One thing about the viper is its not a peoples car it had nothing in it. It has no customer conforts just for racing unlike the zr1. From here

"Except for a Racetech seat with a six-point harness, each ACR is factory stock and fitted with the Hard Core package, a no-cost option that cuts 40 pounds off the curb weight. About 10 percent of ACR customers order the HCP, which deletes the audio system, trunk carpet, rear cabin sound insulation, tire inflator kit, hood insulator, and steel battery cover."
Dont get me wrong both are crazy but this wasnt a "heads up race" Take all the comforts out of the corvette and change the zr1 so its not in stock form like the dodge engineers did to the viper and it will be its time.
From that same site
"To address Coronel's complaints that the ACR is displaying light understeer in medium- to high-speed turns and its steering feels a little light, engineers stiffen the front dampers for both compression and rebound (up three clicks to position 11, out of 14 total) and the rear dampers for compression (again, up three clicks to 11). The adjustable rear wing, which offers seven hole positions with the seventh offering the most down force, remains in position three, while the front splitter stays at its initial setting (0) as does the ride height (0.5 inch lower than stock)."
