Product Details

The R1 Concepts 633-31184D is an RNC Series drilled and slotted disc brake rotor engineered to deliver enhanced stopping power, improved heat management, and long-lasting durability over standard OEM replacement rotors. Designed as a direct-fit upgrade, it installs without modification to factory brake hardware.

Cross-Drilled Design: Precision-drilled holes are countersunk and chamfered to reduce heat stress and minimize the risk of cracking. The cross-drilled pattern allows heat to escape efficiently, helping to lower rotor operating temperature and reduce brake fade under repeated or hard stops.

Diamond Slot Technology: The exclusive diamond slotted pattern increases brake pad bite and continuously sweeps away brake dust, gases, and road debris from the rotor surface. This prevents pad glazing and extends the service life of both the rotor and the brake pads. The diamond-tipped slot ends also serve as a built-in wear indicator—when the tips are worn flush, it signals time for rotor replacement.

Corrosion-Protective Coating: Each rotor ships with a zinc plating applied to the hat, vanes, and non-braking surfaces to resist rust and corrosion, maintaining a cleaner appearance over the life of the rotor. The coating on the braking surface wears away naturally during the break-in process.

Key Features:

  • Cross-drilled and diamond slotted one-piece rotor construction
  • Countersunk, chamfered drill holes to resist cracking
  • Diamond slot pattern prevents pad glazing and removes debris
  • Built-in wear indicator at diamond slot tips
  • Zinc-plated coating on hub and vane structure for corrosion resistance
  • Direct OEM-spec fitment — no modifications required
  • Suitable for daily driving, street performance, light towing, and hauling

Always follow a proper break-in (bed-in) procedure when installing new rotors, and replace brake pads at the same time to ensure optimal rotor contact and performance. It is recommended to use brake pads compatible with drilled and slotted rotors.

I've had nothing but oof experiences doing business with THMotorsports. Best price for spark plugs out of anyone else. Fastest shipping with reasonable rates.

Fast delivery!

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.

So good so far ,

You had what i was looking for

Great prices and a surprisingly fast delivery, which despite choosing the most economic choice (2-14 days), I received the items in 5 days - saved more than half in shipping. Great all around experience and great product extremely well packaged. Thank you, folks!

I had to email customer service for the invoice and they got back with me immediately

Fast and easy ordering.
