After three days of Daytona tests and constant tinkering with the rules package, NASCAR thinks it is close to setting the final specs for the Daytona 500. At least they'll be final until the cars show up for Speed Weeks. Then all bets are off.
IndyCar teams from Honda, Chevrolet and Lotus will hit the track today and tomorrow at Sebring for the first mass test of the year. All three engine brands have already been in action, but this will be the first time for all three to be on the track at the same time.
