IMO if you want a 2" drop, go with dropped spindles. If you only want 1" you could get by with lowering springs. The front suspension only has 3 1/2" of travel, so once you start dropping it 2" with lowering springs you're probably going to bounce off the a-arm bumper a lot.
What size tires do you have on front, and what is your wheel offset? Anytime you lower a car you're more likely to have rubbing problems, but not necessarily. If you lower the car 2-3" and your tires are more than about 67.5" wide on the outside to outside, you're getting close to rubbing on sharp turns at full lock. Keep in mind that if a suspension compresses on a sharp turn, it's just like having a front drop.
