Paragon 2-piece Front 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 fully-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%

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing. He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.
