It's called a firewall because it's supposed to protects the occupants in case of an engine compartment fire. Wood is NOT an option. Steel
is favourite IMHO.
Tell them about the bent treacle edges!

Steel is the kiddy! Fully welded, not just spotted increases the tortional ridgity of the chassis as well as protecting you.
Nailing and glueing some ali or wood is a bit futile imho.

because in the time it takes to burn through, you'll be out anyway... and if you're somehow stuck in the car, you're probably lelled
anyway.

Yup. My mk's got a fibreglass scuttle/firewall and bonnet. In fact all the bodywork is fibreglass.

Isn't the steel / ali around the footwell part of the firewall?

Sorry shouldve said external bodywork. Yes the interior panels are steel/ally, but it's open where the steering shaft goes through the
driver's footwell panel. And since the battery tray/scuttle is fibreglass it doesn't make any difference to the fireproof-ness.

There is NO SVA regulation re firewall matereial.
If youre gonna race it then thats a whole new ball game.
Experience is what you get when you don't get what you want!!!
