These rear brackets will fit both E36 and E46 non-M cars. They are to be paired with either E46 M3 rear rotors or E38 750i rear rotors. The E38 750i rear rotors are the same 328x20mm size and offset as the E46 M3 rear rotor, but have a smaller parking brake to help retain that function.
**The E46 330 uses a larger parking brake like the E46 M3, so use E46 M3 rear rotors on the 330i and 330Ci.
Calipers used for this conversion are Rear Calipers from the 1999-2004 Porsche 996 (non-turbo), the Boxster S or the Cayman S. All these calipers are made from the same Brembo casting.
The Porsche caliper part numbers for this conversion are:
996.352.421 (driver side)
996.352.422 (passenger side)
The pair of rear brackets come with 4 bolts and washers to secure the calipers.
We highly recommend purchasing our conversion specific E36 or E46 rear brake lines depending on which model vehicle you own.
Note1: There is no machining required for the rear calipers to fit with this bracket.
Note2: Does not fit 318ti/Z3 non-M cars. They have a completely different rotor/caliper setup.
