Sorry for the Thread revival but as I haven't a clue about wheel fitments, I'd thought I best ask before purchasing.
My mate has some aftermarket wheels that he bought for his E61 estate but never fitted, they are; Front = 20x9 ET20 and the Rear = 20x10.5 ET25.
The rear do have more of a concave than the fronts.
So 2 questions,
1. would they fit?
2. If they fit, what size tyre (Tires) would I need?
The car is currently at standard ride height (m-sport) but I am looking at fitting coilovers in the not to distant future.
