Just doing what I do
One of the best ways to keep heat out of the floor is to install heat shields under the car between the exhaust and the floorboards. It works waaaay better than installing it on the inside since it keeps all the interior metal from heating up in the first place and conducting heat through the edges all around.Is yours on the road already?? Just curious what you think about it?? I've got it saved to my cart.. How many did you use? Thats a 6x6' area so I would think I would need about 2 for the floor/firewall.
The Modern Mopar guys use it a lot when doing header and exhaust mods to keep the heat out of the cabin.
