I apologize. I had edited the "R4 Racing Format" post to include the GTC program but uploaded the old version.
GTC (both versions) will qualify then be broken down into however many heats makes sense depending on number of entries. The format is known as "one and done." After all heats have been run all totals are compared to determine the winner. GTC-FK goes first and the winner is invited to "move-up" to the GTC-Pro class if desired.
Secondly it needs mentioned that F1 requires .812" tires with .050" rear clearance.
Also it is recommended that you bring your "geezer googles," if needed, to tech so you re-pin your body quickly and not hold up the tech line.
