I've been doing some reading in the suspension/braking section, and have come to learn that SFCs don't do as much as I had originally thought. They will keep the frame more rigid, but rigidity shouldn't be an issue unless you are doing radical things (and 400 hp isn't radical) or unless the car has been wrecked before. Not to say they are a bad mod, just not an absolute necessity.
That said, I'm running the UMI 3-point tubular SFCs, and have no issue at all. If I had it to do over again, I would have spent the money elsewhere first, such as LCAs, adjustable panhard, etc.

SFC's are a good mod, and 400rwhp you will get flex. If you have stock hp and maybe want to autocross then that is the only reason you might not want them. If you ever plan to hook, and more so with 400rwhp get them.
The tubular ones are fine, I have them and I push 551rwhp.
Peace,

3pt vs. 2pt. SFCs
This is kind of an old thread, but it shows you where I'm basing my response from. The SFCs are a great mod if you are running stock suspension, but not necessary if you upgrade to a better suspension.

Sub frame connectors are great for even stock power. They make your car pick up more evenly. I put them on after I did lid,cat back, and rear control arms. I have BMR boxed and welded ones that I got from Speed Inc. I love them. Makes a huge handling difference on the car.

i put my boxed SFC on the car at 45K miles when i got the car. i felt an IMMEDIATE difference over uneven roads...particularly on bridges (i live near LOTS of them).
the small "dips" formed from each section of the bridge created a pretty good test area.
i could feel the car's suspension working more, the body was flexing less and absorbing less.
to me it almost seemed liek the ride got rougher....since the body wasn't absorbing as much, the shortcomings of a 45K mile stock suspension really shined through.
i say they are a GREAT mod. and i'm not convinced you'll ever notice a difference between the different kinds.
supposedly the boxed version hang lower, but on my car they were not the lowest part.
i have quite a few install pics on page 3 of my website in the signature

I'll support my point no more. I'm not saying they are a bad mod at all, but if I had to do it all over again, I'd go with suspension mods before I'd get SFCs.
SFCs won't eliminate flex either. They help eliminate it, but no car is 100% rigid. This is per Steve Strano, whom I tend to believe when it comes to suspension/chasis issues on these cars.

Yah I agree. No car is 100% but you can get pretty close. I also have a BMR strut tower brace wich also helps out a bit.
From what I've read on here, the 4th gens. are alot more rigid than they used to be. But back in the day it was a rule of thumb that if you were pushing 300+ rwhp and dumping the clutch in ANY unibody you NEED sfcs. Failure to use them resulted in a buckled floorpan under the back seat.
Just a little food for thought.

the ability to jack your car up from anywhere along the side is awesome. i cringe when i see or hear the door/doors twist. they are worth every penny.
