Choose your Tarox disc style
G88 Grooved - The iconic Tarox G88 features multiple radial grooves that create a turbine effect to dissipate heat. Helps the discs run cooler and reduces the chance of warping, vibration or cracking. Based on OE spec, TÜV approved castings, heat treated and hand finished. Many applications are TÜV and ABE approved by the German KBA.
F2000 Curved Groove - Ideal for fast road and regular track use. Curved grooves deglaze pads and manage heat effectively. Fewer grooves than G88 for an optimum balance of heat dissipation and structural strength. Based on OE spec, TÜV approved castings, heat treated and hand finished. Pair perfectly with Tarox Corsa pads for track days.
Sport Japan Drilled and Grooved - Developed for drivers who want aggressive looks with proven performance. One of the few aftermarket discs with fully drilled countersunk holes for effective gas venting to combat brake fade, plus six grooves to prevent pad glazing. Based on OE spec, heat treated and hand finished. Many applications are TÜV approved.
Performance you can feel
- Improved initial bite and pedal modulation
- Enhanced high temperature stability and fade resistance
