well it certainly will be interesting. I am ok with the no additive thing...but the tire limit might be a concern depending on the track and the tire...but it will be the same for everyone. I am not sure how they are going to enforce the no additive thing even with the tires being in compound. How do you prevent someone from "cleaning" the tires just after or just before the run. I guess no one will be allow any sort of "towel or shirt sleeve" near the cars after or before the runs? going to be hard to enforce that I think.
