Jeff, from what I have seen, the SIR pretty much killed the ITS version as I never see one run in SEDIV.

Going to ITR is certainly a choice, but the tire budget gets doubled!! If I build one I would prefer to stay on the 15 X 7 wheels.

Any thoughts to how the CRB could be prompted into revisiting the SIR?

And finally, the unrestricted BWS's times have been eclipsed most everywhere, which leads me to believe it was not actually an overdog, but several extremely prepared cars in fields of not so prepared cars.
