These Hawk pads will fit on any C5 with stock calipers. They dust like crazy and are not meant for the street. If you’re doing a lapping day or hard core autocrossing (sticky tires and good driver) these are the pads for you.
Fronts and Rears $200
Fronts: HB247 G575 .515" thick including the backing plate. Because the stock calipers flex they do have some taper. The measurement is at the thinnest spot.
Rears: HB458 G650 .58" thick including the backing plate
