From these pics, that makes sense to me given my tire wear; however, my alignment shop requested the need for more caster adjustment.

The second image is caster adjustment

 

Either you misunderstood or your alignment shop does not know what they are doing. Caster is not adjustable on most modern cars. The SC included. Now, caster can change as the alignment is done. However, the caster is not independently adjustable. Caster used to be adjustable back in the days before power steering. It gave the car a certain steering feel.

 

Castor killed one set of my fronts. My buddy did my alignment so now it's not as bad. I'm running negative camber just from lowering, so I don't plan on installing the SPC or K-Mac kits. I have both the SPC front arms and the K-Mac rear camber kit for sale if anyone is interested.

 

To be clear, these upper A arms have both castor and camber adjustment. Specs are available on the link on the first posting.
