I agree in getting as much caster as possible, and any amount gained is better than nothing gained at all. For this platform, you can only gain so much over stock through camber plates alone. My argument is you should try to get as much caster as you can, but don't fret if you can't squeeze out every bit of caster angle as possible.

I was once interested in switching my GC plates for another set of camber plates that got more caster, so I did some calculations on a change from 6 to 7 degrees of caster.

After you take into consideration how much camber is lost through kingpin inclination angle and included angle (I used 13.5 degrees for included angle), the net gain in camber at 90 degrees of steering input was only ~0.11 degrees more camber.

At 180 degrees of steering input, you get closer to ~0.24 degrees more camber, which would be seen in sharper turnaround elements. This amount would then be fairly useful.

I would argue the average steering input angle is no more than 120 degrees in autocross, at which you would get no more than ~0.16 degrees.
