That's nothing, i'd run them all day long.

My Alcons look the same... PFC08

Heat soak in the paddock destroys these expendables. It's definitely a balance.
Correct me if i'm wrong, but the cracks indicate irregularities in rotor temps causing it expand/contract causing cracks.

Right on RNH. Ferodo's are great.

I'm glad to see a pattern developing here with rotors wearing faster then we expect and a common link to PFC 08 pads. As much as I love the feel and bite of the 08 pads they are eating through rotors with great fury. I have been replacing pads and rotors at the same pace, which isn't logical at all..

So the problem is less the rotor and more the super aggressive pads. I've just decided to switch over to ferodo pads, too early to comment, but from chats with other track pals all pads seems to be easier than the 08's.

Here is a pic of my recently replaced rotor. Before and after.

agreed, i'd replace the fronts.
why take unnecessary chances? (says the guy who wingsuit bases............)

I was running Pagid RS29 before and they just suck. Long pedal all the time.

PFC08 are amazing but hard on rotors. Which ferodo you running and how do they compare to PFC08?

I am pretty happy with my Hawk DTC 70's, got 12+ days out of them on sticky tires mainly at COTA. Cobalt XR1's are good as well, great initial bite.

I used to run the PFC08 and now the ferodo ds111, you lose a little bit of bite, not much to be honest. I noticed my front pads don't taper as much as the pfc's. The confidence in having a good braking stop after stop is the same and its easier on the rotors.

This was my understanding too. OP those rotors are absolutely not done. I recently replaced my type 3s at a whisker over 32mm with cracking (not to the edge) and the slots were 90% gone. The brakes still worked fine up to that point.




A little disheartening to hear such poor feedback about PFC08 with regards to rotor wear. I have recently tried them from pagids (they felt dead after 50% wear) and like the feel, but at 1K per corner for the brambos, I want some life from them. Does anyone have experience with Race Technologies?

Fwiw the replacement specs I stated are from a friction engineer I know who supports various factory race efforts.

I've had very good luck with the race tech re10 pads several others are using on 991 and gt4. Some like the ferrodo. The RT will last 2x the life. This from the same engineer.
