The man wants MORE caster. How about this idea?

Instead of starting a new thread, how about THIS question......
How much is TOO much caster for a classic car with power steering?
I'm working on my Charger and at one point, I'm at 8 1/2 degrees positive caster with 1 1/8 degree of negative camber.
It seems that the car would be hard to steer even with power steering.
