034Motorsport Audi B9 RS4/RS5 2-Piece Floating Rear Brake Rotor Upgrade Kit - 034-301-2010
This 2-piece floating rear brake rotor kit is a 330mm x 22mm replacement for the factory rear rotors on the B9/B9.5 Audi RS5, and the title also names the RS4. Each rotor weighs approximately 12.1lbs, which 034Motorsport says is 1.7lbs less per corner than the factory 13.8lb rotor, while the rings retain enough thermal mass to capture and dissipate heat. The hat is made from 6061-T6 aircraft specification aluminium and is joined to a CM-250 alloy rotor ring by high strength alloy steel floating bobbins that allow safe expansion and contraction from heat. The rings have 72 directionally curved vanes and a J-slot friction face, and they are replaceable, which 034Motorsport says lowers long-term maintenance cost.
