Precision Engineering for BMW F8X Performance

Take your BMW M2, M3, or M4 (F8X platform) to the next level with GiroDisc 400mm slotted rear rotors. Designed for enthusiasts who demand the best, these rotors are compatible with red, silver, or gold calipers, including those equipped with carbon-ceramic brake (CCM) setups. These rotors offer a significant upgrade over stock components, providing enhanced thermal management and consistent pedal feel during spirited driving.

Why Choose GiroDisc?

  • Massive 400mm diameter for increased leverage and stopping force.
  • High-carbon iron alloy for maximum durability and thermal stability.
  • Slotted surface pattern to prevent pad fade and maintain consistent contact.
  • Perfect fitment for F8X models with various caliper configurations.
  • Reduced weight compared to many factory alternatives.

These rotors are built to handle the high-speed demands of modern BMW performance. The intricate vane structure pulls air through the center of the rotor, effectively dissipating heat that would otherwise cause brake fade. Whether you are daily driving or hitting the track, the reliability of these rotors is unmatched. Experience the difference in stopping power and control by upgrading your braking system with components from GGCRACING.
