04 front disc rotation.

i think i know the answer to this question but.
i gave my bike a bloody good clean over the weekend and noticed tiny little arrows on the disc look the wrong way around!
the last 2-3 years of owning the bike i have never noticed and it hasnt caused any problems, ive even done a track day on them!
regardless i will probably have to swap them over.
what do you think?
its not easy to see but you can see the arrow on the bottom left of the disc.

 

probably the wheel has been put on the wrong way round..?

 

wont make any difference really,as long as the tyre is on the right way,just check that.

 

i know the tyre and wheel are on the right way around because i done it myself
