R1 Concepts 830-27028L Drilled Slotted Performance Brake Rotor - Left Side

The R1 Concepts 830-27028L is a high-performance drilled and slotted brake rotor designed to deliver superior stopping power and thermal management. Part of R1 Concepts' GeoPerf (Geometrically Optimized Performance) Series, this left-side rotor features advanced engineering for enhanced braking performance in demanding driving conditions.

Key Features:

• Cross-drilled holes with countersunk design prevent cracking while reducing rotor temperatures by up to 105°F
• Diamond slot technology removes brake dust and road debris, preventing pad glazing and extending component life
• Constructed from premium G3000 grade cast iron for exceptional strength, stability, and durability
• Zinc-plated finish provides superior corrosion resistance and improved appearance
• Diamond-tipped slot ends serve as a wear indicator for rotor replacement
• Engineered to OEM specifications for direct-fit installation with no modifications required
• Non-directional finish promotes faster, more even brake pad bed-in

Ideal for daily driving, light track use, towing, hauling, and street performance applications. The combined drilled and slotted design maximizes heat dissipation, extends pad and rotor life, and delivers consistent, fade-resistant braking performance. R1 Concepts rotors are manufactured with over 20 years of automotive brake expertise and backed by a manufacturer's warranty for quality assurance.
