That would be me
This is my first Mopar, so I've got alot to learn about whats out there and what works etc.
I do know that ladder bars wont work well if you want handling on the street
So far I havent found much as far as good "kits" for the rear suspension in the e-body. I've been in contact with Mark at Lateral Dynamics which is working on a Mopar project. They're planning on developing some suspension stuff for the front and rear for the Mopar, but nothing yet. Its still a work in progress from my understanding.
As far as front suspension.... ALterKations and Magnum Force are the ones I'm aware of at this point.
Once again, I'm very early in on this project and the mopar world in general, so I'm not much help right now.
I'd love to be in contact with you and we can bounce ideas off each other and share what we learn as the projects progress.
