R1 Concepts 633-21009R Performance Drilled Slotted Brake Rotor

The R1 Concepts 633-21009R is a high-performance drilled and slotted brake rotor engineered to deliver superior stopping power, heat dissipation, and extended service life. This rotor features R1 Concepts' signature cross-drilled and diamond slotted design, combining the benefits of both technologies for maximum braking performance.

Key Features:

• Cross-drilled design reduces rotor operating temperatures by up to 105°F, preventing brake fade during aggressive driving
• Diamond Slot Technology removes brake dust and road debris while preventing pad glazing to extend pad and rotor life
• Manufactured from high-quality G3000 grade cast iron for exceptional strength, stability, and durability
• Zinc plating provides superior corrosion protection for improved appearance and longevity
• Mill-balanced for smooth, vibration-free stopping performance
• Diamond-tipped slot ends serve as a wear indicator for rotor replacement
• Precision countersunk drill holes prevent cracking and promote smoother bed-in
• Direct OEM fitment with no modifications required

Ideal for daily driving, light track use, towing, hauling, off-road, and street performance applications. The drilled and slotted pattern ensures consistent braking performance while maintaining cooler operating temperatures compared to standard blank rotors.
