Did you find a big difference in the ride once you'd changed to 20"s - i was thinking of upgrading to 21"s on mine

Ride difference, Its not as "crashy" on the bumps and it doesnt seem to follow white lines as much, But im guessing itl get even smoother once the run flats that are on the 20,s have been changed to no rft,s...
It all depends how you like the car to feel...
The car needs its geometry doing aswell, but im trying to find someone local to me [ Blackpool area] who knows how to set it up with less rear negative camber but still maintaining the road holding.
If i take it to the main dealers im guessing theyl just set it up to BMW specs, thus ill continue to get front and rear tyre wear, [outer + inner wear]. ::) ::)
Ill dig out the options list and post up once found...[It has a ,,, few....]
