No, a search didn't seem to help, so here goes:

I just received a set (front and rear) of drilled / slotted brake rotors. (Bling factor 8.5 ). But I have a question. There is no indication on which way they are mounted. Does it make a difference which way the slots go? Is there a "left rotor" or "right rotor"? There is no stamping on the rotors to indicate which is the left one, but I am assuming the slots would be designed to vent the gasses away from the center of the axle, right? Am I thinking correctly?

 

Basically it depends on how your rotor was designed. Think of the vents to move air, more than anything else, create a flow pattern. Some rotr's vein's are directional, like a propeller. Some less sophisticated rotors are strait veined, and can go on either side.

So I'm looking at the....




Hmmm.....




Right front. Right?

 

Yes, that is a right side rotor designed to run clockwise.

 

Next time buy them from some one you know I bought mine from Tire Rack and they were marked.

 

Actually no, if you follow what Alex told you you'd have learned that rotor can be run in either direction.

It's not a directional rotor.

As he rightly stated a directional rotor has internal cooling passages which should be run in one direction so to aide in passing air through the rotors center section. No stock replacement casting is truly directional that I'm aware of for this car. They are simply non diretional castings with patterns to appear directional.

Mmmmm.....


yeah....


didn't catch his name...


my bad.
