Product Details

The R1 Concepts 623-54139R RNC Series Cross-Drilled Brake Rotor is a high-performance replacement disc rotor engineered to deliver improved stopping power, better heat dissipation, and enhanced durability over standard OEM rotors. The cross-drilled hole pattern reduces rotor weight and allows heat and gases to escape quickly from the braking surface, helping to minimize brake fade during repeated or heavy stops.

Key Features:

  • Cross-Drilled Design: Precision-drilled holes promote rapid heat venting and help clear water, debris, and brake dust from the pad contact surface
  • Corrosion-Resistant Coating: Silver zinc plating on the hat and non-braking surfaces protects against rust and extends rotor appearance and service life
  • OEM-Grade Cast Iron Construction: High-carbon iron formula provides consistent friction characteristics and long rotor life
  • Precision Machined: CNC-machined to tight tolerances for smooth, vibration-free braking and proper fitment
  • Direct OEM Replacement: Bolt-on fitment with no modifications required — designed to match original mounting dimensions
  • Right Side (Passenger Side): The "R" suffix designates this as the right/passenger-side rotor

R1 Concepts RNC Series rotors are ideal for drivers seeking a performance upgrade from stock while maintaining everyday street reliability. Whether used for spirited driving, light performance use, or simply replacing worn OEM rotors with a better alternative, the 623-54139R delivers a noticeable improvement in braking confidence and feel.

Shipping was fast and received tires in a couple of days. Great prices also.

Best price. Delivery was spot on.

This company is super fast to get you your order! I ordered online and figured it would be at least a couple days or so until my order would even get processed. I think they overnighted it to me! The package showed up undamaged and sealed. Unfortunately, I may have to return the product as I am thinking I would like the spikes shorter but that is no fault of Thmotorsports. Hopefully their customer service is as superior as their ordering and shipping. At this point I would definitely shop there again and recommend them.

These guys did a great job tires delivered two days before expected 2nd order from them both orders delivered in just a few days

Great product. Accurate website description. Fits perfectly. 5 stars for sure

It was good
