Are these rotors more prone to stress cracks and warping that has plagued these types of rotors (drilled)in the past or are they of pretty solid quality? Im lookin at the 13" variety for cobrasand dont want to have to replace these prematurely.

Thanks in advance,
Brad

 

We haven't had any problems with them. Basically, these are better for racing than for daily drivers, because they are lighter. I wouldn't necessarily recommend them if you're going to put them on a car that you drive all the time. That's not to say that they won't work if you do plan on putting them on a daily driver. As long as you're not consistently going 120 mph and then braking really hard (and doing it over and over and over), you're not going to have a problem with them.
