Rotora 8-Piston Front Big Brake Kit (BBK) Model No. RF801 with 405 x 36mm (16”) 2-piece disc brake system (drilled and slotted) with brackets specifically designed for 20” BMW E9X M3 (5 x 120 bolt pattern). The existing pads are 13mm thick which is about 50% of new. This sale includes the required mounting bolts (see pictures).
I have been told by Rotora Technical Support (Loren, 626-813-7900 (ext. 115)), that this system should fit any 20” BMW OEM such as X3, X5, or X6 in addition to the E9X M3. Rotora has informed me that they have spare parts for this model should the new buyer every require them and that they have brackets for the X3, X5, and X6 (no other hardware is required if you are fitting it to an E9X M3 equipped with 20” wheels).
Note that these calipers can be easily repainted to any other color that you may require. I recommend either the G2 brush-on system or the Dupli-ColorPro spray. I will include four extra M Power stickers (black) with the sale.
And according to Rotora, they can take this system as a trade-in on any of their other systems as found on
