If you're looking to take your Gen 1 or 1.5 Audi R8 to the next level, you might want to check out the 034Motorsport 390mm x 34mm 2-Piece Floating Front Brake Rotor Upgrade Kit. This isn't just a simple swap; it's a serious upgrade that can make a noticeable difference in your braking performance.

First off, let’s talk size. These rotors are 390mm in diameter, which is a bump up from the stock 365mm rotors. What does that mean for you? More braking force, plain and simple. And with the larger size, you also get better cooling—something you’ll appreciate on those long drives or spirited track days. Weighing in at around 23.9 lbs, these rotors shave off a bit of weight compared to the factory ones, which clock in at 24.5 lbs. That .6 lb reduction at each corner might not sound like much, but every little bit helps with performance.

The construction is where this kit really shines. The central hat is made from 6061-T6 aircraft-grade aluminum, so you know it’s tough. The rotor rings are crafted from a special CM-250 alloy designed to handle high temperatures without losing form. You won't have to worry about warping or fading here. Plus, the rotor features 72 directionally curved vanes that help channel cool air through the disc, keeping things nice and cool even under heavy braking.

And let’s not forget about the J-Slot design on the rotor face. This isn’t just for looks; those slots clean the brake pads and rotor surface, helping to prevent buildup of contaminants. They also allow for better outgassing of hot brake pads, which means you can enjoy a quieter ride compared to traditional slotted rotors. The whole floating mount system, with its high-strength alloy steel bobbins, allows for some necessary movement during braking, which is crucial for managing heat expansion.

What’s in the box? You’ll get a complete 034Motorsport 2-Piece Floating Front Rotor Pair, caliper spacers, and detailed installation and break-in instructions to get you rolling. This kit is designed to fit the Audi R8 from 2006 to 2015, whether you’ve got the V8 or V10 under the hood.

In short, if you’re serious about enhancing your R8’s braking capabilities, this upgrade kit is a solid investment. It’s all about performance, reliability, and keeping your ride feeling as good as it looks. Plus, with the replaceable rotor rings, you’ll find the long-term maintenance costs are lower than you might expect. Get ready to hit the road with confidence!
