Face pattern options

G88

The signature multi-groove G88 design generates a turbine effect that helps evacuate heat and gases for cooler running. Crafted from OE-spec castings, heat treated for stability, then hand finished. Many applications carry TÜV and ABE approvals.

F2000

Curved grooves that deglaze pads and control surface temperature. A favourite for fast road cars that also see proper track time. Built from TÜV-approved castings, heat treated and hand finished. Pairs brilliantly with Tarox Corsa pads for circuit use.

Sport Japan

Fully drilled and countersunk for efficient gas evacuation, combined with six grooves to keep pads fresh. Manufactured from TÜV-approved castings, heat treated and hand finished. Many applications TÜV approved.

Built to exacting standards

• OE-specification castings with TÜV-approved materials
• Heat treated after each machining stage for strength and dimensional stability
• Precision CNC machining for perfect geometry and run-out
• Individually ground braking faces to an ultra-tight tolerance approaching 0.015 mm for smooth, progressive modulation
• Hand polished for the distinctive Tarox high-shine finish

We run Tarox rotors on our own cars and our customers repeatedly report better bite, reduced fade and excellent longevity. For the best results, team them with matching Tarox pads which are formulated to work in harmony with Tarox heat-treated discs.
