R1 99-05 Mazda Miata (NB) Rear Left Slotted Black Brake Rotor

Upgrade the braking performance and appearance of your 1999-2005 Mazda Miata (NB) with the R1 Concepts RNC613-54003L rear left slotted black brake rotor. Designed as a direct-fit replacement for the rear driver-side position, this rotor combines functional slotting with a corrosion-resistant black finish for dependable performance and a clean, performance-oriented look.
The slotted surface helps refresh the pad contact area during braking by managing heat, gases, and friction material buildup. This can support consistent pedal feel and reliable stopping performance during daily driving, spirited road use, and other demanding conditions. The black coating also helps protect non-friction surfaces from corrosion while maintaining the rotor’s finished appearance behind the wheel.
Manufactured for compatibility with the NB-generation Mazda Miata, the R1 Concepts RNC613-54003L is intended for straightforward replacement of the original rear left rotor when service or performance upgrades are needed. Confirm vehicle fitment and replace rotors in accordance with the vehicle manufacturer’s service recommendations. For balanced braking performance, inspect the matching rear rotor, brake pads, caliper hardware, and related components during installation. This product is sold as one rear left brake rotor.
