If you're looking to amp up your braking game on your Gen 1 or 1.5 Audi R8, the 034Motorsport 356mm x 32mm 2-Piece Floating Rear Brake Rotor Upgrade Kit is definitely worth your attention. This kit is designed specifically to work seamlessly with the factory rear calipers, so you know it’s going to fit like a glove.

Each rotor tips the scales at about 18 lbs, which is a nice little weight savings compared to stock. This reduction in rotational weight means you’ll feel a difference, especially if you’re pushing your R8 to its limits. But don’t worry, they still have the thermal mass to handle the heat generated during hard braking. That’s crucial for maintaining performance and safety.

The central hat is made from 6061-T6 aircraft-grade aluminum, which is not just lightweight but also super strong. The rotor itself is crafted from a special metal alloy designed to withstand those high braking temperatures without losing its shape. Plus, the 72 directionally curved vanes are a game changer—they help channel cool air through the rotor, keeping things nice and cool when you’re really on it.

Now, let’s talk about the rotor face. It’s got J-Slot slots that do a great job of cleaning off any brake pad dust and debris, which means better contact and less noise compared to traditional slotted rotors. And if you’ve ever experienced that annoying squeal, you’ll appreciate this feature.

The floating mount system is another highlight. It uses high-strength alloy steel bobbins that let the rotor and hat move independently, which helps manage the heat expansion and contraction during use. This means you can push your brakes hard without worrying about warping or other issues.
