These are the vehicle rules only, the rest of the safety rules (harness, helmets, window nets, etc.) can be found under one of the other vehicle sections as they are all the same
The Formula Toy competition series is designed to be a low cost driver’s class and the rules are written in an effort to keep it that way. You start with a 2 wheel drive or 4wheel drive Toyota pickup. The point of the class is to replace the truck cab/bed with a tube chassis and compete with a basically stock frame and running gear. If you imagine you’re starting with a stock vehicle as your donor, the rules are more like guidelines as to what is permitted to be changed from stock. Don’t look for loopholes because there are none. If the rules say you CAN do it...then you can do it. If the rules don't address a particular modification, you can assume it's not going to be permitted.
