you can do rear camber, but it'll run ya around $300 done (parts alone are $250)

anytime..

 

On double wish-bone suspensions, the front toe would result a toe-in condition after a lowring job is done. The more you lowered, the angle would be off more and be out of spec.
But for 2001 and up, as the front are modified MacPhersons', the toe angle would not change by much since lower control arm length are all unchanged. (similar to Toyota) but the rear would alter by 0.3 to 0.7 degrees due to multi-link system is used.
so to save your tires and $$$, alignment is much needed!!
