Austin Vert's Subframe Connector Question.
Hi to all,

I realise many threads have been posted about subframe connectors, but going through them, i could not see any discussion about ride characteristics per say.

Sorry if this has been discussed before, and i've missed it.

A lot of you guys with '71'73 Verts out there have sworn great things by installing connectors. I understand how it would make your vert a more rigid package, but my concern would be how the connectors would effect the RIDE of the car in terms of making the ride more 'HARDER' or 'FIRMER' than it would be without them installed.Would you feel the bumps a lot more if you had them on for example?

I've pretty much tuned my front and rear suspension to what i wanted it to be, and i would not want the ride to be any harder than it is now.(stock front setup and five leaf spring setup for the rear, with no rear swaybar and standard gas shocks).

If anyone can put me in the picture on this question, i would be most thankfull.



Well... in the near future, I'll be able to give you my experience on before and after. Sometime in the next few months, I'm going to take my car to a frame shop and have them check the frame and weld in my Global West subframe connectors that arrived from Jegs yesterday.

My car is pretty loose right now, so my experience my be different that for you if you were install.
My car isn't a vert, but my suspension set up is just like yours. I don't feel like my ride got harsher, just that the car's responses were crisper.

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!
I've never actually driven mine (a jaunt through the parking lot doesn't count - even though it's a huge step in my case rofl ), but my understanding is that it will not stiffen up your suspension, per se. They will, however, stiffen the chassis itself, which in-turn eliminates body flex, which is somewhat unrealized and often tuned out with suspension kits (even though it remains with the suspension doing its best to compensate for it).

Our uni-body cars tend to flex a lot more than we can imagine or feel ('verts even more, I'm sure), and the subframe connectors will essentially complete the 'frame' under the car, for greater structural rigidity, which could make your suspension seem to tighten up somewhat. But I would think that feeling would be more limited to turning the car while in-motion.

Just my take, and 'uninformed' at that. When I actually do start driving mine, it'll already have the Global West subframe connectors installed, so I won't have a benchmark to compare.

Hope that helps!

I don't really notice body flex, so it will be interesting to see if I feel a difference once they are installed.

The bigger issue for me is being sure my frame is straight, and tightening things up. I'm getting some door sag, and I don't know if it's frame related or just a bad re-hang when the PO did the restoration.
Minor door sag, or misalignment may be due to worn hinge pins. You might look into new pins and bushings. Most of our cars need them!
Yeah, that may be all it is, but if I'm going to install subframe connectors, I may as well be sure the frame is true first!

Let me know what you find out about your frame after you have it checked please.
After I installed mine on my mach 1 it was a night and day difference in handling and the feeling of the car...... for the better! my car seemed to wonder when driving before and you were constantly making corrections to the wheel. I never really noticed this until after I put the subframe connectors on. it seemed to tighten everything up with the whole feel of the car. Much more responsive to the steering wheel and didn't seem to wonder nearly as much. And all my front end parts we replaced about a year before I installed the subframe connectors. Also when I launch the car hard it seems to stay a lot straighter. Just squats and goes now....if I can keep it from smoking the tires! You won't be disappointed by adding them. I think all our 71-73's regardless of body style would benefit from them.

I installed a set on my fox body. They didn't change the ride. But they sure did tighten the car up as a hole.
