Rear Firewall Question

EVERY hole needs covered, defroster holes, all the small holes that are in seemingly random places. That’s why they want a full sheet.

And the rear seat area needs covered or it can catch fire and let fire inside the car.

Read the rule book as to the fire resistant caulk.

Of course this depends on your tracks tech people. Some tracks don’t do much, but it’s for your safety.
