Product Description

The Girodisc 380mm 2-Piece Floating Front Brake Discs / Rotors are a direct replacement front brake upgrade for selected BMW M2, M3 and M4 models fitted with blue calipers and factory iron rotors.

Designed to replace the OE front disc with no modifications required, the Girodisc system bolts directly to the vehicle and works with the original calipers. This allows the car to retain factory brake bias and ABS functionality while benefiting from Girodisc’s lightweight 2-piece floating rotor construction.

Each rotor uses a 6061-T6 aircraft specification aluminium centre hat paired with Girodisc’s proprietary cast iron disc. The rotor features a curved vane design developed through racing, helping move cooling air through the disc to manage brake temperatures during demanding road and track use.

The floating mount system uses 10 high-strength alloy steel drive pins, allowing axial and radial float between the hat and disc. Anti-noise spring washers help reduce cold noise while allowing the rotor to expand with heat and self-centre between the pads.

Sold and priced as a front axle pair, these rotors allow the cast iron disc rings to be replaced separately when worn.
