Want to know for sure? Take it in for an alignment checkup before you install the springs, then after. Then if needed, buy the parts, install them, take it back, and have the alignment done. To me, seems like alot of time (which is money) to spend on tracking down something that could be avoided altogether. Your best bet is purchasing the rear camber/toe kit, at a minimum

As for "drop it this amount, no that amount, no this amount", it is all subjective.
