Cory and Rick are correct if you are running the entire double event weekend and your a person who wants a set of fresh rubber each morning.(The serious racer)
If your running Rotax, you run the Mojos you already have and there is no SKUSA membership fee! (As your running Rotax rules, getting punches and cool trophies from SKUSA)
Cadets run MG Reds and one set last all weekend!
Also,, you can enter one .
day for half the cost as there is 2 rounds of practice each day before qualifying.
The Track is selling gas by the gallon and your tires do have to be the SKUSA white but if you have tires from another PKC event that are stamped they are allowed.
So for a one day the cost does drop for those who just want to come out and have fun racing the best on the North Range.
Hope to se ya there!
