More importantly, non-direction vanes promote cracking in deep heat cycling scenarios. The cracks almost always form along a vane. On the other hand, directional vanes add to the structure, and prevent the crack from propagating, as with our rotors, because it has to crack THROUGH the vane in order to continue.

15 days is incredible on a set of pads. I'm getting about 4-6 days out of mine, depending on what pad combo, but mostly at Sebring, which is very hard on brakes.

Hey @Dave-ROR, what are you seeing at Sebring with your AP kit?

I didn't get the mention in my notifications.. but.. I actually have paid less in general for my pads than I did for stock size, but.. I might have a slight hookup there

I cracked one AP rotor before getting as much use out of them as CSG did, however, I was being VERY abusive on the brakes to see if I could actually get fade/failure (I never did - at least I don't consider a crack to be failure. I did however get some serious heat in the calipers and rotors). Pads.. I haven't even used a set up yet.

12 I think? I think I had 8 or 9 on the rotor that cracked but that's wasn't normal.

Wow, that's great. Might have to look into a kit.

And still no issues with the stick rear set up?

The Sprint kit is designed to be used with the stock rear brakes. We haven't had any issues

I know the bias is good, just interesting that you still run out of thermal capacity at the front before the rears fade.

One day, we'll find out... when we're running stickier tires and/or more horsepower. As it sits, there's no way we can ever overwhelm the brakes.

But the brakes are awesome. And the chassis. And the steering.

Agreed, but I drove @thejevans 20 year old Miata with a dead clutch last night...more fun than you can have with a BRZ on the street.

Dude the rears haven't even generated enough heat to bake the paint off the pads yet
