Steeda Bumpsteer kit, and X2 ball joints might be needed, along with caster camber plates, and ofcourse upgraded dampers. Handling will be improved rather than destroyed. The lower you go, the more problems that you could have.

That's about the gist of it. Bassman was right though and I'll splain below.

Generally more than 1.5" of lowering in front pushes you past the point of diminishing returns and starts directly causing handling problems you didn't have before. Some of those problems are really hard to identify but they're easy as hell to feel if you know what it can be like and it becomes obvious in any hard driving like racing or tear-assin'... things like increased tread squirm, increased push and a below-ground roll center, blah blah blah. Suffice it to say that unless you go the whole coil over and tubular arm route that more than 1.5" drop is a no-no. If it doesn't impact your daily driving... cool, but I'd call it at the 1.5 mark.
Below an inch you'll start feeling the negative effects and the extra half inch is pushing things to what I'd call a streetable limit. It's not a question of what's possible it's a question of what'll last and perform and the two don't often meet.
As for Eibach... meh... some good some not. I prefer either FRPP F springs or H&R Sport. Consult the spring rate guide in this forum for an idea of what's what.
