OK...just talked to the track manager and here is the schedule of events for Saturday, November 22nd:

11:00am - Gates Open
12:00pm - Qualifying Runs/Test & Tune begins
4:30pm - Mandatory Drivers Meeting for ALL CHALLENGES
5:00pm - Eliminations begin

You have to be at the track and ready to get tech'ed in before 4:30pm. If you are not at the drivers' meeting, you will not be in the Challenge. If you miss the Qualifying, but make it in time for the Drivers' meeting, you can still race, you will just be racing "blind" as you won't know what to dial in on your first run.

The way the Qualifying Runs/Test & Tune will be run is the Challenge Drivers will get a qualifying run, then the Test & Tune will run. Once the Test & Tune runs are done, then it will be back to qualifying runs for Challenge drivers. This will continue until 4:00pm or so. This gives the possiblility of more than 2 qualifying runs (3 or maybe even 4 qualifiers, depending on the number of Test & Tune cars). Challenge drivers will get a minimum of 2 qualifiers...as long as you are there and tech'ed by 12:00pm. You can come later and can get in your qualifying runs with your Challenge Class, but you may not get 2 runs in, if you miss any of your Challenge Class qualifying runs.

Corvette Challenge
GM Challenge (any GM except Corvettes)
Truck Challenge
Mustang Challenge
Mopar Challenge
Z Challenge (open to: 240Z, 260Z, 280Z, 300Z, 350Z)
