MIA's Description

These replacement rotor rings are designed for existing Brembo or StopTech big brake kits, specifically those utilizing 328x28mm rotors. They are a direct bolt-on two-piece design, featuring a 6061-T6 aluminum "hat" and cast iron discs. The rotors incorporate 48 curved vanes for enhanced cooling, reduce unsprung weight by 4-8 pounds, and offer superior heat dissipation, leading to improved braking performance and reduced stress fractures. They include new floating pin hardware.
