1.080 delay and .000 reaction time on a full tree means a .020 on a .400 pro tree. I think it's perfect, red lights don't win rounds.
If you want to have red lights, try something that will lift the front tires off the lights instead of driving out of them. Maybe even ballast in the trunk would do the trick? What kind of weight distribution does the Vette have?
Jerry Bickel's chassisbook said that long and low IC reacts slowest, but keeps the tire planted longer time.
