GiroDisc two-piece floating rear rotors for Mercedes A45 (W176) / CLA45 (C117) / GLA45 (X156) / SLK55 (R172). Direct replacement for the OE disc with no modifications needed, working with the OE calipers. A lightweight rotor upgrade, rather than a big brake kit, maintains the factory brake bias and ABS efficiency.
Key Features
- Curved vane design, developed in racing to act as a centrifugal pump that forces cooling air through the disc
- Floating mount: the drive pins take the braking load while keeping axial and radial float between the hat and disc, so the rotor self centres between the pads
- Once the system is fitted, only the cast iron rotor needs replacing when worn

- Construction: Two-piece floating
- Hat material: U.S. sourced 6061-T6 aircraft specification aluminium
