You technically don't require cast/camber plates. You can usually get back to a decent alignment with just aftermarket camber bolts. However, caster/camber plates will make your and your alignment shop's lives MUCH easier. As for the panhard rod, that depends on what panhard you currently have and how you have it setup. Your best bet would be to give us a call directly at 623-434-5277 so we can get more specific about what you have going on.
