Front Passenger - Album on Imgur I was told that the front rotors are directional - do these look like they're wrong?

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

They look fine, not sure what your concern is?
POST 3Original post
Yep, I agree. They look fine. No cracking.
POST 4Original post
Yes, but are the holes going in the right direction on both sides? It seems like they are the exact same rotor mounted on both sides, and the CS has 2 different part numbers for Right vs. Left?
POST 5Original post
Mine look like yours. Fronts have a pattern that would be side specific. You may have 2 left rotors ?? Rears seem to be drilled without direction.
POST 6Original post
They look ok to me, but I would suggest cleaning out the holes to help with cooling.
POST 7Original post
AFA wear goes, your's are fine. But I think you are right - the front passenger side is wrong - venting wise. The hole pattern is reversed. So it looks like LF & RF actually are the same part. It probably doesn't matter much for street driving, but on the track, it could affect cooling of the rotors and pads.
POST 8Original post
The hole pattern is directional so each side. The pattern should slant to the rear. So, you have two of the same rotor. There are internal cooling vanes on the rotor that would be spinning in the wrong direction on one side. So, for track driving this would pose a problem. For street driving, irrelevent.
POST 9Original post
OK, so for doing track days, I should go ahead and get all 4 replaced, judging by the shape the rears are in as well?
POST 10Original post
Not a bad idea.
POST 11Original post
I'd start with just the fronts. Milk those depreciables as long as you can. If you are just starting out with track driving the brakes will be fine for several events after you correct the venting direction.
POST 12Original post
As stated above clean out the holes. A T-handle allen key works well for this, but a small screwdriver will work as well. I cannot see the vents clearly in the picture. You need to turn the wheel facing outward and take a picture straight on to see the vents. I don't see any cracks to be concerned about.
