I've run the "4 square" setup for the last few winters and have been pleased with the results.
I'm researching whether I can use the winter setup for my E60 M5 on the new F10 M5. I use a set of OEM M6 wheels (F 8.5x19 ET12; R 9.5x19 ET17). I ran an analysis on a spread sheet to see how the different wheel widths and offsets from the stock F10 M5 wheels would impact internal and external clearance. Internal clearance improves by 23-28 mm and extarnal clearance drops by 11 - 16 mm. So the wheels sit farther away from the body of the car, with a change in the wheel centerline of 17 - 22 mm. I passed my spread sheet along to my CA and asked if he could check with a tech if there would be any issues or risk of damage to the suspension. He decided to call the US M-brand manager and ask his opinion. The M-brand manager didn't know the answer, so supposedly he sent my spead sheet to the M engineers in Europe to review and oppine. My CA has not heard back yet, but it's nice to know the M-brand team cares enough about their customers to provide this kind of customer service! I'll reply to this post when I get any information back from Munich.
