a few corrections...Stock/ SuperStock are allowed to dial under their index...the index is the minimum et you have to run for the class.....breakout are in effect...unless you race a car in the same class as your is then it is a heads up no breakout race.
Indexes are adjusted only for the physical elevation of the track...not for atmospheric conditions.....and all index are adjusted...Stock..SuperSTock...Super Classes and Comp Eliminator
