BMW XM (G09) Carbon Ceramic Brakes Upgrade

Build Configuration

This BMW XM G09 upgrades to Brembo BM8 front and BM4 rear calipers with STOPFLEX carbon ceramic rotors. The 8-piston front assembly is paired with a 4+1-piston rear arrangement, documented with the four-disc component package.

  • Front: Brembo BM8 8-piston monobloc calipers with STOPFLEX 410mm carbon ceramic rotors.
  • Rear: Brembo BM4 4-piston calipers plus separate 1-piston calipers with STOPFLEX 380mm carbon ceramic rotors.
  • Pads: STOPFLEX carbon ceramic-compatible brake pads.

The BM8 monobloc 8-piston front calipers and BM4 4-piston rear calipers form this XM’s upgraded service-brake package with our 410/380mm carbon ceramic rotors. The additional 1-piston rear calipers remain part of the complete rear arrangement. CCB-compatible pads complete the friction pairing, while our ceramic rotor material is selected for high-temperature stability.

Our XM carbon ceramic rotor range offers a rust-free friction face and ceramic-glaze finish. Compared with like-sized iron discs, carbon ceramic construction can reduce rotating and unsprung mass across the axles. Low rotor wear and low visible dust are priorities of our CCB pad pairing. Our professional team handles the complete XM brake proposal, bringing the BM8 front hardware, BM4 rear assembly and ceramic friction materials into one upgrade solution.
