Alpha Racing 320mm Front Brake Disc for BMW HP4 (with Magnesium, Aluminium or HP Wheels) (K10) 2012-2014 Ref: AR-HP4 Upgraded high-carbon steel 5.5mm or 6.0mm thick road legal race discs
Thanks to the unique Alpha Racing T-Floater technology, the torque and heat load generated from the rotor’s Steel friction surface passing to the inner Aluminium carrier is transmitted over a significantly larger floater surface area, which results in both better rotor cooling and reduced wear for a longer service life, compared against a floating disc with bobbins.
- High-carbon steel fully-floating rotor
- Black anodised alminium disc carrier
- Centre hole 64mm
- Bolt holes PCD 80mm
- Choice of 5.5mm or 6.0mm* thickness
- T-floated for even better braking performance under all conditions
- Left and right handed drilled hole pattern for optimal heat dissipation and excellent wet braking behaviour
- Compatible with OEM or aftermarket calipers
Approx. Disc weight: 1.590 kg
*Please note: As with all bikes, upgraded discs thicker than 5.5mm may require wheel, spacer, or fork adjustments/modifications to centralise rotors accurately in the calipers and to avoid binding when new brake pads are installed. Please ask if you have any questions about the need for this.
