[7 2nd nova]

Is there an NHRA speed requirement for running a rear wing, on a door car? Or would it be a good idea to run one anyway if there isn't? I will be running a 31x16.5 Et Street, in a 66 Nova, at around 170mph.

Never heard of rule, but at 170, pretty much a given.

would it be silly to run one on a 150-160 mph true 10.5 car? I realize 150 ish isn't screaming fast but a wing might make it stable right?

My chassis guy told me he'd recommend one above 150.

Depending on body style, I've heard & read that the air wrapping around can cause an issue at 140-150.
