This is a very interesting thread. I am questioning putting a cage in my car for several reasons and this just added to it. My problem is that I plan on running maybe a low 11 high 10 in the 1/4 so I believe I need one if I want to be able to go to the track and not be kicked out. Ahhh the dilemmas of life.
Here is a thought for the people who just want the structural rigidity and do'nt necessarily need the cage. syborg tt was talking about his truck where they used liquid steel to fill in voids to make it more rigid and it reminded me of a article I read where racers in japan were using a two part spray foam insulation and putting in cavities in their cars to stiffen the chassis. Maybe this would solve some of the problems by just using the spray foam like the liquid steel.
This is an industrial spray foam and is like a two part that is mixed when it is sprayed not the stuff you buy in a can at Wal-Mart.
