Being Uni-Body, if you plan on making some serious power and doing some serious launching, then yes, SFC's will be mandatory.
With that much power unless you have a bumper to bumper full boxed rail or hydro-formed set of frame rails, then you will need something to tie them together.
And Devil is correct, I can count probably more LS1 F-Body's running 10's and even quicker than I have fingers and toes to count them on here in Chicago.
