I had it set to ZCP ride height as per this thread:

It will sag a little after 1k kms so you might want to check ride height again after that. The damper will also break in a bit after 1k kms and the ride will be a bit less harsh.
Don't remember what height the kit came set at from factory. I would not assume that it's set to correct height from factory. Remember to also adjust your sway bar drop link collars so that the link ball joints are at the correct angles.
