Paragon 2-piece Rear Rotors For M2 (F87) / M3 (F80) / M4 (F82/F83) with blue calipers
Paragon Performance 2-piece Rotor 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 rotors went through rigorous quality control procedures and inspections to ensure the rotors 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 2-piece rotors improves overall handling by saving unsprung mass.

Aluminum hats are CNC machined from lightweight 6061-T6 aerospace grade aluminum for high strength and durability under extreme track conditions, then black hard coat/hard anodized to increase resistance to wear and corrosion. Mil-spec Type III anodized hats will not discolor under extreme heat, and are harder and more wear/scratch resistant. Unnecessary materials are taken out from the aluminum hats for maximum weight savings while maintaining proper structural integrity. 
*Black hard coat and hard coat anodized hats are the same in terms of performance and durability.

Direct bolt-on without any modifications and designed to work flawlessly with OEM ABS and brake system while maintaining factory brake bias. Compatible with OEM brake pads or aftermarket pads with the same pad depth (D)

Directional ventilation vanes for optimal cooling performance, runs up to 30% cooler than O.E. rotors and increase cooling efficiency by up to 30%

Floating 2-piece design

Minimizing brake fade & judder during extended sessions

Utilizes OEM E-brake by integrating iron sleeve into aluminum hat
Weighs 19.6 lbs (8.9 kg) - save 1 lb of unsprung weight per rotor vs. OEM
Rotor to hat mounting system: D-Bobbin (long) - 10 bolt

Excellent for heavy chewers
Excellent toy for heavy chewers like malinois! The rope makes it easy to throw farther. Good amount of bounce as well. Definitely need to supervise as it could be a choking hazard for larger breeds.

Rope breaks toy breaks, buy it anyway?
3 stars. 4 stars during the 5 months it worked. 2 Star now. The rope bites through easily & often. I could hobble the rope together the first 5 months (see how it's shorter) now toy is a dud. Durability 1 Star. Took my 6 month old puppy a few minutes to do this. You see, she chewed threw it a few times and I was able to re-tie it until I ran out of rope. She DID love to do the puzzle- carrying it around, banging it on the ground repeatedly, tugging the rope gently up and down, holding the rope while shaking the ball like a pendulum side to side, rolling it with her paws like a cat, holding the rope with her teeth and banging the ball into various objects around the room trying to dislodge Stella and Chewy Meal Mixers... She's very clever and not at all a brut. I would give this to her for ten or fifteen minutes before bed. She still likes it and it still sort of works? She can no longer pull up and down on on the rope or carry it or around or bang it against various objects. So, you basically have a ball now with treats that can super easily fall out. You can just give your dog a regular ball with no hole and throw a handful of treats on the ground. I DO recommend buying this though. My dog loves it.

Greatest toy for GSD!
My German Shepherd LOVES LOVES LOVES this thing. I’ve purchased about 5 of them, not because they don’t last (they do), but so we can have them everywhere (one in each car, the backyard, the front yard, the house…). The string makes them so easy to throw far and you don’t have to handle a sloppy foamy tennis ball. And it’s great for playing a little tug. All in all, a winner of a product!

Good Toy Reward for Training
Size: Medium, Size: Medium
A great non-food reward for dog training and play! It’s the perfect size for my German Shepherd and the tie makes it easy to carry and play tug. It’s also been very durable for her sharp teeth!
