STanner,
Your 2002 may or may not need camber cams to correct the alignment. In mid year they changed the upper control arm mounting bolts to a style that can simply be repositioned and tightened back down in the correct position. If you have the earlier build, then the cams on the bolts will need to be installed to adjust it.
You can tell which style you have by looking at the bolt heads on the upper control arm mountings. If the head of the bolt has an eccentric cam on it, you have the early style, but if it has a thin steel "flag" that just keeps it from spinning, you have the late style.
All mid 2002 through 2005 ST's do not need any additional parts to correct the alignment, just a little additional labor, but try telling that to an aftermarket shop that makes money by selling you cams.
