there is no right or wrong for Straight disk. so I dont know if yours are Straight or Curved vane.
If they are Curved vane then the holes have to point the same way as the Curved vane.

 

If not straight, then there should be a different disc for the left side and right side if you want them to aim the same way. I think pingu's post hinted at this.

I wonder if it really makes a difference? Each hole is independent.

 

According to the quote I posted from Brembo, it can make a difference...

 

Ive been thinking about a new mod, especially after what some of you guys have told me

Orienting the disc in the manner creates a centrifugal pump. The rotation of the disc causes air to be pumped from the center of the disc, through the vanes, and out through the outside diameter of the disc.

That does make sense.

Perhaps if the pattern is straight the cooling affect is limited to narrow bands radiating outward.

The staggered pattern of the holes may spread out the cooling affect over a more uniform pattern of the disc. If this jibes, does the forward or backward scheme make a difference?

I?m no brake expert, just considering how/why this works.
