Tennessee Classic Car Racing Association
2008 Rule Book

These rules lay out what can or can not be done. Anything not stated that it can be done, or you find questionable and expand on it, will be considered illegal at the time found even if the rule is changed to approve it at a later date. These racecars are intended to be as identical as possible, much like the "IROC" series cars. It is the skill of the driver and the knowlege of the science of suspension setup that determines the true champion and not the depth of the wallet. If anything is found illegal before a race starts, you will be told what you need to do and by when. If you are not sure, have officials check your car prior to the race. There will be no discussion if you are found illegal. If these rules say you can't do it, it is illegal. If these rules say you can do it, it is legal.
