Racing-Grade High-Carbon Steel WaveSlot Brake Rotor Friction Ring
A racing-grade high-carbon steel brake rotor friction ring built for repeated high-heat cycles, stable pedal feel, and consistent friction behavior across demanding track sessions.
Engineered for Track Heat
This rotor friction ring is designed around controlled heat management and friction-face stability. The high-carbon steel formulation helps improve resistance to distortion, heat checking, and stress-related cracking that can appear when standard replacement rotors are pushed into competition use. The result is a more predictable pedal and a friction face designed to hold up across long brake events.
WaveSlot Friction Surface
The WaveSlot pattern is machined to keep the pad interface active by creating repeated leading edges as the rotor turns. It helps evacuate brake dust, gas, and surface contamination from between the pad and rotor, supporting a more consistent contact patch during aggressive braking. Pair with the correct race pad compound and a proper bedding procedure for best results.
Key Features
WaveSlot Friction Face
Machined slot pattern helps keep the pad interface active and supports debris evacuation.
Precision-Machined Surface
Designed for low runout and consistent pedal feel when matched with the correct hat and caliper setup.
Track-Focused Durability
Designed to improve resistance to heat checking and stress-related cracking under load.
Two-Piece Assembly Ready
Suitable as a replacement friction ring for existing competition setups or custom two-piece rotor assemblies.
Specifications
| Brake Rotor Friction Ring | |
|---|---|
| Product Type | Racing-grade brake rotor / friction ring |
| Material | High-carbon steel |
| Friction Face | WaveSlot pattern |
| Intended Use | Track and competition braking |
| Configuration | Friction ring for existing setups or custom two-piece assemblies |
| Recommended Pairing | TTSPORT billet aluminum rotor hats; race-compound pads |
Exact diameter, thickness, vane count, and bolt pattern depend on the variant selected. Confirm dimensions against your existing caliper and rotor hat before ordering.
This product page describes the racing friction ring only. Rotor hats, bobbins / mounting hardware, brake pads, calipers, brake hoses, and complete two-piece rotor assemblies are not included unless separately specified on the final order.
Two-Piece Build Ready
This rotor is offered as a friction ring, making it a direct option for drivers replacing worn rings on an existing two-piece assembly or building a custom configuration. Combine it with TTSPORT billet aluminum rotor hats to complete a serviceable, weight-optimized two-piece rotor.
Service & NVH Notes
- Bed-in with the matched race pad before hard track use.
- Slotted friction faces are intended for performance use; expect more pad-rotor noise than a smooth street rotor.
- Inspect for heat checking and thickness variation between sessions.
- Check friction ring thickness, surface condition, and mounting hardware condition according to your track service interval.
Frequently Asked Questions
Is this a complete two-piece rotor?
No. It is sold as a racing friction ring. Pair it with compatible TTSPORT billet aluminum rotor hats to build a complete two-piece assembly.
What material is used?
High-carbon steel, chosen for thermal stability and resistance to heat checking under repeated high-heat braking cycles.
Will the WaveSlot face increase pad wear?
Slotted friction faces typically wear pads faster than smooth rotors. That is expected on a track-focused rotor and is the trade-off for active pad interface and debris evacuation.
Can I use street pads with this rotor?
It is designed for race-compound pads. Street pads will work mechanically but will not deliver the heat tolerance or friction stability this rotor is built for.
How do I confirm fitment?
Diameter, thickness, and bolt pattern vary by variant. Verify dimensions against your caliper and rotor hat, or contact us with your setup details.
Need help matching this friction ring?
Send your rotor diameter, thickness, vane type, bolt pattern, rotor hat spec, caliper model, and pad compound. TTSPORT will help confirm whether this friction ring matches your setup.

Is this a Casper or Tempurpedic?
When I went to wash the pillow covering I discovered that it iterally had a Tempurpedic factory pillow covering underneath the Casper factory pillow covering - leading me to believe that it was either a return item shipped out as new, and the previous owner actually returned a Tempurpedic pillow disguised as a Casper, or Casper is actually manufactured by Tempurpedic and uses the Casper brand to upcharge. Either way - it's turned out to be an overly expensive - mediocre pillow.

Does not cool, is hot actually
I am very disappointed with this product. I write a lot of reviews and give credit where credit is due. I wish credit was due here.
I bought this as a gift for my wife. She slept on it for a few nights and finally stated that it never cools and is hot instead. And so I tried it and found the same thing. I bought an inexpensive cooling pillow from Costco and we both found that one to cool a little bit and it isn’t hot.
I’m summary, you don’t always get what you pay for and at $100, this pillow does not deliver. It’s supportive and it seems well made, which is why I give it two stars. But it does not deliver any cooling. Save your money and try a different pillow.

Does what it claims, supportive and eliminates heat.
Size: King (Pack of 1), Style: Single Pack
Its a bit pricey however when it comes to sleep quality im glad to pay for name brand. No tossing or turning to escape to the cold side of the pillow. Feels firm which was concerning at first however once you settle in its very comfortable. Seems to be just how foam pillows are made. Happy with the purchase.

I have found the PERFECT pillow for me!!!
Size: King (Pack of 1), Style: Single Pack
I just absolutely never write a review on anything, but I have to praise this pillow from the rooftops! I have not slept this comfortably is so many years! I have plushness and support, my neck is in alignment, and when I turn to sleep on my side the pillow doesn’t block my airflow. This pillow is perfectly made for me!!!!

Super comfy
Color: Soft, Size: Queen(28"×16"×5.9")
Absolutely love this pillow! It’s incredibly soft, supportive, and stays cool throughout the night. I’ve been sleeping much better since getting it. Great quality, perfect firmness, and definitely worth every penny.
