R1 Concepts 633-13005L RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 633-13005L is a performance drilled and slotted brake rotor from R1 Concepts' RNC (Road & Competition) Series. Engineered for drivers who demand improved stopping power and fade resistance over stock rotors, this rotor combines cross-drilled holes and precision-cut slots to deliver consistent, high-performance braking in both street and spirited driving conditions.

The cross-drilled holes allow heat, gases, and water to escape quickly from the rotor surface, reducing brake fade during repeated hard stops. The slots continuously clean and deglaze the brake pad surface, maintaining maximum friction contact and bite throughout the life of the rotor. The rotor is manufactured from high-carbon G3000 gray iron for excellent thermal stability and noise reduction.

Key Features:

• Drilled & Slotted Design – Improves heat dissipation and reduces brake fade under demanding conditions
• G3000 High-Carbon Gray Iron – OE-grade material for quiet, smooth, and durable operation
• Zinc Dichromate Coating – Corrosion-resistant finish on non-friction surfaces to resist rust and improve appearance
• Precision Balanced – Computer-balanced for vibration-free performance and reduced noise
• Direct OE Replacement – Designed as a direct bolt-on replacement for straightforward installation
• Left Side (Driver Side) – This listing is for the left/driver-side rotor

The R1 Concepts 633-13005L RNC Series rotor is an excellent upgrade for drivers seeking enhanced braking performance without sacrificing daily drivability. Whether used for commuting, canyon driving, or light track days, this drilled and slotted rotor delivers the stopping confidence you need.
