Sounds like a nice kit. And I know you know this but that sye kit needs to have a cv (or dc) driveshaft which I'm sure it does since Tom Woods makes them. Ha and you'll only need to flares if you need the to pass inspection or for your own liking.
But you'll need an adjustable track bar (or at least a relocation bracket) and extended sway bar links and probably extended brakes lines. That's all I can think of right now.
Good luck with the lift!
