I am thinking you have to run pirelli to enter the race seeing you have to post tech to enter.Maybe they will pay tire contingency and purse, plus maybe the tires will be discounted ? Then you could win a little money.Maybe Dunlop,Michelin, Bridgestone, tire contingency will be less of a pay out per class then running this one race?If you dont have a tire contract it may be for you.I guess do what benifits you the most.
