Ya the 3" lift is pretty stiff when you first install it.
Calmini tells you in the instructions to flex the coils regularly so they settle down.
I installed my kit just before Christmas, and it rides a lot smoother now since the coils have settled.
The Camber corrects itself when the front springs settle in. My camber was pretty bad when I first installed the kit. The tires looked like this \ -o- / but now its almost perfect.
When I build my front and rear bumpers this spring and install them I'm sure the ride quality and camber will improve even more.
That’s my tracker in the middle. You can see that the camber is pretty good.
