drilled and sloted Options

[Dragondog]

where is a good place i can get drilled and sloted rotors......no i wont do it to standerd disks......i found a place in ca that sells them for 69$ for frt pair what do you think others for 107$ a disk

:lol:

I just say what comes from research, race teams, and what happens on cars with effective parts.
same reason why we giggle at street cars with BBKs

The reason for the creation of cross drilled rotors initially was to remove the "gasses" from the brake pads. HOWEVER, most of your modern brake pads (Axxis metal, AEM semi-ceramic) do NOT produce gasses when heating. This was on bad brake pads used in the 1950s and 1960s. Back then, asbestos was also used, and we dont use that either.

also physics 101....braking power comes from friction of pad to rotor....take away surface area what happens?! LESS braking power

Cross drilled rotors have LESS contact area because of the holes.
But if the rotor is cooler, its better, right? Well no, because these rotors are not cooler. THe heat is generated from the pad/rotor contact. What removes heat the most effectively? When stopped or moving, the pad transfers heat into the rotor because its made of cast iron. the rotor has a lot of surface area and even vanes in it. But the little holes allow air in this surface contact, and you can transfer more heat into a solid big ass chunk of cast iron more than you can into the air. Don't believe me? Touch some steam at 150 degrees, then touch a piece of hot metal which is at 150 degrees. Which burns your hand? the metal. So let the heat transfer into the metal, because since it has so much more surface area, dissapates better.

Someone was on honda-tech

I'm with Dan...no it's not an april fools joke. I have C/Ded rotors but only because they came with my car when I bought it.
