These are OEM rotors with 4 driving schools on them with Pagid yellows - I think I can get one last weekend out of them but just wanted a couple opinions. My next weekend it at MidOhio on 4th of July weekend.

 

At least one more then check them. Might get 2 weekends but watch it because the cracks accelerate the longer they get.

 

Looks ok for another weekend as far a the cracks go.

Wear pattern seems odd to me. Maybe it's just the swap between street and track pads?

 

Good to confirm I can get one more weekend! What exactly seems odd in the wear pattern? I do go back and forth between street pads (OEM) and the track pads (Pagid yellow).

 

There seems to be no contact between the pad and the rotor near the hub (note the rust, rather than metal) and something similar near the outer part of the rotor, but less pronounced. For sure, you will want to swap pads and bed them in before using them on the track. Hopefully, that will eliminate the no-contact regions.

Edit: If it were me, I'd buy a set of rears and take them with me to the track. It takes only a few minutes to change them, and the time is coming soon anyway. Could save your weekend if the cracks start getting more noticeable.

 

I'm sure they will be fine... but who skimps on brakes LOL

 

ymmv, but I'd change them. Unless the track you're running at doesn't require you to brake from 160 to 40 a bunch. And Mid Ohio does. My reasoning is that the second pic makes me think that some of those cracks are close to mating with adjacent holes. And that's what you can see. That said, I'm cautious with my brakes and you'll probably be ok. I'd check after every run group closely. Racing a light momentum car as opposed to our fat-assed cars, I'm passing more cars under braking and want the optimum set-up. Just my 2 cents.

 

I'm no track pro or anything, so take that for what it's worth. That being said, you're going to have to replace them anyway, why not have the piece of mind of knowing that they're not going to disintegrate and send you into another car or wall and suffer a large amount of damage or worse. My thought is if it's bad enough for you to ask the question, then just replace them. If you do try to get another weekend on them, good luck and as others have said, be sure to check them after EVERY run group to see if the cracks start linking the cross-drilling.
