How much did you lower the suspension? Did you change anything else on your suspension? I lowered mine 1.5" (14K miles ago, Roush Springs) and it changed the whole suspension geometry and affected the front end camber. I never thought to have the front end alignment checked, but I recently found that my tires have been wearing on the insides which indicates that the top of the wheels are pitched inward. Today I installed caster camber plates and I am going to get the front end aligned on Monday. I also had to adjust the pinion angle but did that at the same time as the springs. I am just curious if you needed to do anytrhing else.
