I see quite a few cars with Petty-ish style bars running forward at a diagonal. Does this stiffen the chassis substantially besides the obvious safety benefit (or hindrance if you need to get out of the other side?)?

Trust me Dude, this is not for arguement.
Open the doors on a Miata without a roof. Measure between the door opening at upper most you can. Now jack the car up on both sides mid door opening. Take the same measurement again. Next do the same to a caged car. Please report results. If I had a Miata without a cage I'd do it.
Dave Wheeler do you have an uncaged car?

I chose to go with no Petty bar for a different safety reason. I thought it would hinder a quick exit out the passenger window if that type of exit would be needed. I know that fires are rare in our class, but that's the one thing that frightens me.

I've got a sleeved removable petty bar in my car. I thought I'd be using it for HPDE with two seats, thus the need for a removable bar. That idea has since been thrown out the window, so the bar stays put in the car now.
