Pick your performance pattern

G88 multi-slot

The iconic G88 uses numerous radial slots to move hot gases and dust away from the surface quickly, helping the system run cooler and keeping the pad deglazed. Perfect when you want maximum cooling and crisp initial response.

F2000 curved slot

Fewer, arcing grooves provide a great balance between durability and temperature control. A superb choice for fast-road driving and occasional track work with a refined sound profile.

Sport Japan cross drilled and slotted

Countersunk holes combined with six slots for aggressive pad refresh and efficient gas evacuation. Ideal if you love the look of cross drilled with proven TAROX strength.

Engineering details that matter

• Each casting is heat treated after machining to enhance structural integrity and longevity.
• CNC profiled faces for accuracy, with specialist hand grinding for a uniform, polished finish.
• Consistent thickness and surface tolerance around 0.015 mm for a premium, vibration-free feel.
• Best results when paired with TAROX pads. For circuit use, TAROX Corsa pads are a strong match.
