The front spoiler ( air dam ) certainly helped in the standing mile races . I have had more trouble with the back of the car getting light. In the Oct 1/2 mile I had to put on the rear deck with the spoiler . Concerning power to weight : my car is 4.25 pounds/HP , the Z06 ( 600 hp ) was around 5.1 pounds/HP . Better aero didn’t help , he couldn’t catch me. Later in the day I ran another Z06 with a reported 720 hp , so about the same power to weight as the Tiger . In that race I stayed close till second gear ( when the Corvette could get traction ) , then he just pulled away.
