New 5100's

Just ordered my Billy 5100's for all four corners, purchased them for better performance and getting a small lift. Given that I set the front @ 2.5,

-what aal pack would I need to level the truck?

-What can I do to avoid the infamous vibration issues and the taco lean?

-I've got VSC on my truck, does this need to be reset?

- Could I sport some 285/75/16 tires?

 

1) anything that gives you 1.5-2" of lift.
2) Vibrations are truck dependent. you might not even get them. Known fixes are carrier bearing drop and axle shims
3) http://www.tacomaworld.com/forum/suspension/41215-lift-vsc-answer.html
4) Depends on what wheels you use.
