I hear ya.
I replaced all the discs and pads on my MPS with drilled and slotted Brembo discs and Yellowstuff pads ...was the first mod I did to the car a couple of years ago. Good brakes are really important to me and the only reason I didn't order the 2NH upgrade for my 330D was because they looked
identical except for painted calipers with an M badge
I've just checked on RealOEM.com and found out that the 330D comes with 330x24 and 300x24 as opposed to 370x30 and 345x24 with the M Sport brakes so that's the same brakes as the 335i?
