E46 M3 Rear Porsche Brembo Brackets

CNC Machined Brackets are designed to fit a Porsche 996 Brembo rear caliper to the E46 M3 rear trailing arm.  The rotor used is the E46 M3 328x20mm rear rotor.  You may use the standard rear rotors or two piece rear floating motorsport rotors (they are the same dimensions).

Brackets are made from high strength steel and cad plated for corrosion resistance.  The studs are made from stainless steel.  Calipers are secured to the bracket/stud combo with supplied ARP™ nuts and washers.

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)

*We also offer a custom DOT approved stainless steel brake line for this bracket using the OEM style retaining ring/grommet.  It is recommended that these brake lines be used when installing this bracket/caliper combination to ease installation and safely reach the rear caliper.
