If you're looking to upgrade your braking game on your B9 or B9.5 Audi RS5, the 034Motorsport 2-Piece Floating Rear Brake Rotor Upgrade Kit is a solid choice. This kit comes with everything you need to swap out those factory rotors for something that actually makes a difference. We're talking about a full 330mm x 22mm rotor setup that fits perfectly with your stock rear calipers, so no need to worry about compatibility issues.
What sets these rotors apart? For starters, they weigh in at around 12.1 lbs each, which is a nice drop from the factory's 13.8 lbs. That 1.7 lbs per corner may not seem like much, but it adds up and helps with overall performance and handling. Plus, despite the lighter weight, these rotors still have enough thermal mass to handle heat effectively, so you won’t be dealing with brake fade when you really need to stop.
The central hat is crafted from 6061-T6 aircraft-grade aluminum, which is both lightweight and super durable. The rotors themselves are made from a unique metal alloy that can withstand high temperatures without warping. And let’s not forget about the 72 curved vanes built into the design. They actively channel cool air through the rotor, helping to keep things cool during those spirited drives.
Another cool feature is the J-Slot design on the friction face. These slots help keep your pads clean and allow for better outgassing of hot materials, which means less noise and better performance compared to standard slotted rotors. And the floating mount system uses high-strength alloy steel bobbins that let the rotor expand and contract safely under heat, so you don’t have to worry about warping.
Fitment:
And just to clarify, this upgrade fits not only the RS5 but also the RS4 from 2018 to 2023. If you're serious about getting the most out of your braking performance, this kit is definitely worth considering. You’ll notice the difference, whether you’re hitting the back roads or just cruising around town.
