Engineered to stop hard, lap after lap
Each caliper is precision machined from an ultra‑strong forged billet using extensive 5‑axis CNC work for a beautifully finished, thin‑profile body that clears popular wheel setups while maintaining extreme rigidity. The high cast carbon, fully floating discs offer a far higher friction coefficient than typical steel rotors, improving stopping distances and consistency while allowing thermal expansion between bell and rotor to help prevent cracking.
