Performance Friction (PFC) brake kits for E46 M3

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.

Calipers

The 4-piston Z31 caliper used in the front on this E46 kit is a Monobloc design, machined from a single piece of allow billet for maximum strength from an FEA-created design that 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. The Z29 caliper in the rear are a 2-piece design, but unlike every other 2-piece caliper on the market that is cast and machined, the PFC Z29 caliper is a full billet piece, 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. Calipers are finished with a black anodized surface.

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 - meaning you will never warp them because they are balanced in all situations, all temperatures. New V2 hardware reduces weight an additional half pound from the already light V1 components. Front rotors are either 323x32mm or 355x32, rear are 321x20mm - properly sized to maximize performance and reduce weight commonly added with overkill kits.

Kit also includes Z-Rated PFC performance pads and the required stainless brake line set.

This kit is vastly superior to de-contented kits for street and race applications made by other manufacturers.  If you have specific questions or would like a more in-depth explanation of features, please call or email one of our experienced technical sales reps for more information.
