Performance Friction E46 M3/MZ4 Brake Kit

New from Performance Friction - the new line of Z-Rated brake kits specifically for your BMW! Without question, this brake kit is the best on the market and that conclusion comes from years of racing domination, not the marketing desk. Also, unlike other brands whose street kits have only the nametag in common with their top level racing components, these PFC parts are the real deal that win Championships across the board of top-level professional series Champ Car, ALMS, Rolex, Grand-Am Continental, World Challenge, WTCC, Australian V8 Supercars, etc, etc...

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

Performance Friction calipers all start life as a billet aluminum block, machined into a one-piece monobloc caliper.  These are not the sand-cast calipers used by many other manufacturers and are therefore both lighter and stronger than anything on the general market.

• Z31 Front Caliper (4-Piston, 4-pad) - This caliper uses 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. Multi-pad design uses four pads per caliper - one per piston for an incredible bite.
• Z45 Front Caliper (4-Piston, 2-pad) - The Z45 caliper starts life as a PFC Monobloc, but in the final machining stages is cut in half - originally to meet rule requirements for GRAND-AM racing which required a 2-piece caliper.  Caliper maintains incredible stiffness even with an open bridge due to oversized mil-spec fasteners and a structural bridge bar.
• Z29 Rear Caliper (2-Piston, 2-pad) - A full billet piece, machined from a single piece of alloy, unlike every other 2-piece caliper on the market that is cast and machined.  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 anodized and then powdercoated black.  Custom colors available with a 6-8 week lead time.

Piston Envy - Don't see the 6-piston option you wanted?  That is because they don't perform as well as a properly-designed 4-piston caliper which addresses the pad taper issue properly with the ability to stagger bore diameters.  PFC calipers are all made with a maximum of four pistons with the exception of a NASCAR-mandated 6-piston design - that is outperformed by its 4-piston counterpart...

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.  

Size Note - Performance Friction rotors are a premium performance part.  You are purchasing a better brake kit, not just a big brake kit.  Discuss rotor sizing for your application with one of our salesmen - the biggest available is not always the best for your intended use.

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

This kit is vastly superior to most 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 one of our experienced technical sales reps for more information.
