Two on each side (one kit). I wouldn't skimp with just one offset per side. Because if you were just short of what you wanted, you'd have to take everything apart and redo the press-work. Not worth the cost of another kit vs std bushings.
I was able to get 5 deg positive caster, 1 degree of negative camber. So, lots of adjustment. If I went with less camber, could have got even more caster!
**Just made a diagram with bushing installed to help explain
