I really like my UMI tubular SFC. Def made a different in handling. I've still got to weld them in. As far as the 3-points go I don't know much about them but if you have the extra money to spend on them I'd say go for it. The SFC for me were just something I said screw it and just put them on for the heck of it. Didn't really have any expectations or need for them. Good luck!

Hello
Thanks for the recommendation and glad you like our product! We offer a variety of sub frame connectors for the F Body! When if comes to tubular or boxed. Tubular is a little lighter in weight and a little cheaper in price. They will both handle anything that you can throw at them! We offer bolt on or weld on versions (boxed is weld on only). And we offer sub frame connectors for convertibles as well. All of our sub frame connectors allow you to tie your rear lower control arms into them. For added reinforcement. As far as the 3 point SFC's go think of it as a roll cage for under your vehicle and if you are running a tunnel mounted torque arm this is for sure the way to go! All of our SFC's tuck up well so you still will have good ground clearance and added stability. Below is a link to show you what we have to offer.

If you have any other questions feel free to ask and I will be glad to help!
Thanks
Brad

absolutely LOVED my SFC when they went in.

the car felt more solid.

i noticed it most on bridges.....i have ALOT of them here in the Fl keys. those small dips between the bridge sections, at highway speed you could feel a significant difference in how the car reacted.

in a way it made the car ride ROUGHER...but in actuality it was the that the frame was absorbing less of the flex...forcing the stock spring/shocks to do more of the work. and we all know how great decarbons are

front mount

rear mount

ground clearance view...i DO have the factory GFX though

Install looks great!! Thanks for being a BMR customer.

twelver12, go with the boxed. They are a stronger unit and as you can see from these pictures ground clearance is not an issue. If you have any questions please give me a call.

i've been nothing but satisfied with all my BMR stuff.

although my sway bars are losing their powdercoat....granted they've been on for 6yrs.


but i agree, the boxed are great. for a small amount more weight, and a slight drop in clearance (if you dont have the GFX) you get much more rigidity.

and they make a great place to jack on.


the 3 point are overkill i think. and most that i've seen have that 3rd connection on a pretty weak section of the underbody. so i can't imagine you gain much more over good boxed SFCs.

I could see it limiting cats, but that's about it.

Hello, Actually the 3-Point SFC's will not effect any exhaust system out there... they all clear with no issues.

Hope that helps!

Why do you think that? Most exhausts I know run down the trans tunnel just to the right and below the driveshaft. I've NEVER seen any sort of production exhaust interfere with a 3-point connector because there just isn't room to be running an exhaust between the floor and the ground where the SFC's sit.

If your exhaust runs inboard of the tunnel brace mounts, then the SFC's cannot interfere. Just look at how they bolt up:

I had sfc's on my old car and loved them. I went with BMR's boxed weld ins. Without the factory ground effects you can see them slightly(maybe 1/3inch worth) under the car when you stand back 15+feet from the side of the car. I will probably be going back to them when I get sfcs for my new car.

Our boxed subframes are a tried and true design

Let me know when you are ready for the 2nd pair on your next project....

for exhaust i was thinking true duals....but looking at that picture, i guess that would even clear.

i was thinking my TDs went outside of the mounting bracket for the 3rd point. but i was thinking of the trans crossmember.
my bad.

Running BMR tubular weld in. I would stick with weld in. Other than that, there is no bad choice.

thanks for all the replys guys i went with the bmr boxed weld ins from summit, ordered them thursday morning and got them friday afternoon on ground shipping man i love their service, also just got some umi lca's and a stb from them also gonna put them all in at once tuesday at school

~~~now anyone have any suggestion on preloading the sfc's? not sure if thats the right term or not but i have asked several instructors and others and it seems to be 50/50 whether to install them at ride height or support the car from the middle so the body flexes a bit and they have constant tension on them

ALWAYS weld them up with normal weight on all 4 tires.

otherwise you could be welding a twist in the frame.
