Looking to stiffen up my crusty ride. Which SFC's tie the most points together?
Thinking about the Detroit Speed ones as they look the beefiest.

Detroit Speed hands down, but it's quite invasive and you better have metal fab skills.

The UMI's are pretty solid and non invasive, however if you have a aftermarket/larger exhaust there will be slight modifications to get them installed but that's the case with most out there it seems.

Re: Which subframe connectors have the most contact area?
I didn't think it was a big deal really. I only had a problem in one area on my car where the sheet metal was a little thin from some rust. I kept blowing holes in about a 1.5" section
The instructions are REALLY good, plus they have installation videos. You're really only cutting a long thin rectang out of the car on each side, drivers side moreso than the passenger.

The Mopar guys have been installing through-the-floor braces like that in their uni-body cars for a long time. Makes for a very solid connection.

Re: Which subframe connectors have the most contact area?
I have the S&W setup under my car, mine was put in about 9 years ago. They used to offer two "out-rigger" bars that spanned out about 10" off of each main bar, and these bars tied/bolted directly to the side-rocker panel under our cars. for sure they are on my car but I don't see them in that S&W website photo.

yup, thats it, thats hte one I have. the outriggers are a nice easy place to put the floorjack and jack the whole side of the car up at one time. teh exhaust routing for my 3" exhaust is tight, but it works. car is solid. getting a 6 point S&W roll bar installed too this winter and S&W is top notch stuff.
