Purchase Performance Friction (PFC) brake kits for E46 M3 and MZ4

New from Performance Friction - the new line of Z-Rated brake kits specifically for your BMW!  Born from obsessive engineering right here in the USA and delivering years of racing domination. PFC components win Championships in many forms of professional racing series including Champ Car, ALMS, Rolex, World Challenge, Grand-Am Koni, WTCC, Australian V8 Supercars, and others.

The E46 M3 kit was specifically designed to meet the needs of the BMW Performance enthusiast and racer. Brake bias is moved slightly to the rear for improved braking performance in both front-only and 4-wheel applications.

Overview

Calipers

Front: The 4-piston Z31 (with 355mm x32mm disk) calipers used for the E46 M3 are Monobloc designs, machined from a single piece of aluminum alloy billet for maximum strength.  This FEA-created design optimizes weight while keeping the caliper rigid. This unique caliper uses four pads per caliper - one per piston for an incredible bite and the ability to mix pad selection for mixed-use cars.

Rear: The Z29 calipers (with 321mm x 20mm disk)  are a 2-piece design, but hs the unique distinction of starting as a full billet unit, machined from a single piece of alloy. Caliper halves are bolted together with a total of four mil-spec bolts and nuts (not threaded into the other caliper half). These two features make this caliper both incredibly light and incredibly strong to reduce flex.  This design provides greater strength than cast designs and greater precision than seperately-machined designs.

Calipers are finished in your choice of red, silver, or black.

Rotors

The Performance Friction rotors used in all kits are the newest V2 Direct Drive Rotors. Made from a precision casting, all external surfaces are machined to tolerances of 0.004", including the OD of the vein area that most manufacturers leave rough-cast. This is the only rotor that are mechanically, thermally, and dynamically balanced.  Going to these extreme measures ensures the rotor is balanced in real-world situations, accomodating actual heat and assembled stress.   New V2 hardware reduces weight an additional half pound from the already light V1 components. Front rotors are 355mm x 32mm, rear are 321mm x 20mm - properly sized to maximize performance and reduce both static weight and rotating mass.

Complete Kit

All kits include Z-Rated PFC performance pads , all necessary brackets and hardware, and the required stainless brake line set.
