Girodisc Front 2-Piece Floating Rotors – BMW E90, E92 & E93 M3

Unlock exceptional braking performance with the Girodisc Front 2-Piece Floating Rotors for the BMW E90, E92 and E93 M3. Designed as a direct replacement for the factory front brake discs, these premium performance rotors offer significant improvements in cooling efficiency, reduced unsprung weight, and greater durability without altering the factory braking system.

Unlike many aftermarket big brake kits, Girodisc's lightweight two-piece rotor assembly retains the OEM brake bias and ABS calibration, ensuring predictable braking performance while delivering the benefits of a motorsport-inspired braking solution. Installation is completely bolt-on with no modifications required, making these rotors the ideal upgrade for road, fast-road and track-driven BMW M3s.

Premium Motorsport Engineering

Each Girodisc rotor features a precision CNC-machined 6061-T6 aircraft-grade aluminium centre hat, manufactured from U.S.-sourced material, paired with Girodisc's proprietary high-carbon cast iron rotor ring. The friction rings are poured and machined entirely in-house to maintain exceptional quality, strength and thermal stability under repeated high-temperature braking.

The rotor incorporates curved directional cooling vanes, developed through motorsport competition to function as a centrifugal air pump. This design continuously draws cool air through the rotor, significantly improving heat dissipation and reducing brake fade during aggressive driving or track sessions.

True Floating Rotor Design

The Girodisc floating system uses 10 high-strength alloy steel drive pins with a corrosion-resistant cadmium coating to securely connect the rotor ring to the aluminium hat while allowing controlled radial and axial movement.

This floating arrangement offers several key advantages:

• Allows the rotor to expand naturally under extreme temperatures
• Reduces the risk of rotor distortion and cracking
• Maintains a more consistent brake pedal feel
• Helps the rotor self-centre between the brake pads
• Improves braking consistency during repeated heavy braking

To eliminate the unwanted rattle often associated with floating rotors, Girodisc incorporates specially designed anti-noise spring washers that maintain quiet operation during normal street driving while still allowing thermal expansion under load.

Lower Long-Term Running Costs

One of the biggest advantages of the Girodisc system is its serviceability. Once the friction rings reach their wear limit, you simply replace the cast iron rotor rings while reusing the original aluminium hats. This significantly reduces replacement costs compared to purchasing complete rotor assemblies every time.
