difference between riding clean and gettin caught with a ticket. nyc cops are very overzealous with tickets if you arent like a supermodel. and im a guy so it really doesnt work that whole flirting thing...Mine Changed 3-4 MPH when I went from stockies on my MKIV to 17x8 rims
