skunk2's come with 400-550 spring rates, which makes it a very bouncy and siff ride no matter what kind of shocks u get.

ground controls come with softer rates of 300-400 (around there) or u can custom rates. these softer spring rates makes for a softer ride.

if you like to autox or road race get skunk2's or ground controls with custom rates. if u just want a drop with adjustability get ground controls or ebay crap.
