Trust me I have pictures of Failed powerstop rotors, btw do you know where powerslot and powerstop gets its rotors from? Brembo, and I am not saying that putting cross drilled rotors is negativley affecting you car, I am saying you could do the same thing with brand new non slotted or cross drilled rotors.
It is true that holes do help cooling some, however thoose rotors also run at a higher opertating tempature due less mass, which means will they cool of faster they also reach high tempatures and that is not whan I want happening with my brakes. When you heat and cool something quickly this is what happens.



Now will this happen in daily driving? No, but take you car to and HPDE and by the end of the weekend that it is very possiable... oh wait you said cross-drilled powerstops right?



Oh read this one to http://www.teamscr.com/rotors.htm

Now for street driving and of course bling ther is nothing wrong with these rotors however saying that they make you stop better than standard rotors is misleading if you have not test your new cross drilled rotors agains new non-crossdrilled rotors, then you cannot make that statment... oh and you asked this when I said I never faded my stock brakes "but what about new pads, new c-d/s rotors, and new brake fluid?" Why would I want to spend more on money on something that is not going to give me any better performance. I can get new front rotors for under 25$ I can get new crossdrilled rotors for 125$, with no proff they actually do anything better. Also rally drivers and supposidly porsche's run cross drilled rotors because they perform better when they are wet, and for a rally driver thats a big thing.
