Default Help.. what wheel size 19in or 20in and why? Or why not?

19s or 20s. Im currently sitting on 19 inch stagger wheel setup with stock suspension, im about to upgrade my suspension to the koni yellows w/ the eibach pro kit and i was thinking about going with the 20 inch stagger set up. Is this a good, bad or ugly idea for a 07 550i base model? Harsh ride? Fender issues? Poor handling? Pls comment

If you stick with the outside diameter of the stock tire, you'll be at 25 or 30 profile on a 20" rim. I'm using 40 series on 18" now, and IMO anything lower is less attractive. The larger the rim diameter, the more rotational mass you have, which affects acceleration and braking.

20' will be very hard from the low profile needed to run the 20's. The 7 runs factory staggered 19' that would ride much better you can put 21's under there!
