Sometimes you have to have a second alignment done once the new springs settle/sag.
I noticed a few months after I replaced my rear subframe bushings with M3 units... that the rear end felt very squirrelly at high speeds (>135 mph to 170mph). So a four wheel alignment is always a good idea. I'd say do one every year or so.
