Nope, once you go with one of those frame/chassis setups, you are looking at GM stuff.

Hotchkis makes OEM-style replacement stuff for Mopars - torsion bars and strut rods and swaybars that replace factory stuff, but are better.

I doubt that any of their stuff would be compatible with the GM parts used on those setups, but I suppose you could ask.

I don't know why you would, though, those are three very reputable names in the AutoX/Pro-Touring world, I'm sure whatever they sold to you will be great for handling, even if it will be super expensive.

My personal problem with all of that is: How much greater would it be than the Hotchkis or Firm Feel stock-style stuff attached in a factory way for a lot less money?
