Factory brake cooling ducts/guides?
Yeah, sounds like the same crap. So I had both front rotors turned on a lathe, and there appears to be some difference in metals now on both front rotors. I'm running Ferodo DS3000's, so I figure I'm going got swap in these rotors on track days, and not have multiple compounds ever come into contact with the rotors and hopefully fix another braking issue.
I read up in the Motorsports forum: not a lot of positive reviews on these.
I instead went with the Forged Performance ducting kit, and mated them to Ferodo DS2500s all around. Even with the ducting, I was getting a bit of fade, so I switched to DTC60s in the front: problem solved. I'm running ~320whp, and 255/40 AD08s.
bottom line, I don't think you'll see significant advantage from going with the guides, at HPDE.

Matches my experience. And overheated DS2500's do tend to transfer unevenly causing big time shuddering. I switched to Pagid RS29, but these did not clean up the rotors enough so I got new 2-piece rotors. Problem $olved.
DS3000's are notorious for pad transfer and uneven deposits..... boo.
I'd run Hawk DTC-60 or Raybestos ST43's for track pads. I love me some ST43's.... After 4 track days they still look nearly new in terms of wear.

That's what's got me so burned, these are on BRAND NEW blanks. How do you prevent the pad transfer? I followed the brake in procedure every time I swap pads for track days.
thinking about going to the oct 10 track day in oregon with GTisRule but not so sure after hearing the news on the ferodo 2500s. that is what i'm running. I need to make sure i can get back safely to seattle.
You're not changing pad compounds though, I think that's where my problem came from.
Pad transfer seems to be a characteristic of certain pads when over heated, some are worse than others. The Ferodo DS3000's seem to be a bad one.
I never had problems with my DS2500's, but I always ran ducting with them and mostly on street tires.

From: somewhere testing various tires, brakes, and suspensions.
I wrote a massive thread on pads/ducts/rotors/etc in the Wheel/Tire Forum. DS2500s are not track pads, MOT of 1000F is pretty easy to run up to on the heavy Evo.
+1. I went from OEM --> HPS+ --> DS2500s ---> DTC60 front / DS2500 rear.
I'm not running high horsepower, or R compounds, either... and I have the Forged ducting kit to keep things cool.
I thought I could get away with the DS2500s as a street/HPDE compromise (especially with the ducting kit), but no dice.
Finally happy with my setup, although it took 4 iterations to get there. No pad transfer, no fade, just strong reliable braking.
