I just had these rotors pressed on & I think they are rotating in the wrong direction. This direction is front>>>>>

 

Ive seen them both ways. Pad material and rotor size makes more difference than slots/ holes.

 

I'm sure it probly dosent affect the performance as far as stopping distance, but I'm pretty sure these aid in cooling over extended periods of heavy breaking. So my concern lies in the direction of the slots/holes as it pertains to that.

 

The only real way to know (at this point) if they're on the wrong side or not is to ask the manufacturer. Different manufacturers will drill/slot rotors either way. Usually there's some kind of marking to differentiate the left and right sides, whether it be some sort of stamp or sticker that's on there before installation.

 

brembo says on my rotors that the inside of the slot should rotate to come into contact with the pad first.. had a nifty diagram that came with the rotors as well

also, logic would say so as it would allow the slots to do their job..

 

It's ok. I've seen them go both ways. Mine is the other way...

 

Holes and slots do not need to be directional. Many manufactures angle them the opposite direction...

Some examples:

Audi RS4


Wilwood setup on a Honda


Mercedes C63 AMG


I can find plenty of other examples, but I think you get the idea.
