Transform your stopping performance with VBT high carbon slotted discs. These precision CNC machined rotors use a curved groove pattern to sweep away dust, gases and water for stronger bite, better pedal feel and more consistent performance under repeated heavy braking. Designed as a direct fit to the original mounting points, they deliver a true bolt-on upgrade without modification.

Built from high carbon cast iron for strength, stability and excellent heat control, this set is ideal for fast-road use and spirited driving. The curved groove layout helps manage temperature and keeps the pad face fresh, reducing fade and promoting even wear for long-lasting, confidence-inspiring braking.
