If you're looking to step up your braking game, check out the 350mm 2-Piece Floating Rear Brake Rotor Upgrade for your MQB VW or Audi. This isn’t just a shiny upgrade; it’s a full-on replacement kit that’s made to work like a charm with your stock rear calipers. Whether you're hitting the streets, taking a lap on the track, or pushing it at a high-performance driving event, these rotors are designed to keep your brakes cool and responsive all day long.

Weighing in at around 14 pounds, each rotor shaves off a pound compared to the factory 15-pound rotors. Plus, the diameter bumps up from 310mm to 350mm. What does that mean for you? More stopping power and less rotational weight—that’s a win-win! The design keeps the thermal mass just right, so you can count on them to handle the heat without breaking a sweat.

The heart of these rotors is the central hat, crafted from 6061-T6 aircraft-grade aluminum. That means it’s tough and lightweight. The rotor rings are made from a special metal alloy that can take on serious braking temperatures while maintaining their shape. With 72 curved vanes, these rotors work hard to pull in cool air and push out heat, so your brakes stay effective even under pressure.

And let’s not forget about the J-Slot design on the friction face. This setup cleans the pad surface and helps with hot pad outgassing, keeping everything running smoothly. The floating mount system uses high-strength alloy steel bobbins, which allow for some movement between the hat and disc. This flexibility is crucial because it helps the rotor expand and contract safely as it heats up and cools down.

Features:

• Lightweight design at 14lb (compared to the 15lb OE rotors)
• Floating, 2-piece construction for better performance
• Aerospace-grade aluminum hats with Type III hard anodizing
• CM-250 special alloy rotor rings for durability
• J-Slot slotted friction face to keep things clean
• OEM fitment means easy installation
• 72 curved vanes for effective cooling
• Floating bobbins for safety during expansion
• Replaceable rotor rings for lower long-term costs
