B are you going to allow 17.5 brushless in the stock class in addition to optional tires? Also, optional tires make a HUGE difference so maybe there should be some limitation there so new folks coming out with truly "box stock" SC trucks aren't stuck spinning donuts (and frustrated) on their stock tires while the next guy (who spent $50+ on new wheels and tires) is sticking to the track like glue. Not trying to confuse the issue...just throwing that out there. How are other places like G's handling their SC setup rules for the different classes?
