Choose your face design

G88 - multi groove for maximum cooling

The iconic G88 uses numerous radial slots cut with dedicated machinery to create a turbine effect. Airflow through the disc helps shed heat and evacuate gases, keeping pads in their ideal window and reducing the risk of fade, cracking or vibration. Made from TÜV approved castings, heat treated and hand finished. Many applications carry TÜV and ABE approvals.

F2000 - curved slot all rounder

A favourite for fast road and track day use, F2000 features sweeping curved slots that continuously refresh the pad face and control temperatures. With fewer, deeper grooves than G88, it balances bite, cooling and disc strength for everyday usability with serious performance. Produced from OE-spec TÜV approved castings, heat treated and hand finished. Pair with Tarox Corsa pads for track work.

Sport Japan - cross drilled and grooved

Sport Japan combines fully drilled, countersunk through-holes with six grooves per side. The genuine through-holes release gas and dust more effectively than dimples, while the slots resist glazing and keep friction consistent. Built from TÜV approved castings, heat treated and hand finished. Most applications are TÜV approved.

Built the right way

• Heat treated after machining to relieve internal stresses for long-term durability
• Individually surface-ground to ultra tight tolerances for a flawless, even contact patch
• Engineered to match OEM dimensions for a true plug-and-play upgrade
