I understand the narrow (hard compound?) tire move. But is it a higher cost for less amount of tire? Are they going to limit the amount of tires used in a night? Will this turn in to a tire soaking-grinding party? Will the racer have to spend tons of money on shocks-bars to get that little bit more out of the new tire? So any sprint car in the world can now run with SOD. Last year Rico showed up on a off night. Will they want to buy new (can't use any other place) rims and tires? I would think more likely would pick an other club to race. Don't get me wrong, I really hope it does work, more cars, good side by side, two groove racing.
