CEIKA 2-Piece Oversized Rear Disc/Rotor Upgrade Kit for Audi S4 B8 quattro (08~15)

CEIKA 2-piece oversized rear disc/rotor upgrade kit for Audi S4 B8 quattro (08~15). This vehicle-specific kit increases the rear rotor diameter while retaining the original rear calipers, brake-pad format and hydraulic brake lines. The larger effective radius increases rear braking leverage and rotor thermal capacity, while giving the rear brakes a fuller appearance behind larger wheels without converting to a complete rear big brake kit.
