R1 Concepts 633-39006L Drilled and Slotted Brake Rotor - Left Side

The R1 Concepts 633-39006L is a high-performance drilled and slotted brake rotor designed to deliver superior stopping power and heat dissipation. This left-side rotor features R1 Concepts' signature cross-drilled and diamond-slotted design, engineered to enhance braking performance while reducing brake fade under demanding driving conditions.

Key Features:

• Cross-drilled holes reduce heat buildup and improve ventilation for consistent braking performance
• Diamond slot technology removes brake dust and road debris while preventing pad glazing
• Constructed from G3000 grade cast iron for exceptional strength and durability
• Precision-countersunk drill holes prevent cracking and ensure structural integrity
• Built to OEM specifications for direct fitment with no modifications required
• Black zinc finish provides superior rust and corrosion protection
• Diamond-tipped slot ends serve as wear indicators for rotor replacement timing

Ideal for daily driving, light performance applications, towing, and hauling, this R1 Concepts rotor delivers smoother, quieter stops with extended service life. The drilled and slotted design maximizes brake pad bite while dissipating heat up to 105°F more effectively than standard rotors.
