Product Details

The R1 Concepts 623-48036L is a cross-drilled disc brake rotor from R1 Concepts' RNC (Rounded Notch Curved) Series, designed as a direct-fit, driver-side (left) replacement rotor. Engineered for drivers seeking improved braking performance over standard OEM rotors, this rotor delivers enhanced stopping power with a sportier appearance.

Key Features:

  • Cross-Drilled Pattern: Precision-drilled holes are countersunk to maximize heat dissipation, reducing rotor temperature and minimizing brake fade during repeated or heavy stops
  • RNC Series Design: Features R1 Concepts' rounded notch curved slot geometry, which increases brake pad bite and helps expel heat, gas, and debris from the rotor surface
  • Direct-Fit Replacement: Engineered to OEM specifications for a bolt-on installation with no modifications required
  • Left/Driver-Side Application: Sold as a single rotor for the driver-side (left) position — denoted by the "L" suffix in the part number
  • Corrosion-Resistant Coating: Finished with a protective zinc coating on non-braking surfaces to resist rust and maintain a clean appearance behind the wheel
  • High-Carbon Iron Construction: Manufactured from high-grade iron for durability, consistent performance, and resistance to warping under thermal stress

R1 Concepts rotors are machined to precise tolerances and undergo rigorous quality control to ensure consistent pad contact and smooth pedal feel. The 623-48036L is compatible with standard brake pads; however, R1 Concepts recommends replacing pads whenever new rotors are installed to ensure proper break-in and optimal braking performance.

Really like my new front lock for loading my boat. Works great.

Prior to purchasing I made an inquiry and recieved no response.

Good job

Quick delivery and product is looking good but have not installed yet.

I didn't use boatplicity.com for customer assistance, but the "contact us" section. the unit isn't, hasn't nor was it working as designed. air blows, but it isn't even close to warm air.

fast shipping, Thanks!

I received exactly what I ordered and shipping was on time

I bought my item from them due to the original site I bought from kept telling me my item was back ordered and didnt know when they would have one. It was easy and painless to order and received my item in a timely matter. The price was good especially seeing what other sites were charging, not the lowest price but we'll worth the extra 20 bucks I paid. Will buy from them again if they have what I need.

Good
