R1 Concepts 830-21048R Drilled Slotted Performance Brake Rotor - Rear

The R1 Concepts 830-21048R is a high-performance rear brake rotor featuring an advanced drilled and slotted design from their GeoPerf series. This rotor combines precision-drilled holes with curved slots to maximize heat dissipation, reduce brake fade, and eliminate harmful gases and debris from the braking surface.

Key Features:

• Drilled and slotted design for superior cooling and consistent bite
• GeoPerf series construction with enhanced metallurgy for durability
• Cross-drilled holes prevent gas buildup and reduce brake fade
• Curved slots continuously clean brake pad surface and expel water
• Direct fit replacement for OEM rotors
• Improved stopping power for performance and towing applications
• Mill-balanced to minimize vibration and noise

R1 Concepts GeoPerf rotors are engineered to deliver race-inspired performance for street and light track use. The drilled and slotted pattern provides aggressive initial bite while maintaining smooth, fade-free stopping power under demanding conditions. Each rotor is precision-machined and mill-balanced to ensure proper fitment and vibration-free operation.
