Yes, it will stress pretty much everything. You loose travel, which equals a harsher ride. A harsher ride equals more wear for every mile. So things like bushings will go bad. Even ones that don't have suspension movement like subframe bushings. But things like control arm bushings will now have all the movement happen more quickly as suspension travel has changed. And anything related to geometry will have the toughest time. So tie rods, ball joints, etc. Even steering racks seem to go more quickly. And shocks will go more quickly as well.
Now the key is, they will go more quickly. These are all wearing parts anyway. They are going to loosen up on a high mileage car as well. So it's just going to happen more quickly, but it will happen to any car. Now you could go with urathane bushings and realistically never have to deal with bushings again but it's time consuming, expensive if you don't do it yourself, and has a harsh ride, squeaks, etc.
I've slowly gone up with my drops. I find the difference between having your car dropped and having your car slammed is a big one. And a minimal drop like prokits really doesn't have any of the problems a lowered car would typically have.
