Is this on right?

Go be the internal vanes. They cool the rotor. If they come straight out from center of rotor, then the rotor can mount either way. If they come out at an angle, then you want to position the rotor so the internal vanes trail from the direction of rotation as air is pumped from the center hat outwards.
If this is a cross drilled rotor, the angle of the drilled holes does not matter as they don't cool the rotor. Go by the internal cooling vanes.

Vented?Oh you mean is there vents on the inside of the rotor?Well i'll go look tomorrow night,so from your last post if they are vented the vents go towards the foward rotation? Well they are slotted and dimpeled not drilled.Thanks they are EBC 94+ rear cobra rotors and calipers and 03 EBC front rotors.Along with EBC ceramic pads all the way around! I also have the cobra MC to install with the 3-2 conversion,that will be done when i pull the motor next week for my newest mod!So stay tuned i'll be starting a new thread and posting pics towards the end of the week when the parts start showing up

Yeah, the internal vents are what cools the rotor. If they are straight, you can put any way you want. If they are angled, they must point away from the direction the turn. In other words the vents on the inside of the rotor on the top point to the back of the car.
I am pretty sure cobra rotors have straight vents meaning they can go on any side...in which case the way you hqve it now is fine.

Here ya go. Picture is worth a thousand words

In this pic, the rotor on the right would spin counter clockwise and go on the drivers side if the cutaway side of the rotor faced outwards.
