The 034Motorsport 350mmx34mm 2-Piece Floating Front Brake Rotor Upgrade Kit for the B9 & B9.5 Audi S4/S5/SQ5 is a complete replacement brake rotor kit, designed to work flawlessly with the factory front calipers found on the B9 & B9.5 S4/S5/SQ5. Weighing in at approximately 21.25lbs, each rotor reduces rotational weight by 6.65lbs per corner over the factory 27.90lb rotors! While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture heat, while utilizing 72 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.
