R1 Concepts 830-40076L GeoPerf Drilled Slotted Brake Rotor Left/Driver Side

The R1 Concepts 830-40076L is a GeoPerf series cross-drilled and diamond-slotted brake rotor featuring GEOMET® anti-corrosive coating. Engineered for drivers who want improved braking performance over stock, this single left/driver-side rotor delivers consistent stopping power and heat dissipation for street and performance driving applications.

Key Features:

• Cross-Drilled Design: Drilled holes reduce rotor surface heat buildup and are chamfered to minimize cracking potential
• Diamond Slotted Pattern: Slots continuously clear brake dust, road debris, and gases from the pad contact surface, preventing pad glazing and extending pad life
• GEOMET® Anti-Corrosive Coating: Long-lasting corrosion protection applied to the hub and inner vane structure for improved appearance and durability
• Mill Balanced Construction: Precision balanced to minimize vibration and brake pedal feedback
• Direct-Fit Replacement: Ready to install straight from the box with no modifications required
• Left/Driver-Side Specific: Directional design engineered for the driver-side position

Break-In Note: Upon delivery, the rotor will be fully covered with GEOMET® coating. During the initial bed-in process, the coating on the braking surface (where pads contact the rotor) will wear away naturally, leaving the hub and inner vane structure coated for long-term corrosion resistance.

The R1 Concepts GeoPerf series is manufactured under the DFC (Disc Friction Concepts) product umbrella and is suited for daily street driving and spirited performance use.
