"Super Touring" is the official classification by the SCCA. Call it Super Touring!
I would suggest we start with a single category labeled as such and if board traffic warrants, a breakdown into the sub divisions of "STO" (Super Touring Over 3 liters) and "STU" (Super Touring Under 3 liters). Just one category would do for now. It will be interesting to see how class participation pans out the next year. I'll be running STU all year in the POS-7 just to get some national races experience. Trey and I upgraded our licenses to national status as he will get into STU for at least one event and then in a Vee later in the year sometime.
