extra bracing for autocross
I already have MMFLSFC and the stock strut tower brace. I have a bunch of 6 foot 14 gauge (0.075" thick) square 1x2 inch tubing that i figured I could make use in some extra bracing. I know griggs has an upper subframe connector, so would welding a few inside the car where the uppers go help? how about a lower k-member support? maybe a rear shock tower brace (sounds ussless)...
Ideas?
I enjoy using my new welder if you cant tell, haha.

edit:
I found some, i may try this, put two of my tubes together to make a 2x2...

A quick update, I gutted the car and cut into the floor. I made a 2x2 beam by placing two 1x2 beams next to each other so it'll be stronger (~22%) then a equal thickness 2x2 beam. I made a few extra pieces for bracing to toward the bulkhead area. I have the drivers side all ready to weld up but the passenger side needs its cuts to be cleaned up still and bracings cut out . Ill get some pictures up tomorrow of my progress.
I cant wait to test it out, my goal is to have it be like jazzers car with the one jack stand

Those are not called upper sub frame connectors they are called threw the floor sub frame connectors. You use threw the floor in place of regular sub frame connectors. As for stiffening the chassis they really won't do much over regular SFCs and is only adding unneeded weight. You best option would have been to do a 6 point cage to tie both sides of the car together then tie in jacking rails to the cage.

The upper SFC's, as I call them and what he is as well, are SPECTACULAR for support and are indeed the reason why my car can be supported by a single jack-stand (pic in Garage). My car has exactly what the example pic above has and all but eliminates the racking or twisting that can happen under open track/AX conditions.
With that said, Ox is correct that a roll-bar would be even better, but more intrusive to the interior of the ride and why I opted not to go that route.
