A perfect pairing to our 380mm front brake kit! This adapter kit makes it possible to fit the huge yet lightweight 2-Piece M2/M3/M4 370x22mm rotors and the 2-Piston Brembo calipers from the F-Series M2/M3/M4 or M-Sport to any 2, 3, or 4-Series.
These rear brakes are massive compared to stock! The increased rotor size gives this brake package much more thermal capacity. This helps your brakes stop better, for longer. The M rotors also have a huge selection of both aftermarket rotors and pads for the track.
Fitment Notes:
Rear Calipers: 34216799461 and 34216799462 & other color versions available
Rear Rotors: 34212284811 and 34212284812
3-Series/4-Series: Need to slightly trim the brake shield/ebrake
2-Series: Either just bolts on and you lose use of the emergency brake, or swap to a 3 or 4 series knuckle
