No worries, we can't all be right all the time!
Our "back and forth" was small enough and friendly enough (i.e. forgetable) that I had to dig back through to find it. I stand by what I said then. The calipers do look nearly identical to the M5 calipers and it would make a great deal of cost sense for BMW to use that identical caliper on the M3. I think also, at that time it was THE best guess to say they were probably dual piston. If they chose to use a single piston instead (still sort of a rumor I guess at this point IMO) I sure hope they have some good reason to do so. Maybe it is the caliper from the 335i? I am not all that excited about that car (because I drove it
) so I don't worry about knowing little details like what the brakes look like.
