All trucks competing in the Points Series are subject to a tech inspection and all final rulings are at the discretion of the race officials.
In general, if the rules do not specifically say you can do something, either assume you cannot or ask an official for clarification. It is the discretion of the race director/track officials to make the official call. Any attempt to cheat or do anything not within the “Spirit of the Rules” may be deemed illegal.
