Yes, that's correct.
CASTER is the "lean back" of the imaginary top to bottom steering axis, similar to a motorcycle.
Positive Caster gives self centering steering. No steering rake would give no trail, and although the steering would be quick, it would awful to drive.
SAI also needs to be taken into account.
Street cars can run 3 - 7 positive caster. I like 4, and up to 1 degree negative camber front and rear.
High positive caster is good for stability at high speed with less effort from the driver. To much caster will lower grip on high G cornering, so about 2 degrees on a race setup.
