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 Fast & the Curious- Potty Drift
Size: 5T-6T, Unit Count: 60
Who knew toddler potty training required both a PhD in fluid dynamics and Jedi mind tricks? These Pull-Ups prove the science part: leak-proof, absorbent, and surprisingly soft. The toddler-psychology part? That’s a battle of wills. Our little one was a die-hard fan of Huggies diapers—too loyal, in fact. We begged, we bribed, we pleaded: “Please, let’s move on!” Resistance was fierce. So we went stealth mode, sneaking Pull-Ups on at night like parents on a covert mission. Credit to mom—she cracked the code and finally got the kid interested in the toilet. Suddenly, the “potty rush” moments became less of a flood and more of a sprint. Diapers were too slow to peel off; Pull-Ups gave our little sprinter the speed boost they needed. They’re soft, rash-free, and practically leak-proof (unlike that other brand we don’t speak of). Pro tip: size up for easier toddler self-removal. The result? A drier, happier kid, less laundry for us, and the toilet finally earning MVP status. If you’re ready for your toddler to graduate from Diaper University, this is the diploma. Bonus: you’ll save money too.

Mom of 3 recommend!
Size: 5T-6T, Unit Count: 14
I'm using these again for the 3rd time and they're great as always. My 3rd is still having some issues at night time with bed wetting, and as they get older the bigger the mess, so these truly hold up to a full bladder. And they don't smell by morning like some diaper brands. I'm usually against pull ups, but these are great for up and down ease of use and that added protection when it comes to potty training. I love the bigger size inclusion for larger children which we struggle with for comfort compared to other brands.

Healthy Sea plant magnesium
I’ve been researching magnesium and ran across the benefits of magnesium from sea plants. Since many people lack the proper amounts of magnesium this type of magnesium seems healthier than magnesium from the earth.
