Ok so I called Carbotech to talk to to a rep about their 1521 series brake pad which seems to to have a lot of satisfied drivers. Anyways upon talking with him he was able to tell me that the heat resistance for these pads is 800 degrees with minimal dust and are also quiet. He also suggested that our stock OE pads have a heat resistance of only 500 degrees. So I would like to ask does anyone know or know where to look so that we can see what the heat resistance is for our OE pads. If not, maybe where to contact so to inquire. Id be happy to do so and share it for others. I think it would be interesting to know for a fact what is the heat resistance of our OE pads. This way when you go to buy you a have an aspect to keep in mind and you can know if you are staying even or increasing capability.

Not really an issue for street driving. When you go to race pads the max operating temp goes way up and ranges between ~ 1300 and 1600 degrees depending on compound and manufacturer. However, if you are interested in the 1521 pads you definitely won't be interested in the race compounds since they will cover your wheels with pad and rotor dust within a mile or two and will squeal loud and painfully enough to wake the dead.

The stock pads could be 500 degrees or 800. It really doesn't matter.

Are you going to be tracking the car?

Titanium brake shims will help with heat transfer.

Not really!!! Here's a picture of the stock pads for a C7 Z06 or GS with cast iron rotors:




You can see "Ferodo HP1000/1" which is the compound used on the OE pads. I haven't been able to find any specs for that compound, however there's also an "FF" after the pad compound. Take a look at this post (and the whole thread) where we have discussed this in the past in the AutoX/Roadrace section of the forum. The "FF" indicates that fade is possible at 600°F:

The Carbotech 1521 has a max operating temp of 800°F (426°C).

Take a look at this Carbotech site with temp operating zones for their various compounds:

So....the OE pad max temp is not suitable for track use, and it probably has a lower operating temp range than the 1521 before you'll lose the brakes from pad fade. Even with a slightly higher max operating temp, the Carbotech website says: "Carbotech™ 1521™ is NOT recommended for ANY track use."

My first day out, I overheated my brakes almost instantly. My buddy with a Z06 did the same in his with Stoptech pads.

I was in Sport 1 and he was in just basic track mode (didn't know about the others). I was very disappointed.

Once I switched over to Sport 2 and Race I didn't really have any problems, but I was still nervous. I'm a pretty decent driver at this track and the track is hell on brakes.

No chance I'd try it with cup2 tires or a Z06 btw.


So if you think you can handle the car in sport 2 (or race) and are on PSS tires, you should be okay. Kind of stupid to risk it though. My pads just didn't arrive in time.

Also, if you're on the street, factory pads are way more than adequate.
