As noted on ChampCarStats.com, some race information is missing and the car number is one of them so this isn't a comprehensive list with every single race accounted for. This is a list of what we have and that is a fair amount.
If you notice any discrepancies, let me know on Twitter. I plan on updating this list as the upcoming season progresses.
