Rear M Sport Dimpled Brake Rotors (345x24)(Pair) - F22 228, F30 328i/328iX, F32 428i/428iX (M Sport S2NHA)
These REAR rotors fit to F22 228, F30 328, and F32 428 models with the optional M Sport Brakes upgrade (option code S2NHA). These rotors are larger and have a dimpled/slotted surface compared to what came on the base, Luxury, Modern, Sport, and M Sport trim packages. The dead giveaway whether or not you have the M Sport option is the rear caliper - the S2NHA option added 2-piston Brembo calipers on the rear while all of the brakes were a standard single piston caliper (a Brembo caliper was also used on the front for S2NHA).
These rotors were originally part of the M Performance package, which was an accessory installed after the car was delivered. It was BMW's version of an aftermarket big brake kit but these rear rotors happen to be a direct fit to 228/328/428 when equipped with the optional S2NHA M Sport brake upgrade. They are dimpled and slotted to improve brake pad feel and give the brakes a sportier and more aggressive look. In addition, they are larger that the standard brake rotors to help in braking performance, especially when driven hard.
