Steeda camber plates - does caster change with camber?

[GTP]

I measured that the shock tower 3-bolt pattern is rotated about 18 degrees with the inboard/outboard line of travel for camber plates.
You can see that in the first photo below.

Steeda plates' have the camber line of travel aligned with the 3-hole pattern. I believe this indicates that there would be a very slight increase in caster with increase in negative camber, because the plates travels inboard AND rearward.

Can anyone confirm?

Bonus Question:
When the Steeda plate is positioned at the slots' center, does the bearing also center within the bolt circle of the 3-bolt pattern? Or, is there an offset of the bearing to the inboard direction? (Which means the plate will adjust farther to negative camber than it will to positive camber.)

Most camber plates have their line of travel fully left/right, by the 18-degree rotation of the 3-bolt pattern:

Steeda plates have the line of travel co-linear with the 3-bolt pattern, which means increased negative camber shifts the strut rearward in the shock tower:

Who cares about caster change? It is usually toe change that causes problems.

Yeah I get it. And I'm sure it's miniscule. But the enginerd in me is curious nonetheless.

The mustang changes toe very little with camber change because the virtual line passing through the lower ball joint and tie rod end is very close to parallel with ground. It makes it very nice to be able to run say ~2deg on street with zero toe, and -3 to -3.5 on track with out doing an alignment.

Strongly disagree. 0.6 degree total toe change between my street and track settings. I have the two settings marked on my steering rods. Wrote a post about it.
