What races around Texas will you be running? My daughter runs cadet at our club (HCKC) and in the Texas Sprint Race Series. It’s a 245 lb min weight for that class in those races, which I believe is also SKUSA’s min for that class. We typically come in anywhere from 247-252 in weight after each race. Race ready, our kart weighs around 160 lbs. right now with 10 lbs of ballast added. We’ve raced with a few kids that have no problem making weight, and have no weight added to their kart, so you’re not alone.
