If you are going to race at SCCA SE Division races, you just need to go visit the Appalachian Tire truck, which services all SEDiv races. All you need to do is call them a week or so in advance and they'll have whatever you need. Good people to deal with.

If you're going to run IT7, you will need to have Toyo RA1 or R888 tires, since they are the required spec tire in the division. You can run Hoosiers (or anything else) if you choose to run the car as an ITA, but that's really not what you want to do. Unless you have a REALLY fast RX7, you won't stand much of a chance in ITA. Run with us in IT7 - there's a good bunch of IT7s in the division, and most of them are pretty close on speed.

On the cars you have/are looking at, I'm not familiar with the #66. The green and red #10 is probably Trey Forrest's car. I've looked at the car and it is a decent looking vehicle, and I believe has some of the good pieces. But for whatever reason, it's pretty slow - not sure if it's driver or some mechanical issue.

If the only experience you have is the Bondurant school, a track day or two would be a good idea, both to get you extra seat time and to let you check out the car in advance of actually running a race event. Many SEDiv races have a test day on the Friday prior to the race, so you can hit one of these as well, although an earlier track/test day would be preferable, so you don't get a surprise with a new (to you) car the day before a race. Other suggestions are: 1) get started on getting your SCCA license now, assuming you want to hit races in February or March, 2) get a GCR and read it, particularly the parts related to general car requirements and and IT car specs, 3) make sure your car is really ready to go before you take it to the track (nothing is more annoying than fixing problems at the track, especially if you could have fixed them before hand). Along with that, get the annual tech inspection on the car before you go to a race event. Most regions have a pre-season tech session in January or February - check their websites for dates. It's even more annoying to show up for a race and find out you can't run because you failed tech.

If you have any IT7-specific questions, let me know. Hope to see you on track early this year.
