BMW E36 M3 Front BBK Adapter Brackets

Availability: In Stock

CNC Machined Brackets are designed to fit a Porsche 996 Brembo front caliper to the E36 M3 front spindle.  Two rotors options are available for this brake kit.  The first option is the standard E46 M3 325x28mm front rotor.  The standard E46 M3 rotor with fit with 17 inch wheels.  Utilizing standard E46 M3 rotors requires 12mm to be machined from the mounting boss of the caliper.  We offer this service for an additional charge.
The other rotor option is for 18 inch wheels only, but requires no modification to the calipers.  The E46 M3 CSL 345mm floating rotor is a bolt on setup for this bracket an a 996 caliper.

Brackets are made from 7075-T6 Aluminum and MIL spec black anodized for corrosion resistance.  The studs are made from 17-4 PH pre-hardened stainless steel.  Calipers are secured to the bracket/stud combo with supplied ARP nuts and mil-spec washers.

Calipers used for this conversion are Front 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:
996.351.425 (driver side)
996.351.426 (passenger side)

Calipers will vary in color between Porsche model and options, but the castings will be the same as will the piston sizes. If you are having trouble finding calipers, please contact us.  We may just have a pair of calipers available to sell.
*For off-road use only.
