Choose your rotor style

G88

The iconic multi-groove pattern promotes rapid heat and gas evacuation, helping the rotor run cooler and reducing the risk of vibration or distortion under repeated heavy braking. Ideal for drivers who want maximum bite and aggressive response on fast road and occasional circuit work.

F2000

Curved grooves keep pad faces fresh and temperatures controlled while maintaining rotor strength. A superb balance for mixed use cars that see daily driving plus serious weekend runs or track sessions.

Sport Japan

Features fully drilled, countersunk holes paired with six linear grooves. Designed to vent gases that cause fade while keeping pad surfaces conditioned. A great option for those who want bold looks with genuine performance benefits.
