How much for the whole set up with that Stillen package?

If your looking for Rotors you should consider the DBA brand, a little Aussie engineered rotors for your Aussie engineered Camaro!

definitely a future mod I would like to do.

So is anyone running different cross drilled rotors that they recommend? If so, where did you buy them?
Why do you want to install cross drilled rotors?

I'm guessing for cosmetics. I would want a set of drilled/slotted rotors!

What's the difference between 1-piece and 2-piece? Lighter and better cooling?

The primary benefit of a two piece is lighter weight so less rotating mass and improved braking. The slotted and cross drilled is a bit of a carry over from older pads that emitted gasses that reduced brake efficiency. Modern pad technology has eliminated that issue. The holes lighten the rotor and in theory improve cooling. Cross drilling can create a number of issues in cars that are driven hard on track. That is why I was asking what the the OP's goal was.

True, cross drilled rotors start to crack under hard driving conditions.

agreed, but they do look cool!

Seriously though, the Slotted rotors are more durable than the drilled rotors, though the drilled may have cooling advantages over the slotted, i personally prefer durability over flash.

Under hard track conditions, yes. For street driving (even fairly aggressive use) this is not a problem for good quality cross-drilled rotors.

If cracking is still a concern, wait until later this week when the new Stillen J-Hook rotors debut! They will have all the high-speed "bite" of cross-drilled rotors while negating concerns about cracking.

In SSCA racing many classes prohibit the use of anything but an OE rotor. You'll see vette and Vipers tearing up the track with OE calipers, rotors and race compound pads. Cross drilled and slotted rotors are more of a fashion statement held over from the days when pads gassed so badly they reduced braking power. They do look really good.

If you car is going to see track duty, OE or plain faced rotors will do the job with a good race compound pad. I am a HUGE Cobalt Friction pad fan. I think they are the Gold Standard and all our Pedders track cars run on them. If you are never going to see the track slotted and cross drilled are fine. For the track my personal preference is plain face, but I certainly would not point and laugh at a slotted rotor for track use, but leave the cross drilled for the show circuit unless they are extremely high quality as you would find on a ZR1 or true exotic where the holes have been part of the original manufacturing process.

Just a couple of notes. Both J-Hook and slotted rotors are used in professional motorsports all over the world. I've seen a lot of plain-faced rotors as well, mostly in series that don't allow changes. The increased pad bite, especially from J-Hooks, is difficult to take away from the better drivers once he/she experiences the improvement.

Also, no rotors are made with cross-drilled holes as "part of the original manufacturing process". Without exception, they are all drilled -- yes, including those mythological Porsche rotors that are claimed to exist. The ZR-1 uses carbon-ceramic rotors, and those holes have been drilled as well (before siliconization anyway -- after that, they are almost as hard as diamonds!).

I do not recommend cross-drilled rotors for the track either. But J-Hooks and slots work VERY well (where allowed).

Chris,

you are the brake maven, but you are dead wrong in this statement.

The ZR-1 uses carbon-ceramic rotors, and those holes have been drilled as well (before siliconization anyway -- after that, they are almost as hard as diamonds!).

That is ABSOLUTELY part of the manufacuring process and WHY THEY ARE SAFE FOR TRACK USE.

Maybe we are misunderstanding each other? The CCM brakes on the ZR-1 are drilled after carbon vapor infiltration (when they are still carbon-carbon) and before final siliconization (where they get transformed to carbon-ceramic). After that, only grinding with special tools can be done. A drill doesn't stand a chance afterward -- it will walk and break. The holes are not laminated in, if that is what you are referring to.

Drilling carbon-carbon or carbon-ceramic does NOT induce stress risers like drilling iron does. They are completely different animals. If a "ceramic" rotor is OK'd for track use (not many are, by the way), drilling will not make any difference at all in longevity. In fact, it just might help at elevated temperatures to hold off oxidation (the REAL enemy of ceramic rotors) just a little bit longer. Ceramic rotors, if they ever were to crack (very unlikely), would no sooner crack at a hole location than not. It's a little weird that way, but what happens in iron is not applicable at all to ceramic.

Were you referring to something different?
