R1 Concepts Drilled Slotted Brake Rotor RNC Series Performance Rotor

The R1 Concepts RNC Series drilled and slotted brake rotor is a performance replacement disc brake rotor. It is built to improve stopping feel and heat management over a standard smooth OEM rotor. It installs as a direct bolt-on replacement, so no modifications are needed.

Key Features:

• Drilled and slotted surface: Cross-drilled holes help vent heat, gas, and water from the rotor face. Slots sweep debris from the pad surface and help prevent glazing.
• Cast iron construction: The rotor is cast from high-carbon grey iron for strength, durability, and thermal capacity.
• Corrosion-resistant coating: A zinc-based coating on the hat and other non-friction surfaces resists rust in storage and in service.
• Precision machined and balanced: Machining to OE-style tolerances is intended to keep vibration and pedal pulsation low for smooth braking.
• Direct OE-style fit: The rotor keeps factory mounting dimensions for straightforward installation.

The RNC Series suits drivers who want better braking performance, less brake fade, and better wet-weather bite. It is a practical upgrade for street and spirited driving without moving to a full big-brake kit. For best results, pair it with quality brake pads and follow the proper pad bedding procedure.
