*Did you remove the dustcovers from the stock shocks?
*Did you cut the bumpstops in half?
There are all instructions in the Skunk2 coilover set.
You will just need to unload the spring by threading the nuts down, you will lose shock travel but it shouldn't be enough to damage the shock. If you already have them all the way down then you are screwed. Will need to find shorter springs or modify.
EDIT:
Look how damn nice I am, see below. Should help a little
Err, i guess they're called "jam nuts" But whatever!
You can take the bottom mount completely off and unscrew the 2 "jam nuts" since you'll have the mount adjusted all the way up anyway.
I'm stoked on the ride but not stoked on how low i can go once i decide to lower the back as far as i can.
