Nascar cup cars have been at Daytona for a week now. Trucks race tonight and Xfinity cars tomorrow, I'm shure Racing electronics has the list but I don't want to pay for it....lolYou can try speedwaydigest.com/, or jayski.com.
I can't confirm if these are up to date.
Also, I couldn't find any listings on jayski, but they have posted them in the past. They may be waiting for the season to start to confirm accuracy.
