034Motorsport 2-Piece Floating Rear Brake Rotor Upgrade for Audi C8 RS6 & RS7 - 034-301-2026
This 2-piece floating rear brake rotor upgrade replaces the factory rear rotors on the C8 Audi RS6 and RS7 with 370x30mm rotors that work with the factory rear calipers. Each rotor weighs about 22.7lb against 24.7lb for the factory part, combining a 6061-T6 aluminium hat with a CM-250 alloy ring that keeps enough thermal mass to absorb heat. Where the factory uses the same straight-vaned rotor on both sides, 034Motorsport's rotors have 72 directionally curved vanes handed for left and right, plus a J-slot face that cleans the pads and vents gases with less noise than a traditional slotted rotor. The ring floats on high-strength alloy steel bobbins to allow for heat expansion and can be replaced separately when worn.
