Mark,
Take him competitive kart racing. You won’t believe how much fun you both can have. Where else does your teen come to you and say “Let’s go racing”?
I crewed for my son, starting at age 10. Last year at 17 he raced Spec Miata (a lot slower than the shifter karts he raced.) He is now testing in Formula Mazda at under lap record times. Racing will get tamed down a lot for college this fall. First things first.
I recommend taking your kid racing, not both racing. I have seen several dads go kart racing also. It’s not the same experience. This is a real unique opportunity to stay connected with your kid through some difficult teen years. You crew for him in his karts, he crews for you in your cars.
All through middle school the racing was dependent on grades and behavior. We never had a problem but it wasn’t lost on any of the kids when some of the competitors had to come to the track and only watch.
