Product Details

The R1 Concepts 623-31015R is a precision-engineered drilled brake rotor from R1 Concepts' RNC (R1 No-Coat) Series. Designed as a direct OEM replacement, this rotor delivers confident stopping performance without requiring an extensive break-in period. The drilled pattern promotes superior heat dissipation and gas venting, reducing brake fade during demanding driving conditions.

Key Features:

  • Drilled Pattern: Precision-drilled holes enhance airflow and cooling, reducing heat buildup and improving overall braking efficiency
  • G3000 Grade Cast Iron Construction: Manufactured from high-quality G3000 grade cast iron for excellent thermal conductivity and long-lasting durability
  • OEM-Matched Specifications: Engineered to meet or exceed original equipment specifications for a direct, no-modification fitment
  • No-Coat (RNC) Finish: Bare cast iron surface ready for immediate installation and bedding without a zinc coating on the braking surface
  • Balanced and Precision-Turned: Each rotor is precision-machined for proper balance, minimizing vibration and pedal pulsation
  • Vented Design: Internal venting channels promote continuous airflow between rotor faces for consistent thermal management

The R1 Concepts RNC Series is an ideal choice for drivers seeking a straightforward, performance-oriented replacement rotor. Paired with quality brake pads, this drilled rotor provides the stopping power and rotor longevity expected from one of the industry's leading brake component manufacturers.

It was great

I have one of these on another boat. I love it and it's saved my lower unit more than once when I unexpectedly found a stump or hard bottom.. It also allows me to run with the motor higher because if the set back.
