Foaming the chassis

[Mystik]

ok, i remeber reading about foaming the chassis of a car to make it stiffer in SCC a while back. Now, im wondering.. should i do this to my dsm? would it be worth it? i plan on Atuo-X and maybe dabbleing in rallycross and road racing.. where would i put the stuff in? how much does it cost? any downsides? thx

i have heard from a friend and magazines articles that claim it does work, but i really dont know. some JTCC team use them, but, i wont try anything new like a FOAM until its fully approved and no downside for my car been reported
