Product Details

The R1 Concepts 623-54187R is an RNC Series drilled disc brake rotor engineered to deliver improved stopping performance and thermal efficiency over a standard OE replacement rotor. Precision-machined from high-quality cast iron, this rotor features a drilled pattern designed to dissipate heat and gases that can build up between the pad and rotor surface during braking.

Key Features:

  • Drilled Pattern: Cross-drilled holes promote rapid heat dissipation and help evacuate gas and moisture from the braking surface for consistent, fade-resistant stopping power
  • Premium Cast Iron Construction: Manufactured from G3000-grade cast iron for strength, durability, and stable braking performance
  • Corrosion-Resistant Finish: Coated with R1 Concepts' proprietary rust-inhibiting finish to protect non-braking surfaces from premature corrosion
  • Direct OE Replacement Fit: Engineered as a direct-fit replacement — no modifications or drilling required for installation
  • Precision Balanced: Computer-balanced during manufacturing to minimize vibration and pedal pulsation
  • OEM-Style Hardware Compatibility: Designed to work with your vehicle's existing caliper and hardware

The R1 Concepts RNC Series is an ideal upgrade for drivers seeking enhanced braking performance and a cleaner appearance over a stock replacement rotor. As with any rotor replacement, brake pads should be replaced at the same time for optimal break-in and performance.

Great price and delivery time on live well timer order. Other order of boat trailer guidepost kept getting cancelled so placed call to boatplicity to find out they do not sell that part. An email to me explaining why order was cancelled would have been nice. Otherwise all good.

fast service

The picture did not match what I purchased. Only part number and description were correct.

We found a tire here that was hard to find and it was shipped quickly. Great experience and would use this company again.

Ordering my tire was a breeze. The website was easy to navigate and I received a delivery within the time frame I requested. I would recommend thmotorsports.com.

Great as long as it gets delivered by Thursday

Good service!

Just fulfilled my expectations!
