Choose your face pattern

G88 - maximum cooling and bite

The iconic G88 features multiple deep radial slots that generate a turbine effect to draw away heat and gases from the pad face. Expect fast pad deglazing, improved consistency under repeated heavy stops and excellent resistance to fade. Heat treated, OE-based castings, hand finished.

F2000 - track-capable, road-friendly

Curved slots are strategically positioned to manage temperatures and keep pads in their optimum window while maintaining rotor integrity. A brilliant choice for fast road cars that see occasional circuit work. Heat treated, OE-based castings, hand finished.

Sport Japan - cross-drilled and slotted

Through-drilled holes are countersunk to vent gases effectively, while six wide slots refresh the pad surface. The result is confident response and stable performance. Based on OE-spec castings, heat treated and hand finished. Many applications are TUV approved.
