I wish I had added some on the flooring but, the only real heat is coming from the tranny. Next time I have the transmission out, I'll fab up a two piece aluminum heat panel, sandwiching heat mat between them, and on the tunnel.
I wish someone like Consumer Reports had a test with several heat barrier company's. I have heard good reports from this company.

Have any of you seen a comparison test between materials and manufactures ?
