Drivetrain G Force sub frame connectors

[limp]

I tried a search on here and found nothing about these..
Has anyone used or been around the G Force sub frame connectors sold by Southside Machine??
Are these relatively new or have they been around for a while?

These tubular sub-frame connectors were designed to tie the front and back frames together using the supplied bolt-on hardware.

#1 I don't see any seat frame connectors
#2 very few use bolt in style
Although they look good and could likely be welded.
Didn't compare wall thickness.

If you watch the video the manufacturer comments that the seat is a separate problem and is purposely not attached?? I can't answer this one as I have never installed ( yet) sub frames on a fox body.???
Yes, its a bolt in, but a very unique way of bolting in this system.. Actually tying in the front K member with the bolt the rear control arm swivels on.
Again, just wondering what the people on her with the experience of these cars think of these or if any have used them??

They leave a lot to be desired with regards to twist and rigidity. This is all due to how they attach to the reward k-member mount and forward of where the rear LCA attaches.

I’m not a fan of the rear attachment point with a high hp car as the torque boxes on these cars are suspect anyhow. I guess if you weld up the torque box ( you should do this regardless) then on a DD it would be okay.

Maximum Motorsport’s full length and Global West’s full length attach to two points on the front subframe, have seat brackets, and then attach to the rear subframe in the bulkhead area. This and they are weld in which is a far superior connection compared to bolting in this application.

I say all of this with how I would build a car which translates to I want the chassis as stiff as I can get it. For a DD or Garage queen the bolt in is an improvement and will definitely help.

I ran across a couple threads on the 99 and up cars having them. Search “south side machine subframe connectors”.

Looks like full length weld in MM connectors it will be then...

 

[AeroCoupe]

Better choice IMO. With them being welded in the car will have more torsional rigidity and they physically attach to the car at three points vs two with most.

I will say that if you want the car even more rigid install the Griggs Racing uppers as well. I have them in both my Foxes and the cars are freakishly stiff.

I will also say that when people say subframe connectors made the car ride better it’s the absolute truth.

Installing connectors

is a no brainer as my 83 is a convertible.... I didn't do this to my Dodge when I restored it and I regretted it... I wasn't going to mess up the perfect " underneath" of it later....

Sn95 convertibles come with bolt on subframe connectors, and they are a much stuffer chassis than a fox due to improvements in Manufactuing methods, but even the SN guys say that taking the bolt-ons off and putting MM full lenght in made a huge difference.

Pretty sure your dodge was a full frame to begin with.
Glad your getting full length ones, that's the first thing I did back in 07 when I got my Stang.

Jeesh I must have missed that when it was on the rotisserie for 8 years.....

Sorry, no. They are unitbody cars too.

No , shows what I know about mopars

When I was in the Mopar club, it was a big joke whenever someone advertised a " frame Off " restoration mopar for sale.... We knew it was probably a chevy person " flipper".....

 

[Mustang5L5]

I still heard "frame off" when it comes to restoring Fox bodies

I didn't know southside was still around. Their control arms are probably responsible for more torque box damage than any other company in existence.

And at $350, it would appear you get something worse for $150 more.
