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.

My rears are 2-pot in the 335i.
Yes, the M perf upgrade didn't seem to make sense to me, because all it offered were larger rotors...which, for a non track, commuter car, doesn't make any sense...but it's nice to see that the 4-potter in the US 335i is similar to the one used in the kit!
