I attended the GT drivers "lunch with the Comp Board" session at the Runoffs and recall that the majority of drivers/owners attending were in favor of allowing F.I. in GT-2 thru GT-5 (NOT in GT-1). I don't recall having seen anything else since then, nor have I seen any updates from the "GT Summit Conference".
I'd definitely let the Comp Board (and Dennis Dean) know your opinions - they want and appreciate your feedback.
