Is my AP discs the correct way?

A friend of mine pointed this out to me the other day, and thinks they are the wrong way.

Look at the internal cooling vanes, the grooves on the outside make no difference.

FWIW my old AP disks went that way round, PF ones are different. Internal vanes should draw air in from the middle and out on the outer edge.

Its the grooves i was talking about. On the OEM discs, the holes are pointing the opposite way to how the grooves are pointing on the APs.

Look at the internal vanes, forget the grooves on the outside, the direction of them isn't relevant

They look right to me, as nathan says its the inner vanes which count

you will know if they are if they are on the wrong way as they will get very hot. the cooling veins should be pointing up at the front of the wheel arch and down at the rear of the arch if that makes sense??

AP run the grooves on the outside of the rotor opposite to most other companies. I always have people telling me mine are the wrong way
