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%

perfect fit for the L40 Ultra
Color: L40 Ultra Accessories
I'm very pleased with this accessories kit. All the included items work perfectly with the L40, and are good quality, fit correctly, and cause zero issues. They install just as the OEM items do, and the L40 works exactly the way it did when it came out of the box. I was particularly pleased that even though it's a replacement, it came with another little screwdriver, as I'd misplaced the original. These hepa filters fit snugly, stay in place, and work to take up dust and trap it rather than just spread it around the house. The mop pads appear to be good quality and get the job done. I like how they attach - easy to put on and take off, just like the OEM, so I can clean them easily and use them for a little longer. The main brush is so close to identical that I can't really tell them apart, and they work as advertised - little wrapping and tangling, and they deal with dog and cat hair without a hitch. In all, this is a good value for replacement components that work and are good quality. Recommended.
