Thanks for your comments.
The wheels are in fact off an E90.
225/45/17 runflats fronts and 255/40/17 rears. The second pic has been photochopped, but the car has been lowered anyway.30mm front and 20mm rear.
This is the best bm i`ve had for all round driveability imo.
I am thinking of changing the wheels in the near future to one of these two...
what do you think?
