ANY time you lower a car, you are going to need an alignment. On the strut front suspension, you will get negative camber and toe out. The toe out will kill your tires and make the car twitchy on turn in.
On my car, as with any srt-4, the amount of camber is never the same, even side to side. Before my alignment after I installed my springs, I had -1.1 on the driver side and -0.7 on the pass side and .35" of toe out.
Also, I HATE camber/crash bolts. They are a smaller diameter bolt shank than stock. They work, but if you plan to autoX or road race, I would slot your struts instead, that is a better way to do it. Camber plates would be the best choice, but they can be $$$, slotting is pretty much free.
To whomever asked, the SRT-4 does not require endlinks with just springs.
