JB...Everything you said is correct....depending on what you want to do and type of race car....in my case...0 toe, 0 camber, 13 degrees caster, I want to go in a straight line. Normally 13 degrees would make it difficult to steer but hopefully we don't do to much of that. Another factor to take in consideration is "scrub radius" which if you get that down to 0" the steering is quite neutral...does away with the flip flop effect of the 13 degrees. btw I use a steering rack with heim ends to take out all of the slack in the steering.
