Man what did I say about this kit????

Didn't notice the tubing used for the frame connector is bent. Also didn't realize the plate for your roll cage is not part of the connector.

Here is something to think about. A straight peice of alluminum tubing. You can walk around and push ceiling tiles out of position and even slide boxes off the top shelf with it. Now take it and put the slightest bend in the tubing. Go back and try to do the things you tried before. You can't the bend just get's worse.

Tubing is bent all the time in race cars. But, if you notice there is a supporting structure welded in to support that bend.




Omg dude you totally called it

Yes, let's look at your analogy. Pushing ceiling tiles out of position takes almost no effort. Your piece of aluminum tubing with a slight bend in it is going to need to be paper thin for it to bend oppose to moving a ceiling tile. Assuming you're not using a paper thin aluminum pipe, the pipe even with a large bend in it will be much stronger than the force it takes to move the ceiling tile. This is exactely why your anology doesn't work. A 1.625 .120 wall pipe with a slight bend in it is a lot stronger than the sheet metal it's bolted to. The 1.625 .120 pipe will be the last thing to fail.




Nobody is talking abgout failure, we are talking good design practices, common thinking is any member that changes direction needs to be supported/braced/triangulated at the bend. If not, bending will be significantly easier, however slight. We should always be trying to achieve the greatest stiffness with the least/lightest design, anything else is a compromise. KISS Memo applies here I think,

His analogy was only a generalization for visualization purposes, wasn't likely meant to prove or disprove anything.

Keep in mind that when we are building these nice desireable cars, fasion goes right along with function. With the location of the spring hanger mount, floor and front subframe, there is only so much you can do while keeping it from being ugly. Could it have been done with a straight tube and not cutting the floor? Sure, but it would be ugly with extensive bracketry to get it out of the way of the floor, while making it hang down and be terribly visible. There is always a compromise. The compromise on these subframe connectors is a slight bend while keeping it simple, clean, easy to install and way more than strong enough.

The only reason for an analogy is to try to prove or disprove something. That is the definition of an analogy. It is a shame that people work really hard to develop new products to improve our classic Mopars, especially a product to protect from damaging them in a race environment and they get scrutinized. Is it like this in the Ford and GM world?

Maybe we should change the rules that "scrutiny" is no longer allowed on Moparts.

And if allowed, I don't agree with your defintion of "analogy" in this threads context. Ask the writer what his intention was.

Pointing out and discussing design compromises on hardware is not a new thing in the automotive world.

Funny thing is while we are so OT, the "bend" fix is kinda easy.

There is no "bend fix". The pipe is bent so it doesn't have to go though the floor of the car. To have a bolt in frame connector that bolts to the factory spring hanger mount it is physically impossible not to have a bend in the pipe, and these have been designed to be as straight as possible. To claim there is a "fix" and it's "easy" is laughable

What kind of money does this kit run. I checked the website and couldn't find any info on it.

We haven't actually released them to the public yet. They were installed on Keith's car for test fitting, etc. I believe they decided on $429. They will be released on on our website in probably a week

For $429 they better be powder coated also...

$429 for sub-frame connectors and the drive shaft hoop kit. No they are not powder coated.

I have to admit, I chuckled a little bit when I read that, you obviously don't get it. I bet the next guy that knocks off this design will. Keep laughing.

Jack, can these be plated like the rear suspension kits?

One important point to all of this that the system is bolted in. This can be done by most any car guy lying on his back under the car with really basic tools. Not everybody has a hoist.





Double sided tape would be even easier. The nice thing about bolt in bars is the owner can do all the fitting and prep work so that the car can be driven to the welders to get the install properly finished.

Downside of the bolt in bars other than not being as strong, is if they require drilling is its harder to fill holes than grind down welds when you want to go back to stock.

Nice looking parts but I do think they need to be welded. One other think I would consider too is adding a gusset or a small bar to triangulate the main bar to the bracket that wraps around the T-bar Xmember.

To claim there is a "fix" and it's "easy" is laughable

The long tube (judging entirely from the appearance as pictured) has the OD of at least one end located outside the OD of the bend (in cross-section, the diameters don't even touch).
With the same bend, the resistance to buckling in compression can be substantially increased by simply increasing the tube diameter so that center of one is inside the diameter of the other.
