R1 Concepts 631-52012L Cross-Drilled Slotted Brake Rotor - Left

The R1 Concepts 631-52012L is a premium cross-drilled and slotted brake rotor designed for enhanced braking performance in daily driving conditions. This left side (driver side) rotor features R1 Concepts' signature diamond slot technology combined with precision cross-drilling to deliver superior stopping power and heat dissipation.

Key Features:

• Cross-drilled and diamond slotted design for maximum stopping power and durability
• Manufactured from G3000 grade cast iron to OEM specifications for reliable performance
• Silver zinc plated coating protects against corrosion for longer rotor life
• Precision drilling reduces heat buildup by up to 105°F for consistent braking
• Diamond slot technology removes brake dust and debris while preventing pad glazing
• Non-directional rotor finish promotes faster, more even brake pad break-in
• Mill-balanced for smooth, vibration-free operation
• Direct fit replacement with no modifications required

The drilled and slotted design extends the life of both the rotor and brake pads by improving ventilation and preventing the buildup of gases and debris. The silver zinc coating on the hub and non-friction surfaces resists corrosion, maintaining the rotor's appearance and performance over thousands of miles. Ideal for passenger vehicles and light trucks requiring upgraded braking performance for daily driving, towing, or light performance applications.
