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%

Eufy l50 SES
Style: L50 SES
Works great, easy to setup. It's my second unit for the basement level. Picks up all the fur from a large Rottweiler and a small Rat Terrier.

Not worth it
Style: L50 SES
Worked great for 5 months and then the WiFi connectivity stopped working rendering the vacuum useless. Because it’s refurbished it was past its warranty and the company refused to do anything about it other than offer a discount on a product that cost four times as much even after the discount.

Great vacuum, but it only works on 2.4 GHz Wi-Fi
Style: L50 SES
I missed the last line on the description that states in only works on 2.4 GHz Wi-Fi. I have AT&T fiber and the router they installed only runs on 5.0 GHz. The vacuum still works, but without all of the fancy conveniences. Just be aware of this and if you are not familiar with what it means, check before you purchase one. This is the only reason I am giving it a 4 and not a 5. It is my fault for missing it, so just be aware.

Great vacuum!!
Style: L50 SES
I love this vacuum. I had to work a little to get the map right for it, but it is great. We have allergies and it helps so much and saves so much time. It does take a while to do the whole house, but I have it programmed to run while we are at work and it’s so nice to come home to a freshly vacuumed house.

Eufy dropped the ball on this vacuum
Style: L50 SES
I’ll start by saying the reason I purchased this vacuum, is because I have a Eufy 25c robot vacuum that is very dependable. I decided I wanted an upgrade because the 25C was great for cleaning, but I had to empty it way too often. I just knew I would love the L50 SES. I thought it was just what I was looking for a self emptying robot vacuum with a 60 day fill capacity. Allowing 2 months before I needed to touch my vacuum. Here’s where things went wrong. I never got a chance to test the vacuum because it wouldn’t connect to my WiFi and I tried everything. Now this wouldn’t have been a problem if the L50 came with a remote control like the 25C. Unfortunately I had to rely on the App and since the L50 couldn’t connect to my WiFi, I couldn’t control the vacuum. The reason I gave 2 stars is because the customer service at Eufy is awesome. I was given the option to replace the vacuum with a new one but after researching the L50 i decided to return it for a refund. Apparently this model has a defect, because I found so many negative reviews about the same issue with the same model. The thing is I never read reviews because I have a Eufy smart scale, 25C robot vacuum and an Eufy security system and everything works perfectly. So in the end I purchased a Shark Matrix Self emptying robot vacuum and a Shark self emptying stick vacuum. If Shark’s vacuum preforms well, Eufy might have lost a valued customer. I hope this review helps someone make a informed decision. By the way Eufy self emptying vacuum needs replacement bags and the Shark Matrix robot vacuum doesn’t need bags. I will say the suction and design on the Eufy L50 SES was great.
