I got mine from KVR Performance. They are Brembo cross drilled.

I'll crossdrill/slot them for $25 per rotor, but you may want to get them from someone else if they stock rotors for a CA20 car. I really wouldn't recommend drilling rotors though. The drilled rotors can form stress cracks at the holes which can cause the rotor to come apart. Cars the have drilled rotors from the factory have the holes cast into them when the rotor is cast. The last time I had 1=2's car I noticed that one of the rear rotors apeared to have a crack forming in it and it isn't even crossdrilled.

Hmmm, interesting.....I've had my cross drilled rotors on for over 3 years now, and haven't had any problems.....even had the fronts ones turned once about 2 years ago.

"
If you cross drill one of these vented rotors, you are creating a stress riser that will encourage the rotor to crack right through the hole. Many of the rotors available in the aftermarket are nothing more than inexpensive offshore manufactured stock replacement rotors, cross drilled to appeal to the performance market. They are not performance rotors and will have a corresponding high failure rate.
Recently, primarily due to the high failure rate, more and more of the aftermarket rotor suppliers are now slotting the rotors as opposed to cross drilling them. Slotted rotors are less likely to fail, but really do not offer any performance improvements over your factory rotors. It is important, however, that you do not confuse an aftermarket cross-drilled rotor, with a cross drilled rotor that has put the holes through the faces during the casting process. If the cross-holes were formed during the casting process, they may be less prone to failure."

it was my understanding that the S13 rotors were the same as the S12

Miy front ones are vented.....and still never a problem. What I found out from KVR was that they get the rotors from Brembo, and then KVR either slots them or drills them.
There prices aren't too too bad...think I paid around $70 each for them. Not bad compared to other companies out there doing the same thing.......I looked at getting some for my Maxima, and found out they were well over $100 each from Stillen for a OE replacement drilled rotor.

I did a pair for my old Cavalier, but I wouldn't bother doing it if I could buy them.

$119 for a pair of slots?! Holy shit what a steal! This site is bookmarked.

I have heard this to, apparently blind holes lessen this affect (basically only drilled half way through) but really just slots is all you need, just somthing to wipe the pad. I have neither cos i'm to lazy right now to get my S15 rotors slotted.
