Paragon Performance Rotor Rings 378mm x 36mm (14.88” x 1.42”) - P.C.D. 240mm - 12x6.4mm Mounting - D55

Paragon Performance Rotor Ring offers superior braking and cooling efficiency optimized for track and race applications. It features directional ventilation vanes to create suction, turbulence, and guides cool air through the rotor for improved heat dissipation and increased resistance to cracking under harsh track condition.

Made of CM-250 special formulated high carbon alloy cast iron, it allows for an optimal bite, thermal characteristics, high-temperature strength and durability. Rotor rings are heat treated to release stress in the rotor to avoid deformation and vibration then turned by state-of-the-art CBN surface machining to ensure better break-in with new brake pads.

Vibration is reduced as the rotor lateral run-out is kept within 0.03mm and well-balanced: variations are kept within 2 grams. All rotor rings went through rigorous quality control procedures and inspections to ensure the rotor rings are fit for their purposes. The floating 2-piece design allows thermal expansion of the rotor while minimizing deformation and ensuring the rotor is self-centered with the pads. A slotted rotor improves braking consistency by maintaining a clean contact surface and dissipate heat generated and gases released when the pads come into contact with the rotors. Slotted rotors have a superior advantage over blank rotors in wet or raining conditions by preventing water films to form between the brake pad and rotor surface. Weighing less than most O.E. rotors while maintaining proper thermal capacity, our rotors improves overall handling by saving unsprung mass.

Directional ventilation vanes for optimal cooling performance and increased resistance to cracking. Run up to 30% cooler than O.E. rotors and increase cooling efficiency by up to 30%

The pillows have a chemical smell
Size: King (Pack of 1)
I bought two Marlow pillows a while ago. They are great pillows. The two new Marlow pillows I just purchased have a chemical odor. The manufacture date is Sept. 2024. I have them airing out hoping the smell will dissipate , so far that has not happened.

Simply The Best
Size: King (Pack of 1)
It appears there are more than 1,000 pillows advertised and available all over the Internet. The situation is a comedy routine. If you want a cooling pillow because you're a hot sleeper or if you want a plush pillow for back problems or a combination or neither, it doesn't matter. Be prepared to read 1,000 different advertisements until you start laughing out loud. This is what I did, but I wandered upon this Marlow Pillow system and then trusted the Amazon ratings. And boy am I happy, though a word of caution: if you want the cooling technology to really work you've got to pair this pillow with the Marlow pillow protector. Because Amazon didn't carry the pillow protector I bought it directly from Marlow. And this is the last pillow I'll ever get or need to get. Comfortable like a goose down pillow and yet cool to the touch and cool all night long. So I got lucky; have avoided having to buy multiple pillows; and now am enjoying the heck out of my Marlow King with the Marlow pillow protector. Lastly, this pillow is adjustable with a zipper and it works: you can make it softer or harder with a quick zip. The best pillow out there, by far!

Really good pillow!
Size: King (Pack of 1)
This is the first pillow that I have owned in the last 10 years in which I have not experienced any neck pain. It's the right density, comfort level, and is a high-quality item. I am a side and stomach sleeper. Try this pillow and I think you'll be happy.
