Further updates on rules:
Once posted, we anticipate a comments period of approx. 2 weeks after which comments will be evaluated and the final 2008 rules will be published.
As a rule of thumb - we're looking at:
1) Increasing series participation
2) Reducing costs
3) Ensuring level playing field between the various models of eligible cars
Expect to see a lot of detail changes to make the rules more clear and easier to understand, and to reduce contradictions. Also, there will likely be some (pending final approval) changes in weights and how HP/TQ are applied for each model engine.
Also there should be more suspension and wheel options and combinations.

It's got lots of great information on car setup, how to get started in racing, as well as news and other information. Should have some videos from the national championships soon as well.
Please take a look and feel free to PM me for more information.
