As I posted up above, it looks like David has about 2,200 (or 2,300) track miles.

Fronts are essentially completely worn, while backs are down about a third.
Front replacement cost = $10K/2,200 track miles = $4.55/mile
Rear replacement cost = $10K/6,600 track miles = $1.52/mile
TOTAL = $6.07/track mile (not counting cost of pads)
Yes, there are less expensive refurbishment options available than buying OEM PCCB rotors but, all else being equal, that is still a pretty hefty price tag. Who's done the same calculation using iron brakes?

Sorry guys about the confusion, total track miles: 2350 (26 days). The 511 track miles (6 days) was the difference between the December 2015 and March 2016 measurements.
I know the carbon density measurements are the most important with regard to the PCCBs, but what specifically does them getting to the wear limit mean? Visually they look the same. So at this point are they at higher risk for physically degrading (crumbling/flaking)?

I'm little surprised by the sudden drop in the density measurements. Based on the previous information and the good work of others to calculate the degradation curves I was not expecting to faced with this issue for another 10-20 track days.
Obviously the degradation is not linear.

- Chip the rotor itself (either user error or possibly an errant stone)
- Wear the coating off the surface (this type of degradation is easy to spot).
- Degrade the carbon content of the rotor (not visually apparent but can be determined using the densitometer or by weighing the rotors)

I would try to get a few more days out of it (if you did not noticed any change in the way they feel...)
I started this tread last year but just sold my GT3... RS coming in July.
Even if I'm not tracking the car a lot (7-8 days per year), I'm leaning toward the red calipers this time ... Just dont want to think about my brakes all the time while I enjoy the car on the track!
Still have a few weeks to change my mind (or not)!
