I do not agree. That article is relevant to a test car, not a race car or track driven car. Brake usage on street cars, no matter how hard you try, can not even approach to use on track.
175,000 track miles? Where? Who? Certainly not the PDE cars. That would be an astonishing achievement, and clearly not backed up by the other article by Christophorous citing rotor replacement on cup cars. Certainly cup cars see nowhere near 175k miles, let along even 20,000 miles.
I have no axe to grind, was a prior PCCB owner, may be again, but I'd prefer to have the facts out there rather than repeated intnet lore.
Even if what I was told by my own Porsche sales rep about 175,000 PDA miles showing .01mm wear was incorrect I think the article you posted showing NO WEAR on a 175,000 test car speaks volumes. That info. is good info. for me. NO WEAR at 175,000 miles so how many miles can you drive before needing a rotor replacement? 275,000? 300,000? And I bet THEIR 175,000 miles is a lot harsher on brakes then my own miles.
But just to be thorough because I agree that internet lore sucks I've emailed the rep to ask for back-up. Here's his original email which you have to admit is very believable after you read the article you posted:
" Steel rotors are cheap $1000, three different part numbers
997-351-405-00
997-351-406-00
997-352-405-01
Ceramic rotors are cost $$arm and $$leg sometimes $$firstborn too
I don't have exact pricing yet and parts are going to get back to me with
that but in testing the CERAMIC ROTORS after 300,000 miles showed VIRTUALLY
NO WEAR. At PDE (Porsche Driving Experience) in RACE ONLY cars, with
175,000 RACE MILES and RACE BRAKING...showed less than .01mm wear at the
rotor. You'll never need replacement of a rotor unless you plan on driving
to the moon. This is a worthwhile option because not only does the car
brake better, but the car handles better because of unsprung weight.
Literally you can brake so late into corners and on the street it is safer
because of the shorter stopping distance and resistance to fade...MOST
IMPORTANT, NO BRAKE DUST!!! Am I doing a good job selling this option yet?
When you get standard brakes, when you do pads, they will suggest rotor
changes as well making pad replacement much more expensive in the
$2300-$2400 range. After a few brake jobs you've recouped your money! :-)
Anyway, I would MAKE YOU UPGRADE CARS BEFORE YOU EVEN WOULD NEED A BRAKE
CHANGE!"
Point being I wont ever need PCCB rotor replacement.......The guy I sell my turbo to in 5 or 6 or 7 years from now probably wont need PCCB rotor replacement and the guy he sells the car to probably wont need rotor replacement.
