what is the proper direction of drilled and slotted rotors

I've had different people tell me different ways. What's the right way?

I've seen them both ways.
I'd like to know this also.

Re: what is the proper direction of drilled and slotted rotors

My rear rotors from wilwood have an arrow on them pointing so the slots are going against the turn of the wheel. But I called Performance Online and they were telling me the slots should go with the turn of the wheel bc it will eat the breaks up faster.

IIRC so does Power Slot/STOP-TECH.

I cannot verify which way is the correct orientation of the slots cut into the rotor face. However, if the vanes inside the rotor are angled or curved, the angle should be sweeping back to pump air from the hat to the outer edge for proper cooling.

Yea I have found documentation on them about the internal vanes and I can understand that. It's actuallly a functioning design of the breaks. Mine are straight.
