07+ sentra - eibach pro-kit?

[unmei]

i really want to lower my 08 sentra sl. everybody says eibach pro-kit because i don't want to change out the stock struts and my local roads suck, so i dont want to go too low. are there any alternatives? i am having a hard time finding stuff for anything but the se-r. also, do i have to do a realignment after i install new springs? i'm kinda a noob to imports please help me out.
