I was pretty impressed with shivaswrath's review and if for any reason my ride is not to my expectations its on BMW.
I'm not an expert either, but looks like you would rub if you dropped your car as is. But serious, I'm not a good person to trust on this. From what I've read, most guys are on 35 front's and 30 rears for the M5 reps I'm buying. And you may consider 255's for the rears instead of 265's.
A lot of guys that have 19"x9.5" M5 reps in back have a 38 offset. Since I'm getting the same tires as you with the 19" wheels, I was curious about your wheel gap.
