I know many VX owners have use the R1 rotors with much success. I'm sure that they will chime in here.

I went with SP Performance drilled and slotted rotors with stock Isuzu pads. I don't remember why I went with SP rotors (just to be different?), but they have worked well for the past four or five years. I went with the stock Isuzu pads because they tend to last a LOOOOOONG time and create very little dust.

I know drilled and slotted rotors are useless on my VX because I'm never going to rally the truck and push the brakes hard enough, but dang they look cool.
