R1 Concepts 830-72040R Performance Brake Rotor - Drilled and Slotted

The R1 Concepts 830-72040R is a high-performance drilled and slotted brake rotor designed to deliver superior stopping power and enhanced heat dissipation. This rotor features precision cross-drilled holes and diamond slot technology to provide maximum braking performance for street, sport, and towing applications.

Key Features:

• Cross-drilled design reduces rotor operating temperature by up to 105°F for improved fade resistance
• Diamond slot technology removes brake dust and road debris while preventing pad glazing
• Countersunk drill holes prevent cracking and ensure smoother brake pad bed-in
• Chamfered edges maintain rotor integrity under high-stress conditions
• Made from G3000 grade cast iron for exceptional strength and durability
• Zinc plating provides superior corrosion protection
• Direct OEM fitment with no modifications required
• Mill-balanced for smooth, vibration-free operation

The diamond-tipped slot ends serve as a built-in wear indicator—when the tips are gone, it's time for rotor replacement. Ideal for drivers seeking a medium performance upgrade over factory brakes, this rotor combines reliable daily driving performance with enhanced stopping power for spirited driving, light track use, or towing applications.
