Look at that image. Tell me what you all think. I'm gonna put new rotors and pads on Monday. But it's deep!

Curious was it a rock that made that
my friends 991 turbo S had the same happen to him from a stuck pebble
on his pccb rotor very expensive mishap

You’re referring to the groove I assume. I’ve seen dimples on rotors that are used to judge rotor wear. I wonder if this is an intentional groove to monitor wear???

Also the grove wont affect performance. I would pull the pads and make sure nothing is stuck in here and just keep using the rotor if they r within spec. The rotor will wear to the grove eventually. No need to waste $ if they still have the correct overall thickness.

Thats not the end of the world.....no need to replace unless the whole rotor(s) have a rig on them.....I would pull the caliper off and get the stone out of it! It's an easy job to do!

Happened on my VW, the head of a sheetrock screw somehow got between the pad & rotor. Plucked the screw out, put it back together, ran for years without a hitch.

Follow that little groove right around to the bottom side of the caliper/pads and you will find something stuck in there....

That had to make some noise as it was happening but I've seen this, especially when VIR used to have a pebble paddock.

Yep a rock.
I swapped out the whole rotor and pads at a whopping 68 bucks on Amazon!

That brake disk should go on the driver's side...

at 68 bux for the set, I doubt they use uni-directional rotors. Probably just a single part number for both sides, unlike the better brands.

This ^
Many manufacturers now utilising uni-directional rotors.

Amazon today $248 for a pair. Pad looks wrong size, AZ does not say they will fit. Maybe the rotor fits, but the pads in kit don't work, you use original/OEM/aftermarket-brand replacement pads?

YMMV

Chevrolet has been doing this for years with Corvette.

Lotus Elise/Exige is another one I distinctly remember.

I beg to differ. I have the set. And the pads fit. You can't tell a book by its cover
Pads perfect fit I just got lucky.

So folks. The rotors and pads fit for the set I posted.
