MMX Performance G8X M2 / M3 / M4 2-Piece Floating Rotor Set - Front 380x36mm

Increases cooling efficiency up to 30% compared to OE discs/rotors

Upgrade your BMW G8X's braking power with MMR Performance G8X M2 / M3 / M4 2 Piece 380mm Front Rotors. Designed for superior performance, these discs provide exceptional stopping power and enhanced heat dissipation, making them a top choice for enthusiasts and track professionals alike.

G-Series M-Cars come with a fairly substantial 6-pot brake setup straight from the factory. Whilst the stock caliper works well, the same can’t be said for the discs. The factory 380mm drilled discs certainly look the part but soon show their flaws with some spirted or on-track driving.

Utilizing a two-piece 380mm x 36mm 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, MMR 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.

Our center hat is crafted from 6061-T6 aircraft specification aluminum. Our grooved discs are constructed from proprietary metal alloys, that can withstand immense braking temperatures while holding form. Our discs also utilize 72 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.

Internal vanes are used to draw air through the center 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 optimize cooling and ensure consistent stopping power for your vehicle.

As the MMR 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.
