Just installed my ZZP MPS and im curious its a 8 rib pulley which ribs do i skip using the stock 6 rib set up?

You belt will just settle in where it wants to ride. Start with it in the center and It will move to where it wants to be. I have seen them run in all three positions. Inside,outside,middle

Mine sits on the 6 closest to the S/C. The shop that pulled it off put it on the wrong ones and it frayed the belt just alittle bit.
