I realize that conventional wisdom is that CCBs don't hold up to track use, but in the recent tech talk with Brembo they seemed pretty confident in the brakes on the 5BW. I thought I'd start a thread to track how my CCB brakes are holding up to track use.
My car currently has 8390 miles and 6.34 hours of track time on it - mostly VIR and Summit Point main. I run at an advanced pace and don't go on track without the PDR running. I have a macro in Pi Toolbox that populates an Excel spreadsheet with data like session miles, duration, best lap time, etc.
Stock pads are just under 15mm in total thickness with 6.7 mm of backing plate, so you're looking at ~7mm of usable pad material.
My rear pads are the original set on the car and currently measure 12mm total thickness.
I've run two sets of front pads, my first set I replaced after 2.6 hours because I assumed they wouldn't last another 3 days at VIR and had heard not to run CCB pads below half thickness or it'll accelerate rotor wear. In retrospect, that was wrong as confirmed with the Brembo engineer who said to run them until the pad wear sensor comes on and you get to the last ~2mm of pad. Luckily I still have the pads and will put them back on, that set is currently 12mm total thickness.
The second set of front pads have 3.75 hours on them and are also around 12mm thick. This set just had VIR track time on it, whereas the prior set had a bunch of Summit Point time, so that could explain the wear difference.
The real question is how the rotor is going to be and I don't have an answer on that at this point. The rotors looks great, and measuring them with a rotor caliper shows them ~0.6mm above the minimum thickness stamped on the rotor. I have no idea what the new thickness is relative to min, so I can't use that to judge wear.
I share all this to give some data to those of you looking to buy a 5BW and track it. So far, I'll say that I am really impressed with how long the pads are lasting and how well they work. Time will tell on the rotors, and truthfully, I hope I don't have to pay for a new set.

The 5BW really is an incredible machine, but it isn't my primary track car. Lightning lap uses the Grand Course which really mutes the power advantage and also favors lighter more nimble cars.
