Default Truth about SFC's / STB's

Everybody has heard the hype about these two items. And I know from the comercial what they do (tie the subs or towers together). But what is the practical application? Do you stay more level around turns, do you pull more G's on the skid pad? Dunno.....

Just got some subframe connectors a few weeks ago. I wish I had did this when I first got the car. The car feels much tighter, and is less prone to squeaks and rattles.

I have 4 sets of railroad tracks that I cross on my way to work everyday. I can definately tell you that my car feels much more solid, than it had been without the subframe connectors.

Just my 2 cents

I have got first the SFC's and then 4 weeks later the STB. I can tell you that the SFC's are worth the money and that the car feels much better even on high speeds. One of the best mods you can do to your f-body.

By having the STB installed I have much more tire contact and the car handles much stable in the curves. If you can afford buy both of them if not take the SFC's as you got more for the money compared to the STB.

Hope this helps.

Any suspension tuning (e.g. springs, shocks, swaybars, etc) that you do is only as good as the foundation to which its attached. Excessive chassis flex then, will directly impact your suspension tuning. To make matters worse its a generally unpredictable and inconsistent impact. So it benefits us to make the chassis as rigid as is feasible. SFC's and to a certain extent a STB will help do this.

Wow, good deal. When installing them, does the suspension have to be loaded, or does it matter? Thanks for all the input.

SFC made a huge difference
STB... well, it looks nice

But let me add, a heavier set of sway bars does wonders, and it is inexpensive and easy to install....

I think you mean larger (you can get hollow bars).

Did you do the sway bars before or after your SFC's? Will it be as drastic a difference after? Thanks for the tip, I'll check em out. Any suggestions on it, or are they all about the same?

my first supsension mod will be SFC's, then swaybars. the STB will find its way on eventually when i have some extra cash. thats generally the order of events i have been advised to take.

You will notice drastic differences with both mods, they'll just feel different...

The SFC's will help reduce body flex...In the turns, your outside tires will stay planted better, due to the body not flexing as bad as factory. Want to see your body flex? Jack up either side of the front end, without the SFC's, the front corner that you are lifting, the tire will leave the ground for quite a few inches, and your other three tires will still be on the ground!!!

With SFC's installed, do the same thing, and this time the front corner AND the same side rear corner will lift up as well.

Swaybars, especially a beefier front swaybar, minimum 32mm, you will notice MUCH less body roll when you are in a turn, you will feel it as well as see it...

Hope this helps.

I installed my sub frame connectors at around 10k miles. My car now has approximately 40k miles and my car is as rock solid today as it was when I put them on some 30k miles ago. It is actually more solid than when it rolled of the showroom floor.

My t-tops still fit the same today as they did when I bought the car, I don't get the 'mystery' rattles that a lot of other f-bodies have.

Definitely get SFC's installed ASAP, especially if you put sticky tires on the car and launch hard, that will torque a frame quicker than anything.

I also noticed a big difference when I did the SFCs, One question I have been trying to get an answer to though is does a STB actually hurt quarter mile performance? I know it helps in the turns and I can feel the improvement myself but some have said that the STB will slow you in 1/4. Any truth to this?

I have a 2000 TA, and just put 51K on the odometer. I've just recently put 18" C5's with 265/40/18s on them. I am just about to spend some money on springs/shocks to help improve the ride and lower it some. I am starting to get irritated with the growing "phantom noises" and creaks, and with the 18"s it just makes it worse, the handling is like a train, I can feel every pebble on the road. Would it be better for me to get SFC's welded in first, or springs/shocks to help alleviate this problem. I want to get rid of the squeaking, and make the ride a little smoother.
