Interesting observation I had. At an Integra meet I see a couple cars with those AEM OE replacement slotted/x-drilled combo rotors (how the pad has any surface left to contact is beyond me). But I found with all of them, the slots were going opposite the direction that other professional race cars like the RealTime ITR's have their slots going. Is AEM just stupid, or are all these people just putting them on the wrong sides?

edit- austin's pic of the RTR front driver side brake. It seems they have it set up so the slots move downward and it moves across the pad. AEM or the people installing their own slotted rotors always seem to put them on so the slots move upward as the pad moves across it.

Does it have to do with the multi-piston solid caliper requiring a different slot configuration than an OE single piston floating caliper? Or is everyone just doing their brakes wrong?

The direction of the slots also depends on direction of the cooling vanes inside the rotor. (or so I've been told)

But in most likelihood, it really doesn't make much of a difference whatever direction it is

I've wondered this as well... bump

 

this is the important part. it's the direction of the vanes inside the rotor. i think it differs from manufacturer to manufacturer which direction the slotting goes, though.
