Fitted mine last week and had it aligned today.
I just took it that the rear was factory set also and just counted the number of turns I made to both shock and spring seat.
Hope this helps, I had no knocking issues on the drive home and I know the rear springs had some preload.
Think I need to play with the shock settings as it was a little jumpy on the front end, going to go a bit softer, other than that the ride was very good, seemed to ride average bumps/potholes better than before.
