BMW E46 M3


Why fit?

The exquisite MMR Performance Big Brake Kit for BMW M3 E46 uses our own forged monoblock 6-piston calipers, paired with 370mm fully-floating two-piece discs. Precision machined to deliver breathtaking stopping performance whether in extreme fast road, or race conditions.

Benefits of fitting?

The MMR Performance 6-piston 370mm front brake upgrade for the E46 BMW M3 is simply a level above anything else on the market for the E46 platform. Designed without compromise for ultimate stopping performance, it's packed with motorsport-inspired features, bringing a true supercar look and feel in the braking department.

At the heart of our brake kit is the lightweight Forged Monoblock Calipers. Rather than two halves bolted together, they're a one-piece construction that starts life as an ultra-strong forged billet. From this billet, extensive 5-axis CNC machining operations give each caliper its stunning finish. It's a construction technique usually reserved only for the highest-specification motorsport brake setups and ensures the ultimate stopping performance when used in extreme road, or race conditions.

The result is a 6-piston caliper that is both stiffer and lighter than any other, combined with exceptional cooling characteristics and stunning detailing. The thin-profile calipers give extreme stiffness and light weight, and aid in wheel clearance packaging. Finally, we offer a colour choice of either a Graphite Grey or Bright Red finish.

The calipers are mated with a set of our high-performance fully-floating high cast carbon two-piece 370mm x 32mm disc assemblies giving a far higher friction coefficient compared to normal steel rotors. They requires a minimum of 18" wheel to clear.

The discs themselves feature a directional curved vein to aid cooling, so reducing the effect of fade. Fully floating mounting between disc and bell allow for thermal expansion and contraction to avoid cracking. The anti-rattle mounts keep it quiet.
