Default Rotor Cracks Opinions Please

With the McRae Sprint season coming up I am after some opinions from those that know about rotors.
As well as the cracks shown in the pics there are also some other small cracks like this in the rotors not shown, so should I be concerned and get new rotors asap or will they last longer and not worry to much right now ??

After seeing the results of a cracked rotor disintegrating at the bottom of the straight at Wanneroo many years ago and the car hitting the wall at about 160kph I'd fuck them off real fast but internets experts and brake experts are different so you may get better advise here than at a specialist brake shop.

Better to replace the rotors than fix the car. They don't look great.

Cracking in anything is normally not a good sign. I would say in something as important as rotors it would be best to replace them. Better safe than sorry.

Weak sauce! Had to drive back from barbs to freo with this cheese grating my pads one night..



Change them mate, I was expecting to see some little spiderweb like cracks that are no big deal in my opinion but they look pretty serious and could end up worse.

Rallysprint isn't the place to chance it on brakes..

Thanks for the input guys point taken. I think I just needed a little nudge to do it.

This is not a nudge, and it could be my eyesight, but,
those marks in the photo could be scoring, a scratch from a stone caught between pad and disk.
If so it 'may' be harmless - ' it will buff out.'
The first mark could be either, the second more likely a scratch, the 3rd looks like a fracture.
If they are fractures, replace immediately, a fracture can spread catastrophically.
