In 2012, there were very few 86's, track day notice went out, and it was easy to sign up.
You rode shotgun in one of Toyota's Scion FRS on the Gran Prix track, and drove autocross with an instructor with your own twin .
The new notice was probably filled within minutes of posting due to the larger number of owners now.
But - they will be strict on mods, (cannot remove a cat etc.) and many spots I'm sure were booked by owners with mods and will be D Q'd on arrival.
It's likely that its an advertising venue for the SUPRA to get us horny for it.
