I built some adjustable strut rods

I opened this post a while back looked it over and then closed it. I opened it back up tonight wanting to see what the "naysayers" might be mentioning about this mod.
Well funny thing is, I kind of agree with the naysayers. The design WILL cause the LCA to twist more than stock, because the strut will no longer add torsional stability to prevent the LCA from twisting, furthermore this is going to be made worse because the bolt on mount raises the mount point as to put more leverage into the twist that the strut will induce.
In short, the stock design lends support to the LCA, this design will also induce twist.
I think the basic idea is good, the workmanship is great, but the fundamental change in structure is a little too scary for me to take the risk without updating the LCA.
The question is whether this induced twist is beyond the functional limits of the LCA.

I think the system would be a good improvement to your suspension if you hard bolted to the LCA and used your heim joint at the front mount. It would add rigidity.
When the LCA/Strut bar assembly fails, it does not go quietly. It will fail during speed or hard braking if it has a point or component that is weak for some reason.
I broke a Strut Bar on a '65 years ago at around 100mph. The frame hit the pavement, the wheel assembly wedged between the pavement & frame. The end result was that the car rolled several times, it was painful, I do not recommend it.
You have gotten some good honest responses here. Consider it one mistake that you DIDN'T have to make yourself.
By the way, that is some beautiful welding!

I can go measure them tomorrow if you would like. However most on this forum seem to think that this setup is dangerous so you should take that into consideration. I however believe it to be fine as I have easily put over 1500 miles on it in the last year. The car stops better than ever, handles fine, and rides great. I however would not advise putting it on anything that is going to be taking corners at extreme speed. My car is set up for drag racing and street driving. If you were going to autocross the car or something like that I would go with a different style so you could keep the swaybar.
