We now offer brackets for the Z4M so you can install the popular Porsche Brembo 996/Boxster-S caliper upgrade. CNC Machined Brackets are designed to fit a Porsche 996 Brembo front caliper to the Z4M or E46 M3 front spindle.

There is only one rotor option for this bracket, the E46 M3 CSL 345mm fronts. This requires 5.5mm to be machined from the mounting boss of the caliper. We offer this service on your calipers for $95 plus return shipping.

This kit with 345mm diameter rotor is for 18 inch diameter or larger wheels only. As stated before, the only modification required is to machine 5.5mm of material from the mounting boss of the calipers. Once the caliper is machined, the E46 M3 CSL 345x28mm floating rotor is a bolt on setup for this bracket.

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 aircraft jet nuts and 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. A pair of calipers can regularly be found between $350 and $450. If you are having trouble finding calipers for that price, please contact us. We may just have a pair of calipers to sell within that price range or we can direct you to one of our caliper sources.

Proper pad placement with this bracket gives a full sweep of the rotor surface. No rust rings on your rotor when using this brake setup.

The same DOT approved brake lines we offer for the E36 M3 will work for the E46 M3.

*For off-road use only.
