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%

Coach Quality Never Fails
Size: One Size, Color: Black 1, Size: One Size, Color: Black 1
I'm not sure why there are any reviews complaining of silver hardware or size as that information is clearly listed in the product descriptions. One also needs to order directly from Coach and select the gift option to get the gift box and dust bag, which has always been the case. This Tabby is the perfect size to hold the contents of your wallet, your phone, and your keys. It's a clutch bag. The bag I received has silver hardware and full grain leather as advertised. It's a beautiful, quality bag and the difference between this and a fake is clear; the material feels durable and soft at the same time. The bag smells like leather. Ultimately, as I read and did my research, I'm very pleased with my purchase. I've dressed it up with a cheaper, smaller strap as I'm using this as an oversized wristlet at the moment; but I got everything I paid for.
