This is a pair of OEM 1-pice brake rotors for M Sport 30i models found on some G20 330i, G22 430i, G30 530i, G01 X3 30i, G02 X4 30i, G29 Z4 30i, and Supra A90/GR (4-cylinder B46). M Sport brakes have blue or red Brembo 4-piston calipers instead of the plain grey single-piston brakes. These brakes have option codes 02NH, S2NH, ZTR, or 03M2. These rotors measure 348x36mm.
These are also used on G01 X3 30i, G02 X4 30i with the optional Dynamic Handling Package (option code ZDH or S2NH).
These rotors replace BMW part numbers 34116860911 and 34116860912.
Purchasing OEM rotors guarantees high-quality castings and tolerances to reduce warping and vibration while also ensuring an exact fit. These rotors work well with any street, street/track, or dedicated track/race pads in our catalog. These rotors typically hold up very well to the stresses of track and autocross, however, we recommend floating and/or slotted rotors for customers using their cars on track regularly.
1-piece rotor. This rotor is a single-piece cast iron rotor. The factory BMW rotor is a 2-piece iron disc with an aluminum hub. BMW advertised the lighter weight as a way of lowering emissions and improving fuel economy. There is likely no performance difference between them but these single cast rotors will be slightly heavier compared to stock. We also offer OEM 2-piece rotors if you wish to keep the lighter two-piece design.
