What class are you running in? I ran in ST and DSP for a number of years, where you are restricted to an upper or lower method of adjustment, not both. I found that the best solution for these classes was either the fixed Shine Racing upper plates or the adjustable plates from Ground Control. I'm moving to SMF this year, and will be adding lower control arm extenders to get a little more negative camber out of the fronts, and use the ground control plates more for getting caster a little closer to stock. For the rears I used SPC toe shims to add a little bit of toe out.
