If you turn the spring up in the rear it will lower the rear, but iam not sure what that will do to your rebound and that type of thing, and as for the fronts, stock raptor shocks just come with the cheap turning step things on the bottom of the shock, so there is not much you can do there. And those cheap lowing kits are for flat tracks and/or for extremely flat riding, because on a trail it would beat you and your machine up. Sorry that iam not much help other than telling your that there is nothing really dramatic that you can do to the fronts and that i am not quite sure how to "tune" the rear if you turn the spring, but one tip (and you proabably already know this) is when your in corners on the trail, just spin the rear tires as you are leaning....spinning the tires and breaking the ass-end free are how i get around the corners fast, anyway sorry for rambling....
