US 335i's come with the M Sport front brakes as standard, well same calipers, not sure what disc size they use.

Here in the UK, the M Sport brake upgrade gives the 4 pot calipers painted blue, with bigger discs all round. I can't remember if the rear calipers are 2 piston or the standard single sided piston but are also painted blue.

It is basically the same caliper kit as M Performance but with non drilled discs. Which to me is a bonus, having drilled discs on anything other than a track car is stupid.
