Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Transform your G8x stopping power with MMX lightweight floating rear brake discs. This high performance rear brake upgrade is a bolt-on swap for the factory setup on BMW M3 and M4 G-series models, delivering cooler running, sharper response and confidence-inspiring consistency for fast road and track-day use.
Engineered with a floating two piece construction and matched left and right handed internal vane design, these vented rear discs move more air through the rotor for rapid heat management and fade resistance. The assembly is lighter than the OE steel disc, helping to trim unsprung and rotational mass for improved turn-in and pedal feel without compromising daily drivability.
We use these on our own builds and our customers love the difference: more stable braking over repeated stops, even pad contact across the face and a reassuringly consistent pedal on spirited drives.
- Rear two piece floating brake discs for BMW G8x platform
- Size: 370 x 24 mm, supplied as a matched left and right pair
- Direct bolt-on replacement for the original rear discs
- Directional internal vanes for superior airflow and temperature control
- Lighter than stock to aid response and reduce heat soak
