Let me clarify what I am saying. You want to set the upper control arm shaft angle the same as the stock Camaro, NOT the Caster, that you can set at anything you want by bringing in or out the upper control arm shaft with shims.

What I am referring to is the angle of the sub frame when it's welded to the frame. If you were to only be looking at how it "fits" to the frame you could weld it in too low or too high in the front and then you possibly wouldn't be able to get the caster you desire by shims but would have to get an offset control arm shaft to do it.

If this angle is set up properly you can align it just as if it's still on the Camaro.
