I just finished installing the TVS kit on my Challenger. Still in the process of aligning the front end so I have not driven it yet. Install was pretty easy just ran into a couple issues. Drivers side inner tie rod hit the torsion bar since the Hotchkis rod ends are a little taller.
Alignment can be a pain if you have to re-adjust the rod ends on the UCAs.
Since the front end was apart I also replaced the LCA bushings with poly and welded AndyF's LCA plates.

I actually wish the car sat lower than it does but no biggie. It is a nice kit...fit and finish is really high quality. Hopefully it will handle like everyone says.
