if you just want to reduce the fendergap, like me, get the Eibach prokit. Plus it's good because I don't have any camber issues. if you want a nice drop, get the Eibach sportlines like AcCoRd97Lx.
I trust Eibach more than any other company. but other people can vouch for other spring makers for their cars.
you can see my drop in my sig (although it's kinda hard on a black car w/shadows on the wheel wells). basically I have about an inch fendergap. incidentally, I notice that Eibach under rates their drops a little.
