MMX 380 mm Two-Piece Front Disc Set for BMW F80 F82 F83 F87

Give your BMW M-car the braking confidence it deserves. This premium pair of 380 mm front discs is engineered for owners who want powerful, repeatable stopping performance, cooler running and impressive durability on spirited road drives and circuit days. Expect noticeably stronger bite, better pedal modulation and far more consistent behaviour when hot.

Why these make a difference

The factory 380 mm drilled setup can struggle under sustained heat. MMX solves this with a fully floating two-piece arrangement that allows the cast iron ring to expand and contract independently of the lightweight aluminium centre. That means less risk of distortion, fewer heat-related issues and a more confidence-inspiring pedal every time you brake hard.

• Runs up to 30 percent cooler than the stock discs for reduced fade and more stable friction
• 380 mm diameter x 30 mm thickness for serious thermal capacity without compromising fitment
• Handed internal vanes with 72 curved passages that actively draw cooling air through the rotor
• Left and right specific for optimal airflow and consistent high-speed stopping
• Slotted friction faces to clear gases and debris for sharper initial response
• 6061-T6 aluminium centre hats to cut unsprung mass and improve steering feel
• High-temperature rotor alloy designed to stay true under extreme use
• Compatible with OE pad compounds and popular performance pad choices
• Ideal for fast road, track days and daily use where reliability matters
• Long service life compared with many one-piece alternatives when driven hard
