Default Alignment on stock suspension - caster too low?

I got an alignment today and had them max the front camber and caster. I was able to get 1.9 degrees camber from the front but the caster only maxed at 5.1 degrees. Is this normal when running this much camber in the front? Is this too low? If I backed the front camber down to maybe 1.6 or 1.7 degrees would I be able to get much more caster out of it?

Here's the complete printout:

its a little low, might indicate a torn compliance bushing.
my ap1 with fresh compliance bushing and stock suspension only gets like 5.5-6 castor with front camber joints i get about -2.5 camber.

I got about the same yesterday out of mine. Just put my04 back to stock and it feels super slow as far as steering feel now

Static caster will be more limited as you increase camber. On my AP2 I did -1.6 front camber and maxed out right at 6.0 caster. One nice thing about camber joints is being able to increase negative camber but maintain 6-7 caster.

You will definitely lose a bit of steering feel compared to 6 caster, but you will definitely make better use of the front tires with -1.9 camber. So you have to decide between overall front grip and steering feel. If you want both you can get camber joints.

Good thing I am running this way for only a month or so.
I need more camber and caster!

I haven't really tested it out much yet but the turn-in seems to feel pretty good so far. Driving on the freeway seemed to have a bit more "wandering" with bumps and grooves on the road though.

I believe caster only changes how fast the steering wheel returns to center,...but i may be wrong. Thats what I was implying though

From what I've read it has to with the steering feel overall. Sort of like a shopping cart - lots of negative caster: easy to steer but not so good for high speed runs. Or a chopper bike with a ridiculously long fork - lots of positive caster: stable at high speeds but a bitch to steer.

Caster changes your camber gain with steering angle, it makes a big difference to the handling of the car, not just steering feel.

^This. You can run lower camber which benefits fast sweeping turns (low steering angle) but caster adds camber in tight corners (more steering angle). I like big caster. I've tried lower caster and it just doesn't work with my driving style.
