Well, I learned that my question is a moot point. No mods are permitted in the club I'm joining for the Nascar class. This class is strictly stock Red Cat Lightning EXP Pro versus the same. That one is an asphalt parking lot venue. There is another place that is indoors with carpets and jumps and another with dirt, rocks and steep climbs. There is no one car that meets all opportunities. So which 3 cars should I get? This is a rhetorical question for me because I will only get one vehicle for now, but the answers would still be fun to know.
