Chassis stiffening through foam injection

[NoHachi]

Hiya,

We've all heard of the cheap way of stiffening a chassis through foam injection into boxsections of the unibody. Moto's car springs to mind. Sounds like a great solution for a street car where you don't want to have a rollcage threatening your coconut in a crash (rollcage without a helmet = coconut + steel basebal bat)
Have no experience on this matter, but have been interested in it for quite a while. Found some links that make for interesting reading. With all the new guys popping up on the forum, I hope that maybe some people will share any experiences that they might have.
