Default Drilled vs Slotted Rotors and Pad Wear

So someone told me that the OEM drilled C6Z06 rotors will eat pads compared to a slotted like the DBA.

Any truth to this.

I run both and not sure about it

Worse than eating pads, the drilled ones will crack around the holes and eventually split the rotor from uneven cooling. get the slotted, DBR, Zeckhausen, others.

My feeling is that if drilled is so good all the race teams would have them, look at the C5R & C6R, even the GT2 steel rotors....not drilled.

Thanks, but I'm not concerned about the cracking problem. I have used both for the last 5 years and cracked both. I monitor and replace as necessary.

I just want to know if I am wasting away good pad by using the drilled rotor.

Yes you are.
They're like cheese graters.
Holes are for bite and more bite means more friction.
Pads back in the '70s required holes for good bite, pads today have plenty of bite, so the holes are not needed.
That's why you won't find them on professional race cars.

Using DTC70 pads so bite is not an issue.

Drilled rotors are a cosmetic item. They don't belong on a serious car.

I guess you didn't understand the solution.
You don't need holes, WHY, because bite isn't an issue.
So, in reality, you're scraping off pad material that is wasted.
If I have to explain it to in any more detail, I'll have to charge you!

Another brake rotor article. If the article doesn't come up look over at the left hand column for the article.

Holes were for outgassing of asbestos gasses from asbestos brake pads in the 1970s. Nothing to do with bit.

so the holes are not needed.

Correct

Holes are purely a cosmetic through back to the 1970s

Brake ****

I now know what it's like to use all of the brakes. I didn't touch the brakes until I saw God. Amazingly the car slowed down enough to take the turn and put me back on the front straight intact. I discovered the reason I'm not a professional driver. They can do that lap after lap. It took me until turn 2 to realize I was still alive.


Trying to get here on T1 of my local track.

Let's answer the question

WHAT DO YOU RUN ON YOUR CORVETTE
DRILLED OR SLOTTED


DRILLED ROTORS WERE ORIGINALLY INTENDED FOR BITE AND IT DOUBLED FOR OFF GASSING. NOW FOR 40 YEARS THAT WASN'T AN ISSUE.

That's a good looking rotor. I like the blank or "flat face" rotors from http://shop.performanceafx.com/C6-Corvette_c11.htm
