Adjustable camber arms...alignment time! More parts?

[longlivethez]

I just had some SPL adjustable camber arms put on the rear of my '14...naturally, I need an alignment. Badly.

No prob, called best alignment shop in town...he's saying something about cutting into the sub frame in order to be able to get the toe back in spec? Something about a larger cam eccentric or something?

Can someone shed some more light on this for me? Any help greatly appreciated. I'm pretty lost as suspension and suspension tuning is...like...this huge dark area to me since no one ever talks about it! Everyone and their mother talks about turbos and exhausts and all that non-stop but suspension tuning? NOPE!!
