PRODUCT DESCRIPTION:

The 034Motorsport 330mmx22mm 2-Piece Floating Rear Brake Rotor Upgrade Kit for the Audi B8 & B8.5 S4/S5 is a complete replacement brake rotor kit, designed to work flawlessly with the factory rear calipers found on the B8 & B8.5 S4/S5.

Weighing in at approximately 12.15lbs, each rotor reduces rotational weight by 4.50lbs per corner over the factory 16.65lb rotors! While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture, and dissipate heat.

The central hat portion of the 034Motorsport rotor is made of 6061-T6 aircraft specification aluminum. The disc is constructed out of a proprietary metal alloy that can withstand immense braking temperatures while holding form. From the factory, the same straight-veined rotor is used on both sides of the S4. The 034Motorsport rotors utilize 72 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat and are unique to the left and right axle to provide a substantial increase in cooling efficiency over the factory rotor design.

The face of the rotor utilizes J-Slot slots to clean the pad and surface of contaminants and allows hot pad outgassing, all while reducing overall braking noise compared to a traditional slotted rotor.

The rotor and hat have a floating mount system that utilizes high strength alloy steel bobbins. The pins take the load from braking events while maintaining the axial and radial float between the hat and disc, allowing for safe expansion and contraction from heat.

FEATURES:

  • Lightweight Construction (12.15lb 034Motorsport Rotor vs 16.65lb OE Rotor)n
  • Floating, 2-Piece Designn

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.
