I am sorry guys, was out of the country / no internet access.
Replied to all the PMs hoping to address all questions.
For the wheel side of things... and benefit of all interested I can say that currently the alloys fit the "standard" tires sizes.. i.e. 235 front and 265 back. I guess you can go one or two notches wider but not much beyond. I will try to get the exact alloy sizes but I had bought them to be used as BMW designed the car to operate...
PM for price considerations but I will prefer group deal with the wheels+brakes.
