07 Showstopper

Hey guys- this is my first post but I've been reading threads on here since I got my stang last year. You guys always seem to have the answers I'm looking for! Anyways, I have a question about lowering springs for my 07 v6. I have Steeda Ultralites on the car right now and its stance is way better than stock! However, I was hoping that it would be just a little bit lower. Ive seen pictures of stangs with eibach pros of them and it sits really nice, but I also dont want the ride to be unbearably rough. So if anyone has driven stangs with both of these setups or can tell me how the ride is with the Eibach Pros vs stock thatd be great! Also I live where there is a fair amount of steep driveways so I'd also like to know how the Eibachs are in regards to clearance. Thanks! (and sorry that the question is so wordy lol)

WIth the Eibach kit you are going to have to do shocks/struts sooner or leter if you dont want the ride to be hell. The steedas were designed to work with the stock stuff and are only supposed to get better with aftermarket shocks/struts.
