if this was on a cossie, this would be the passenger side
the direction of the slots in the disc is the same as the direction of the curve of the vanes

If the cooling vanes in the centre of the disc are curved then they should face backwards.. In simplton terms, push a pencil into the centre of the vented part of the disc, if it leans towards the rear it's ok.

put like that, it's harder to explain it any simpler
See thats a confusing pic imo as grooves are not the same as internal vanes,which is the same pic as you have posted Steve!!
I would say imo that the grooves would work better like this and have seen my AP kits that have this and also the other way

Paul,
that picture is not confusing! I have already told you that the grooves in the face of the disc do NOT denote which side of the car the disc is fitted to, ignore them just focus on the venting in the centre.

Sorry Martin once i'd posted i forgot to mention that u said thatTrying to explain to Steve about said pic
I have taken the surface markings off all together so people only look at the internal grooves and the wording written along side them which explains it all.
If approved it will be swapped at the next website session on Wednesday
Interesting debate, lets hope I bolted my new rotors on the correct way lol.... I shall check and then admit embarrassment or otherwise shortly - I went based on the surface cuts

As Martin says, to remember- air vents backward from above, you cant get it wrong on any corner then n matter what the details on the faces do
I said I would admit it if I had them on the wrong way round... and i do... lol
The grooves faced fwd on the AP rotors when the vanes were facing back
I then replaced them with perf. friction ones and the grooves on the disc face back when the vents face back and I have put them on with the grooves facing fwd like the AP. Thus they are on back to front!
Sigh.. need to get the front end off the ground so I can swap em over. Bank holiday monday well spent
