Any benefit to running both? Going to start on my cage in a week or so.. just trying to get some input. Basically wondering if SFC will help even with a well designed cage.
In that case I'd opt for the cheaper bottom-mount subframe connectors, welded in. These are legal for CMC (pretty sure they are, but check the rules -- I haven't read them for a couple of years.) If you cut the floor for subframe connectors, the tub will NOT be legal for CMC.I dont plan to now but I am building the cage so if I ever wanted to I could. 1 3/4 .120 DOM and nascar style door bars etc building it to nasa specs. The main thing I am wondering is if they are needed after a full cage. Ive done some cage stuff before but it was all off road racing stuff never anything like this.

IMHO, once you get a cage in the car, the difference between through-the-floor subframe connectors and external connectors is a bit academic. they'll still contribute to the longitudinal stiffness of the car, but their benefit is somewhat duplicated by a good cage, so don't stress about it too much.lol.
I have decided just to do the standard sub frame connectors. Going to start the cage in a few weeks currently doing one on my friends blazer.
Interesting. Any pics of the setup?[snip]
One secret Bruce Griggs and I talked about some years ago was using BOTH kinds of subframe connectors. Using two (in-floor and traditional,) forms a box-structure and has the same effective strength as a beam approx 6" wide. Very, VERY stiff. This is the setup I now run.
