Bought these ages ago from gorilla, do these rotors face this way...

!
 
or the 'other' way.
 
I had mine installed, and the are the 'other' way. ABS works fine at speed but triggers at very slow speeds. Mech thinks the way the discs are facing could be the cause. (As I know it not the abs sensors - had those replaced!)
 
 

Your picture, that's the way they're meant to face.

Yep that's the right way 

Thats the right way round for sure,
but i did read an article from another manufacturer stating their discs can be reversed (similar pattern) for better performance but reduced pad life and increased dust.
cheers

Thanks for the replies, i'll get them changed around.

love the povo paint diagram lol

^ A work of art.

whats the cooling vane design of rda rotors? Some brands of rotors are designed to have the slot on the face angled backward and a few have them facing forwards. That doesn't really matter much as they just sweep across the face of the pad. What is important is the direction of the cooling vanes inside the rotor. if its a curved/angled vane they should be angled towards the back of the car, so that as the car moves forward and the wheels turn, the rotors suck air in through the center hub area and push it towards the outside of the rotor. If the cooling vanes aren't angled/curved but rather straight or kangaroo paw like DBA, then it doesn't matter which side they go on, and they can go on either side or whatever left/right they are marked from the manufacturer if they are slotted.
