Cut 1/2 a coil off the OE front springs and buy some McGaughys 2" rear drop springs ($200). I have heard they only actually drop about 1 1/2" though, but you could just a 1/2 coil to a coil off of them if it's not enough for you. With this you would end up with 1"-1 1/4" front drop and 1 1/2"-2 1/2" rear drop. It would look and work perfectly fine. Buying an aftermarket kit (if you can find one) for this small of a drop is unnecessary and a waste of money, IMO. I've lowered or lifted almost every car and truck I've owned (couple dozen or so), so you can take my word on this.
Just make sure to get it re-aligned.
