My math. . .
Spec tire raceday. . .
Racer X buys 3 pair of spec tires for todays race ( 1 for practice, 2 for the race). Track has the sale of 3 pair of tires.
Nonspec raceday. . .
Racer X buys 1 of 3 or 4 different tires. Finds which he likes that day, and buys a couple more for the day. Track has sales of 6+ pairs.
Now, isn't the profit from 6+ greater than the profit from 3?
Of course the manufacturers don't want them...It's prior restraint of trade and they can lawyer up and get it overthrown. It's happened before in this hobby business, so don't tell me it can't happen.
Foamy:
Have Hershman explain the math to you...
You need to do more research on 'restraint of trade' laws...
The use of spec tires, engines and other components is done all the time in in 1:1 racing...
At my own track I have a spec tire rule in our 410 sprint car division. One supplier... one compound. Saves the racers tons of money. And, OMG, they have to adapt to changing track conditions using the same tire all evening.
Several racing groups require the use of only the GM 604 crate engines.
How many companies supply tires for the NASCAR Cup series? NASCAR supplies spec shocks to teams on the super speedways etc.
The right for tracks and and organizations to set their own rules and standards has been challenged often in the courts. Unsuccessfully, I might add.
Go ahead and lawyer up ... you'll lose.
And, perhaps a little closer to home: Why aren't companies filing lawsuits now against the various retro organizations who mandate 'spec' motors and components for certain classes?
