drilled rotors??

I wouldnt get those, if you want them get a top brand name like brembo or baer. I've had my Baer Slotted/Drilled/Zinc Coated rotors on for over a year and there are no cracks.
 
It also depends on your driving, cause they always seem to say don't use cross drilled in road racing. I would check out the power slots website they have a series of rotors that have dimples that give the appearance of cross drilling.
 
The problem with the drilled rotors is that they are made to release the brake gas to help reduce brake fade....but the trade off is the holes make the rotor weaker... So I would not buy a cheap set of drilled rotors, if I went drilled you need quality parts.
 
The ones on Ebay are pretty much made in china. I have a couple of friends that have them and have had no problems at all (we do a little track every once in awhile). I use Hawk rotors and I cant' really tell the difference between the cheapo's and mine. They wear the same using Hawk HPS pads.

It's your money, spend it the way you want...
