I have a friend interested in getting my eibach pro kit from me and I was thinking of switching over to H&R super sports since I want to go a little lower. the eibachs ride really nice and I'm not sure if I want to give that up just yet.. do the H&R's have a rough ride or are they pretty nice? I am also considering getting shocks and struts at the same time so that might help the ride too. any input and advice would be great.. also if you have those springs on a 99+ stang, please post pics.. I'd like an idea on how much of a drop it is.
