I'm all for kids racing.I have one that started in mini stocks at 12 years old and dirt late model at 13. My problem with that is if a fullsize car is in the othe lane and hits him it could be bad. Sounds like if they'll let him make a pass in his mom's car he should be racing a fullsize raccar and just keep stepping the engine up as you go. Be smart and keep him safe but let him have fun!
