Re the banking (31 deg) at Daytona...
As a NCM member in 1999, we were invited to attend the inaugeral 24 hrs of Daytona race as a guest of 'Corvette and Chevrolet', and to follow the Pace car (a Corvette) during the pace lap in our Corvettes. I was driving my 1990 ZR1 as we followed the Pace Car around the track (at about 25-30 mph). Even though we were 'told' NOT to drive up onto the high bank, I couldn't resist... and I found at that low speed, the car really wanted to steer down the bank, so I had to steer pretty hard UP the bank just to maintain myself on the banking. I didn't stay up there long, but wanted to take the opportunity to do it!
Corvette Racing's first event at Daytona International Speedway was in 1999 at the Rolex 24 At Daytona, marking the beginning of the modern era of Corvette racing. The C5.R, which stands for "racing", debuted at the race and was a regular competitor in global GT racing for the next five years. The team ran a six-hour test at Daytona over four days to simulate the 24-hour race, and Doug Fehan led the car into the race. Although the C5.R led the GT2 class for most of the race, engine issues caused them to finish in third place. Despite this setback, GM executives were impressed with the car's performance.
