are bolt in sub frame connectors good
- Thread starter murphmaster5
- Start date
They do not work as well as the weld-in connectors. Getting them welded is more than worth the time/money.

No they are not. The chassis will still flex with them. Welds are much stronger. The new edge convertibles and special addition Mustangs came with bolt-in subframe connectors, but they need to be welded to be more effective.

I've been reading the same reply for 5 yrs now...WELDED is the only way.
Does anyone really have any hard core fact, or is it all hear say from what everyone has read before?
Just curious, because I'm looking for some facts so when I tell someone that the only way subs really do there job is to have them welded ,that way I can back up what I'm saying with facts.

From my basic understanding, welds are stronger than bolts. When the chassis is flexing under load, the bolts will move (even if only slightly). Over time, this can begin to destroy the holes drilled for the bolts. It's just like how the control arm mounting areas will wear out over time if the car is abused and does not have torque box reinforcements. When the subframe connectors are welded in, you eliminate this weakness.

5.0 Nostalgia that is exactly my understanding and I AGREE ... I was hoping that someone had a graph or chart that actually showed the difference.
I've read what MM says about bolt on versus welding but again not what I'd call hard core evidence showing the difference and that is what I’m looking for.

Comp Engineering makes my fav sub frame conectors.
you can weld in the bolt in ones, but the hot ticket is to put the weld in ones. The go through the floor and use the sear streagh of the floor to stiffen the car. They are a lot more work, but worth it

You can prove it to yourself quite easily. Take some u bolts and lie them on a table just like your subframes would be in the stang. Now get some channel aluminum and set the ubolt ends into the channels on both ends, just like subframe connectors(kinda). Now clamp channels together with some welding clamps and torque the whole assembly. Retry without the clamps and in place weld them.
I just realised thats really not that easy lol
You could take 2 pieces of ange iron and bolt those things together stacked on top of each other, then put one end in a vice and pound on the other end with a hammer
. Watch what will happen to the bolt hole, same thing is happening when you drive around with bolt in subframes.
