I would like to get a set of drilled rotors for the 6s. Are they out there yet or are they still in the line of things to come. First I think they make the car look sweet. They should help the car since it is over 3000 Lbs.
If you want something of this sort, dont get drilled rotors, get slotted. Drilled rotors compromise the integrity of street-rotors more than slotted and slotted accomplishes essentially the same thing (if not more) with less structural integrity problems.
I had Brembo cross drilled and slotted rotors on my 90 Mits Eclipse/Laser turbo.
I had heard all of the stories about drilled rotors cracking and such. However, my rotors never cracked. These were not the cast holes as used in higher end car such as Porsche, instead, these were Brembo made rotors that were then drilled. I think they looked cooler than they performed.
The biggest difference in performance came from better pads. If anything, I hope that we can get larger rotors for the 6, slotted would be nice. Larger rotors and better pads will increase performance more so than the drilled rotor on the street. Now, in racing applications, the drilled rotor is better at keeping things cool as they have a larger surface area which can dissapate heat.
Be careful with Pad selection for a street car. Hi-performance and racing pads many times will increase braking distance. These pads require the rotors to be at high temps to work.
If you are not having problems with brake fade, OEM pads can be as good if not better than aftermarket pads for a street car. If I remember correctly Mazda designed the 6's brakes to be highly fade resistant.
Remember that tires stop the car, brakes only slow down the wheels. Changing to a softer compound tire will do more for braking than pads.
