Although this would be more relevant to a four wheel vehicle, I have said before and I will say it again, the best thing I did when building my car was to go to Speedweek first as a spectator and look at and visit with the people already running cars in classes simillar to what I was building. You will get honest answers to your questions, and a much better idea of what you need as far as safety, design, and support equipment. Motel rooms are pretty much non existent for Speedweek, so make sure you have a place to stay before making the trip, unless you don't mind driving 100 miles to Salt Lake City.
