R1 Concepts 830-31049L DFC GeoPerf Drilled & Slotted Brake Rotor

The R1 Concepts 830-31049L DFC GeoPerf Drilled & Slotted Brake Rotor is a high-performance replacement brake rotor engineered for drivers who demand superior stopping power and thermal efficiency. Part of R1 Concepts' GeoPerf lineup, this rotor combines precision drilled holes and machined slots to deliver consistent, fade-resistant braking performance under demanding conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes and surface slots work together to dissipate heat rapidly, evacuate gas and debris from the rotor face, and maintain pad-to-rotor contact for maximum bite
• GeoPerf Technology: Geometrically optimized perforation and slot pattern for balanced strength and cooling performance
• Direct-Fit Replacement: Engineered to OEM specifications for a straightforward, bolt-on installation with no modifications required
• Corrosion-Resistant Finish: Zinc or e-coat finish applied to non-friction surfaces to resist rust and maintain appearance
• Precision Balanced: CNC-machined to tight tolerances to eliminate vibration and pedal pulsation
• High-Carbon Iron Construction: Premium metallurgy for improved thermal capacity and long rotor life

The R1 Concepts 830-31049L is a left-side rotor, designed as a direct OEM replacement that upgrades stopping performance beyond stock. It is an excellent upgrade for street performance, towing, or spirited driving where consistent braking is critical.
