The idea of the GT class is to make a place where no matter what type of kart, engine, type of equipment, or how old you are, what you can afford, you can be competitive and have some fun. Many long time carters (such as Rick Neal, George Damanic, Mark Suchan, Adam White, Jay Chapman and others) are endorsing this effort to bring some financial sense back to karting and more competitive races with more entries.
