State of Confusion

I am putting drilled and slotted rotors on my Dakota, and ordered a set of slotted rotors but they are not marked left/right (driver/passenger).

I have heard two different people say two different directions.

A dirt racer friend of mine says they mount the slot // with the point toward the front, another guy said \\ slot points toward the rear...

Does it even matter which direction they go?

No, no label of any sort. The rotor does have internal cooling fins that the holes are drilled into, the slots do not go deep enough to reach the fins.

If the grooves on the outside are facing the same direction as the internal vanes, then that is your left or driver side rotor. ignore the holes and slots that are machined into the rotor. the vanes inside can be in the same direction, they may not be. they may be straight vanes. if the vanes in the middle are straight, then the rotors can go on either side. http://zeckhausen.com/how_to_properly_install_rotors.htm Photobucket sucks
