Remind me about caster... I thought you wanted as much as possible positive caster (while still reaching the camber setting you want) in order to maximize camber gain (or minimize camber loss) while turning. This is at the expense of steering effort, which doesn't matter much with power steering.

Am I thinking of something backwards or are you getting too much camber gain?

too much castor.. which slows down the steering speed rate. Which is a bad quality in the Dodges. Some is good.. too much is bad.
Also.. too much castor raises the front ride height which effects the rear spring and roll rate.

now.. if it was just a track car.. Id leave it around 8.5 - 9 degrees,simply because it slows down the inputs to the steering.
