I never was good at history mind you, but if memory serves the SCCA contract with Toyo concluded at the end of the 2011 season, NASA was contractually tied to Toyo through the end of the 2012 season. Thus it was actually the other way around, the SCCA had the choice to remain on the same tire and decided to go to Hoosier. In regards to who is getting paid what, I would have to imagine Toyo paid a "fee" to the SCCA to be the spec tire during their contract and Hoosier is doing the same today, that is how those relationships tend to work regardless of whether you are a business or a non-profit.
Dont want to get into a NASA/SCCA deal here.. BUT
SCCA contract came up and the Hoosier tire was chosen by the BOD after a membership survey was sent to EVERY SM competitor. They chose the tire that best matched the wants and needs of their membership. Not shaving and trackside support were some of the biggest concerns. Toyo at that time did not offer either. Still track side is non existant for the most part. SCCA had only one choice or they could choose to ignore the membership. That is one of the benefits of a club.
In NASA, Jerry chose the tire that made business sense, which is what he should do. I am sure he would not have chose Toyo if it was a terrible tire just because they wrote him a check. That would be a terrible long term business decision and Jerry is obviously a smart man. One of the benefits of being a business and not a club, some times a business can protect their members from themselves. A decsion was made at the end of 12 season by NASA not to be on the same tire as SCCA, The decision in 11 was made by what the SCCA membership wanted. It is really a different story, but you can spin however you like.
It will be interesting to see what the SCCA does next year. I would encourage all the SM drivers that are not happy with the rate of tire consumption/competitive cycles to write the BOD and tell them so. Usually we do nothing and then just complain on a forum. The rate we consume tires is too fast IMO and is not needed or reasonable. I do not like the amount of new tires we go through at all. Hopefully the SM7 will be better than the SM6 in that regard, but we didnt see that in the test' Hopefully real life applications will produce better results. If they don't, we need to voice our frustration or sit quietly when nothing is done. Despite the opinion that front runners always happily run stickers etc. I can assure you NONE OF US like buying sticker sets after stickers sets.
