Example: Me and my buddy both have BRZ's. I go through pads faster then him. Simple conclusion based on anecdotes? Oh well I must be harder on the brakes or be misdriving them. Conclusion after looking at the data? I'm like 5 seconds faster than him everywhere on track including a way higher V max before each braking zone etc. This. Anecdotal claims are pretty meaningless. Especially with so many variables at play.

What are you talking about? Tokico? The shock company? Lol

It is not well known in the west, but it is a fairly good brake supplier in Japan. Do you have a different information for the BRZ? I thought that the corner was carry over from Wrx (front) and Legacy (rear), and assumed that was Tokico due to that (did not check) But I see that you’re making pretty bold statements from an area that is not your expertise. You are a powertrain engineer, right? How many yrs of experience? PS: doesn’t matter if it was Tokico (yes makes brakes!), Sumitomo, Akebono or Nissin. They would still run JASO, not SAE. And you could ask you friend about the differences on how oems deals with the balance between dyno and vehicle testing. Ask about K2xx vs K2xx PPV, being both from a major manufacturer in Us |

The theory should dictate that its the same heat, and ABS or not does not matter, why would I observe such a bias towards ABS generating more heat? Im not bashing for the sake of bashing, just curious as to why and is there some extra energy that is introduced in the system that is not accounted for here (aside from vehicle speed and mass). |

Force over displacement is work, and that work can only go into heat. That's where the additional heat might come from? The absolute amounts of displacement should be minimal (how much do the pads compress?), but given the high frequency (modern ABS operate at 10+ Hz, IIRC?) and massive overall force, this can be a non-trivial total amount. |

The op is going through brake pads much quicker that we would expect. Decent track pads (almost any brand) are designed for track related braking forces. Many of us are running stock calipers and abs without excessive pad wear. Another way to look at this problem might be to ask, hypothetically, what would you have to do to intentionally ruin a set of pads? Too much left foot braking?

I don't think it's been covered in the 6 pages here but.. Sometimes being slow can be harder on pads.
Before I was "fast", I had braking issues because I braked early and spent too much time on the brake pedal. As I got faster, even though I was converting more speed into the heat, I was spending much less time on the pedal. Less time on the pedal = less heat soak into the system and pad material and more time dissipating heat.

When my car understeered more I was trail braking more and pads didn't last as long.
