General Car Rules
I was perusing the Internet to see what advice and information other web sites said about these topics. There are some miss conceptions out there. I will separate the wheat from the chaff for you. Although, you may not like what I tell you, there are no magic setups. Each car/track setup has to be tuned on a race by race basis, especially on dirt.
The topics in the left hand menu are arranged in order of importance. Generally, if you don't have the first ones set correctly, the later items are not going to work as expected. Thankfully, once you get the main topics adjusted, they don't need to change much from race to race. However, they will change from track to track. It is a matter of how much effort you want to put into your racing; keeping records of what worked at what tracks in what weather.
And I'm assuming here that you have read the Car Theory or have a general knowledge of Camber, Castor, etc.
These topics must be studied as a whole, they are intertwined, it is going take some study and practice to make it all come together.
Also, the website does not tell you exactly. I'm just lying out the general information.
The Spirit of the Rules.
Rules are put in place for a reason. The rules maker knows that you will have an advantage if the minimum or maximum of the rule is surpassed. It is in your best interest to understand the rules. Once you understand the rule you may figure out a way to circumvent "the spirit of the rule." Your ingenuity may go noticed or not.
An example, Handsome Harry Gant won 4 races in a row in 1991, before NASCAR figured out how they where not in "the spirit of a rule." The particular rule stated that you must use a standard live axle rear end. Someone in Harry's team figured out how to put toe-in in the live axle. Now there is a rule against toe-in at the rear of the car.
