MMX Performance - 2-PIECE BRAKE DISCS/ROTORS - REAR BMW F8x 370mm

The 370mm x 24mm 2-piece floating rear discs are the perfect addition to match our MMX front replacement discs. Matching grooves, matching performance.

Our 370mm discs/rotors run up to 30% cooler than OE, and increase cooling efficiency by up to 30%.

Utilising a two-piece 370mm floating design allows our disc and hat to expand radially and axially as they absorb heat generated from 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. The discs also utilise 36 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.

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 vehicle.

As the MMX discs dissipate heat much more efficiently, the factory pad compound works much better in real-world conditions; only when you’re using the vehicle on the track would we recommend considering a different pad altogether. But rest assured, you can use OEM or after-market performance pads with our discs.

Left and right handed 370mm x 24mm discs sold in a pair. Matching 2-piece front discs available.
