I have been doing research on subframe connectors and just wanted to know the differences between boxed weld in subframe connectors vs. 3 point.
It semms that the 3-point will work better at strenghting my chasis and adding stablilty compared to the boxed.
Only thing I dont like about the 3 point sfc is that they're more expensive than the boxed style ones and appear to be more heavier, can anyone shed any light on this?
is there a big difference between boxed and 3 point?

Any 3 point will be stronger than a 2 point imo. I went with the tubular ones from UMI because I didn't want to be able to see them from the side of the car.
I hear the boxed and 3 point hang a little lower.

All you need is something to connect he front/rear unitized frame rails. This devides the load between the two that would otherwise be absorbed through the weak floor pan. Just like the rear pan hard mount brace that some people remove. It ties the two rails together and devides the side loading between the two.
IMO the three point is a waist of money unless your looking to add weight. The standard two point is more than enough for even the most serious racers. Even then a lot of the two point SFC's are heavier than needed to do the job.

i have 3 points and a tunnel brace. they oil join in the middle and they distribute the load more evenly according to umi. either way they are both awesome pieces of work.

I voted Boxed. I have had Kenny Brown DD SFC's before and I really, really liked them. I have been wanting to try the 2pt. version. I think I'll go with UMI's bars.

Well guys I just installed a set of the black bolt-in UMI 3pt SFCs.
They are really nice pieces... They are works of art.
The truth is I cannot feel any difference.
If I was to do it again I would go with 2pt SFC to save some weight.
Never the less I don't regret installing them.
Maybe I would've felt more of a difference if I had gone with
red instead of black. lol

But my main concern is the price difference and extra weight, is it worth it?

I have been re-thinking the whole thing and have decided to go with the UMI 3pt. Only reason being i have a tunnel mount T/A and would like a lil piece of mind, in knowing that my T/A will not rip the bolts outta the floor. LOL.

That picture shows our tunnel mounted torque arm installed with our 3-Point SFC's. This is what we consider a "Ultimate" set-up and we have vehicles running single digits on this set-up. The torque arm bolts under the SFC's and allows the pressure to be distributed through out the SFC's and not the floor of the vehicle.
Anyone of these torque arms are the same as the picture, the only difference is the exhaust and drive shaft loop options-

The SFC's shown in the picture can be seen here and our available as a weld in version or bolt on version-
