I used SP Performance drilled and slotted rotors and stock Isuzu pads and haven't had a problem with either of them at all.

If you can't find the Isuzu hub bearing tool then you can alter a Ford (I believe) hub bearing tool. I altered the Ford one and have pictures if you want to see what's up with that.

Also, if you haven't seen it yet read through Kenny's thread on replacing the rotors and repacking the bearings. I had that and the instructions from Planet Isuzoo and everything went smoothly and easily.
