The springs are UMI 2" drop springs. According to their site, they're linear with 130 lb/in - same as the 1" and stock height springs they offer. I don't know the range of travel.
I've had these Bilsteins for about 10 years. There's not a lot of compression or rebound, and they feel like they got more stiff once I lowered it some more. I think I want something that's a little more forgiving. I've been looking at QA1 or Viking adjustable replacements. Kind of wishing I bit the bullet and went with coil overs when I did the rear end.
