Those are street cars and drilled rotors look cool. My friends that run their Porsches on the track crack rotors all the time. The Porsche rotors might even have the holes cast into the material, which is much stronger than your typical cheapo rotor with holes drilled in it.

I also know that the motor doesn't belong in the trunk. Hell they know it too but pride in the 911 line keeps it there. If they put the 911 motor in the mid-engined Cayman it would be the faster car.

 

No, actually they aren't. From what I can recall, carbon/ceramic or carbon/carbon brake pads and rotors don't react the same way as "regular" cast iron rotors with appropriate pads. When the carbon/carbon brakes heat up, they do gas out, whereas modern iron rotors and pads do not.

 

And KVR drilled rotors are the same as Porsche? Or even made in the same fashion? Give me a break.

This forum isn't as much a pissing contest as it is a place where you will get called out on if you say something that needs defending.

 

They aren't what? Brake rotors or serve the same purpose as brake rotors? What relevance was this answer to what you quoted me?

 

That is what I just said. Cross drilling in carbon rotors is necessary. Cross drilling in cast iron rotors causes cracking.
