Sub frame connectors are not needed, I went 9.4's without a cage, no measurable body flex. Gone 8.6's with just a 8.5 cage, no connectors. If someone can find a photo of a hellcat twisting the unibody from a dig, please post it, I have thrown 1,150 wheel HP at it, it does not twist.

I went with the matrix connectors from Pettys garage. They are bolt on.
I've never installed the weld in ones I bought. The bolt in style looks a sensible idea. I fitted the Speedlogix front strut brace and that was a ballache as my tech had to drop the struts out of the turrets as it would not fit over the canted bolts. The Pettys rear brace worked fine.

ditto, no flex. Dodge did an excellent job and anybody with Subframe connectors just wasted their money. Check out the drag cars, they lift straight up & both wheels are even.

If you look at the factory Demon video announcing the 9.65 second street machine with both front tires off the ground by an inch or two, you can see that the unibody is very rigid. It makes sense that the Hellcat Charger and Challenger body’s are designed to handle the HP and minimize flex in the body or there would be a lot of issues.
