did a search but did find anything. Planing to foam my new 83 GTI project, did this before in my 98 2.5rs and my old S13 240SX, short of installing a cage its the best mod for stiffening your chasis, made a HUGE difference.
Anyhow, planing to run 8lb tpf in the rails and 2lb in the pillars again, wanted to see if anyone else had any experience and how much tpf they used all together and any other good spots to hit while I have the carpet out. If anyone is interested I'll add a write up with pics when Im finished as well. thanks!
