The finest big brake kit available on the market, designed specifically for BMW performance enthusiasts and racers.

Performance Friction’s Z-Rated brake kit is designed specifically for your M3 or MZ4! Without question, this brake kit is the best on the market, and that conclusion comes from years of racing domination, not the marketing desk. Unlike other brands whose street kits have only the name in common with their top level racing components, these are the real deal PFC parts that win championships across the board in top-level professional series like Tudor, GRAND-AM, World Challenge, WTCC, Australian V8 Supercars, and the list goes on…

The E46 M3 and MZ4 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.

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 done 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 (not a flimsy bridge push-pin).

Calipers are anodized black.

Notes on Piston Envy: Performance Friction takes their top level racing technology and applies it to everything they design, so every component that comes from their South Carolina manufacturing facility performs at the highest level possible. A properly-designed 4-piston PFC caliper is lighter and has better release characteristics than a similar 6-piston piece. PFC calipers are all made with a maximum of four pistons with the exception of a NASCAR-mandated 6-piston design - which is outperformed by its 4-piston counterpart. If you’re trying to impress piston counters, there are much cheaper ways to do it. If you want the best performing brakes you can buy, look no further.

Rotors
The Performance Friction rotors used in all kits are the newest V3 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. These are the only rotors that are mechanically, thermally and dynamically balanced, which means you will never warp them because they remain balanced in all situations and at all temperatures. New V3 hardware reduces weight an additional half pound from the already light previous V1 and V2 components. Rotors are 355x32mm.

Kit also includes PFC Z-Rated high-performance brake 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.
