MMR Performance Nickel Plated 355 mm Six-Pot Front Brake Upgrade for BMW 1 Series F20 F21 and 2 Series F22 F23

Transform your 1 Series and 2 Series braking with this front axle performance package from MMR Performance. The forged monoblock six-piston calipers and 355 mm two-piece floating rotors deliver fierce initial bite, rock-solid pedal feel and repeatable stopping power for fast road and track-day driving. If you want confidence-inspiring deceleration and real heat management, this kit is the answer.

We run this setup ourselves and it has been a standout upgrade. Customers report stronger bite, improved modulation and far better resistance to fade on spirited drives and circuits alike.

Why it works

• Six-piston forged monoblock aluminium calipers for stiffness and control under high temperatures
• 355 mm FC-25 two-piece fully floating rotors for superior thermal stability and reduced unsprung weight
• Directional curved internal vanes that move air efficiently to keep disc temperatures in check
• Grooved faces to de-glaze friction material and maintain consistent bite in wet and dry conditions
• MMR fast-road pad set, AP6 pad shape for easy future pad swaps with wide compound choice
• Braided stainless front brake hoses for a firmer, more consistent pedal
• Billet steel mounting brackets and quality hardware included for a precise install
• Nickel plated caliper finish that looks premium and shrugs off corrosion
