Just recently picked up some of these for the LNF. I've already tossed the box and didn't see any markings on these things and after doing about an hour of searching the internet I can't seem to get anything to tell me if I need to put them on having the slots facing a certain direction.

I understand these rotors are NOT directional vaned rotors, just really wondering if the direction of the surface slots matter or not with these.

 

It doesn't matter.

 

Thanks that's all I needed.
