Help! Lowered springs for 2001 RX 2.5

[dickriani]

Hey, I'm wanting to lower my 2001 Liberty sedan but I'm not too sure on what I need as this will be my first mod!
I'm looking at getting H&R springs which are said to lower it 1-1.5" at the front and 1.3" at the rear. It also says that these springs are for a wagon - will these fit on a sedan, and if so will there be any difference!?
Also, will I NEED anything else for lowering it.

Cheers.
