Layer fiberglass on the back. Done.

^ what he said, But foam might not be a bad idea honestly if done properly never thought of that. Only down side is if u ever need to fix a crack on it, and there will eventually be a crack.

I use carbon fiber on my kit on the IS300. When I have time I'll lay the rest on my S13. Buy quality fiberglass, resin mix, etc......quality resin lasts a year or expires after. Make sure there is no air bubbles when laying the fibers. Air bubbles makes it weak and the structural integrity is weaken.
Don't buy from local auto stores. Low quality crap.
