Aftermarket arms that achieve those rates of caster are typically combined with a lower control arm that moves the ball joint forward to keep the wheel centered.

It’s okay that your wheelbase is out of spec. Spec would be for a car with very little positive caster. And the difference side to side is within spec for what you’d see with a road crown alignment.

Now that the spacer has been removed do you have any contact?

No contact now without the spacer. That made a bigger difference than I thought it would. At it's worst, the tire get's about 1/8" clearance the fender bolt but no contact. With the spacer it was making contact with the fender.
