I like the new SOD rules, I think its a great idea. I doubt there is a need for new wheels. I talked to one of the guys that tested and he said they ran current wheels, and narrower ones. He said the car was fastest with the current wheels. Makes sense. Even though the current 410 and 360 tires are 16" wide, why is there a 18" wide wheel rule? Because they are better on wider wheels, if they weren't, then there is no need for the rule. If that's the case, there is no cost other than tires for any sprint car out there to race with SOD. This tire rule makes sense to me, narrower tires are going to put less power to the ground, no denying that. If you can only get so much power to the ground, who cares how much power you have. In my opinion, it will make a lot more guys competitive that had good engines, but not the huge budget for a killer one. The RR is smaller, but I think the harder compound and 3" narrower LR is going to take away a lot of traction. Not to mention, only 1 size LR is going to save a lot of money. With the trend of non-wing guys trying more winged shows, I wonder if any will try SOD if they get some Indiana shows. I would think less traction would be right up their alley!
