Don't get to hung up on how many sets of tires you can run. The traction is great at SRS and you don't need new tires every 2 runs. The winner of both stock classes at this years Cactus ran the same set of tires through qualifing and the mains. The handout tires are the best choice for that track and there should be no issues.
Due to it being a level 4 race, you must purchase a full membership. If you have already within a year purchased a single event membership, you should be able to get the single event membership because they allow two single event memberships to combine into a full membership, but the date on the full membership will be that of the first single event membership purchase.
(kind of confusing if you have raced at a roar race within a year of this race and purchased a single event membership)
Roar does not control how many tires or what tires you use for practice. If you practice enough to use up 10 sets of tires or only 1 set of tires, it is all good.
thanks for the quick reply. so, basically, what your saying is its going to cost me about $100 to enter 1 race, not including gas, hotel, food, the other set of tires, fresh packs, parts... right? MAN! i need a job!! lol
