MMR Performance 6-Piston Front Cup Kit 380mm Big Brake Kit - Dark Anthracite - BMW F2x/F3x (M135i M140i M235i M240i) Forged Monoblock Calipers, 2-Piece Floating Discs

Six‑pot front brake upgrade in Dark Anthracite for BMW F2x F3x

Take your BMW’s stopping power to the next level with this premium six‑pot front brake package. Engineered for the F2x F3x chassis used by the M135i, M140i, M235i and M240i, this track‑capable front axle kit delivers exceptional bite, superb modulation and rock‑steady performance on fast road and circuit days.

Built for serious braking performance

At the heart of the kit are forged T‑6061 aluminium monobloc calipers for outstanding rigidity and pedal feel. They work with fully floating twin‑piece 380 mm rotors that use directional curved vanes to move air efficiently through the disc, controlling heat and combating fade. MMR’s signature grooved faces continually refresh the pad surface for consistent bite lap after lap and mile after mile.

Why enthusiasts choose this setup
