I switched to the Carbotechs on my old RX7 and the difference in pedal feel was very noticable. Got better wear than the Hawks and they stayed good down to the backing plate. Ran 7 hours of the VIR 13 and they still looked fair when they came off. Well worth the money. Have not tried some of the newer Hawk compounds, mine were Blue/Black. Tried Hawks at CMP this year and the car was crap under the brakes.
