Choose your disc style

G88 multiple radial grooves

The iconic G88 features numerous deep radial slots cut on custom machinery to create a turbine-style effect that helps move hot gases away from the braking surface. Expect cooler temps, excellent deglazing of pads and strong resistance to warping, vibration or cracking on spirited drives.

F2000 curved slots

Ideal for mixed use road and circuit work. The distinctive curved grooves continuously refresh the pad face and balance cooling with structural strength. F2000 offers superb pedal consistency and durability for fast road and track day sessions.

Sport Japan drilled and grooved

With fully drilled, countersunk holes plus six sweeping grooves, Sport Japan prioritises gas evacuation and pad cleanliness to fight fade and keep response crisp. Tough looks with genuine performance benefits for everyday and enthusiastic driving.
