I don't remember what brand I had...whatever it was, don't get that one. As long as your alignment guy knows what he's doing, it should be fine. If he says he has to bend anything or structurally modify suspension components to correct the camber, don't do it. Make sure the shop has plenty of experience with lowered cars.
The shop I went to first was full of a bunch of morons, they're the ones that said "this kit will fix it." I had to go to another shop to fix the problems the first shop caused by installing the kit.
Spec R (if you're still following this thread): did they have to modify your rear control arms to get the kit in? They did something to mine, I'm not sure what...i imagine that was part of the problem right there.
The moral of the story: don't be a dumbass like me and let other dumbasses install stuff on your car.
