R1 Concepts 830-48046R Drilled Slotted Performance Brake Rotor - Rear

The R1 Concepts 830-48046R is a high-performance brake rotor featuring both drilled and slotted surfaces for superior stopping power and heat dissipation. Part of the GeoPerformance series, this rear brake rotor combines precision machining with advanced metallurgy to deliver reliable braking performance in demanding conditions.

Key Features:

• Drilled and slotted design for maximum heat dissipation and reduced brake fade
• Cross-drilled holes prevent gas buildup between pad and rotor surface
• Precision slots continuously refresh brake pad contact surface and evacuate debris
• High-quality cast iron construction with enhanced carbon content for durability
• Mill-balanced to minimize vibration and ensure smooth operation
• Black e-coating on non-friction surfaces provides corrosion resistance
• Direct replacement rear rotor for easy installation

R1 Concepts rotors are engineered to exceed OEM specifications while providing the performance benefits demanded by enthusiast drivers. The combination of drilling and slotting delivers improved wet weather performance, reduced stopping distances, and consistent pedal feel under hard braking conditions.
