Slotted Rotor Direction
 

Can anyone varify which direction slotted rotors are supposed to face? Do the slots face towards the front or rear of the car?
Thanks:question:

<--front; rear-->

What kit are you using? I know that the Wilwood's have an arrow stamped in them to show rotation.

It depends on the brand of rotors as to what direction the slots are milled into the friction surfaces. You should orient your rotors based on the direction of the cooling vanes, not the slots, assuming they're directionally vaned rotors. For a directional vane rotor, the cooling vane should slope like / or ( at the top of the rotor looking at the outside face of the rotor.

Most quality rotors will run the surface slots opposite the direction of the cooling vanes so that they intersect at near perpendicular angles versus running parallel to one another and reducing the rigidity of the rotors and possibly increasing NVH.

I'm doing a LS1 front and rear brake conversion on my 69 camaro. I haven't bought any yet but am shopping. I see cars at the shows, some with the slots facing forward like in the pic and some facing rear. I never thought about the direction of the vanes. Thanks for the info.:thumbsup:
