Re: .370 and .470 GONE
I don't run SG, but I think that's the class that will tighten up most from this change.
Regan, I'm surprised with your power that you had struggles on the tree. My car is 3600# with 28" fronts and a 3400 launch RPM, with .040+ in the box. But I do have radial slicks that are probably helpful.
