I had some free time today so I changed the oil in my car and inspected the brakes......and emptied the garage of all beer.
Jenk12M......for you I included a picture of a real nice flag and national championship banner.... LOL![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
Took some notes if you are interested.
I just flipped the fronts since they were tapered and will continue using the pads until they hit the backing plate. I really want to see how much I can get out of them
The tracks and mileages are below, I drove the car with stability control and traction control on the entire trip
Autobahn / 190 miles
Road America / 280 miles
Mosport / 150 miles
Mid Ohio / 250 miles
Watkins Glen / 211 miles
If I remember correct new pads are 18 mm front and 17.5 mm rear (I will check this)
Left Front Inner
Top / 14.32 mm
Bottom / 10.72 mm
Left Front Outer
Top / 13.82 mm
Bottom / 11.65 mm
Right Front Inner
Top / 14.06 mm
Bottom / 11.1 mm
Right Front Outer

Hey Izzone, is that a spring depressor in the background? If so, where do you guys get them and how well do they work?
Also, how streetable are these pads for a street/ track car. Do they have enough stopping power when cold to be used safely?

they have plenty of live left if you can actually use them down to the backing plate.
PLEASE TAKE THE BANNER DOWN OR I WILL DO IT FOR YOU! j/k

I will post pad measurements later today.
I had one day Sebring and one day Homestead followed by the same 6 first days as Izzone.
After that, we changed all and did the same 4 last days as Izzone. Could measure them now but the car is at Orbit. I will try to put a new set in before Sebring and run straight Sebring untill I run out of pads.
I think they are fine on the street. Just like Pagid and a bit less squeel.

My electronic sliding thingy is out of batteries, so with a ruler:
Rears all 13-14mm.
They start at 19mm and the backing plate is 5mm, so 14mm of material at start, after 8 days 5-6mm material used, 8/9mm left, no tapering. So should be good for another 8 days in theory.
Fronts between 7 and 11 mm left.
After 8 days 12-8 mm material used, 2/6 mm left, some tapering, but not enough to flip.
Seems I will get an easy 6 days evan at Sebring and more if not all 6 days are brake killing tracks like Sebring, etc.
My rear brake wear seems identical after 8 days compared to 10 days on Izzones, but the fronts were worn much more after 8 days compared to Izzone's 10.
Part of that would be explained by me first 2 days being Sebring and Homestead, but then why the same brake wear in the rear. Could be more TC and SC use on Izzone's car, my LSD or a combination of both..
I have definately been hard on the brakes, overslowing for corners while learning all the new tracks.
And I have extra front brake cooling that Izzone's car does not have. Who knows how much that helps.
I will keep testing

Trakcar and Izzone....how does the "feel" of the PFC pads differ from Pagid and Endless?....hearing that both Pagid and Endless have that same mushy feeling.

That is awesome wear rates. I have been running Cobalt XR2's on the 6GT3 with very good results 6 days and a lot left but don't have any measurements to go by.

Went to Sebring yesterday with Chin motorsports.
Same brake pads I started with before manication. as shown above, flipped them when I put them back in.
Figued the best test would be mid August at Sebring. I stayed out for teh entire "happy hour", this was almost an hour of time at 4pm in heat. The above video is the past laps of the session.
I could not get the pads to fade. The pedal traveled a little bit, but never even close to the height of the gas pedal like endless used to.
A quick inspection shows I still have pad material left, plan on running them to the backing plate
