So far no one knows for sure but what we can tell is that the calipers appear to be the same from the F30 Performance Brakes. Those brakes are 370x30 in the front which is larger in diameter but thinner than the e9x fronts and 345x24 rearward, which are both smaller in diameter and thickness. They are also slotted and drilled. The F8X has been seen with only drilled disks so I would assume same caliper (could be different bore sizes or few other factors) with different rotors. Expect larger than what we have now. Would have been cool to get the front brakes from the M5/6. Large and sexy.
