Has anyone cracked the OEM rotor yet?
 

As the title states, has anyone cracked their OEM rotor yet? Just trying to get a feel if I need to bring a second set of front/rear rotors to an upcoming track day event. Please also state which brake pads and tires you're running.

I'm currently on XP10 both front and rear, OEM rotors, and 215/45/17 Dunlop ZII.

I'm running Hawk DTC-60 in the front and HPS in the rear. No cracks after 2 events. normal heat checking is present, but nothing of concern. Regardless, I keep spares at the track.

We are running hawk DTC-30 two weekends so far and no abnormal signs of wear. I to keep an extra set with me.

I know Dave ror has. He's a mod here.

Our OEM rotors were swapped out because they're just on the verge of cracking. We already had our AP Racing BBK ready, since we anticipated the cracking to eventually happen.

We've gotten some real good heat checking from the past three weekends of hard use (4 days at the track and two days in the mountains). We will be replacing them this week.

Do the rear rotors get hot enough that there's risk of cracking?

Zero microfractures on our rears. We've had the same ones on since the car was purchased.

Trying my best to avoid cracking/delaminating my OEM front rotors...

How's that routed at the front?
