MMX 2 Piece Brake Discs (Rear) – BMW M4

MMX Performance disc upgrades are designed to directly replace your OEM brake discs and come complete with left and right-handed, two-piece floating discs. Each disc features much larger, more efficient directional cooling vanes to ensure even braking performance, pad wear and cooling capability.The 370mm x 24mm 2-piece floating rear discs are the perfect addition to match our MMX front 380mm replacement discs. Matching grooves, matching performance.

Utilising a two-piece 370mm x 24mm floating design allows our disc and hat to expand radially and axially as they absorb heat generated from hard use, avoiding the most common cause of warping and cracking seen in single-piece discs. Due to the efficiency of this design, MMX discs last considerably longer than factory discs. The friction surface features our trademark groves that increase bite and remove debris from the pad surface giving the perfect balance between brake feel and longevity.The centre hat is crafted from 6061-T6 aircraft specification aluminium. Our grooved discs are constructed from proprietary metal alloys, that can withstand immense braking temperatures while holding form.

Internal vanes are used to draw air through the centre of the disc outward, allowing the heat to transfer as it passes. The rotation of the discs and vanes play an important role in brake cooling as it acts as a pump to move air and unlike the OEM brake discs, our disc upgrade consists of a right and left-hand disc to optimise cooling and ensure consistent stopping power for your M-Car.
