2009 Cayenne Turbo/Turbo S rotor wear...lipping?
I’m trying to sell my 2009 CTT w/ 45,555 miles. I was told that my rotors have “lipping”. This is where the Turbo S comes in...my Cayenne Turbo is fitted with the ginormous (thanks Elf - movie reference) 380mm front calipers, and standard backs. Those are unusually expensive to replace.
The brake pads all around were replaced by non Porsche dealership that I purchased the car from about 1200 miles ago, earlier this year. That guy said the rotors were within specs. It seems from my research that with new pads and rotors in specs, the brakes should last a decent length of time. The guy is saying he’s taking $2-3k off my price because of that (his prerogative of course) and I disagree, because they are normal functioning now and with new pads, no squeaks or alarms and feeling nice and tight when driving they should be good for a long while yet.
Opinions? Thanks

Looks like you got some fancy 2 piece rotors. Factory replacements are indeed 2K$ for 2 rotors. I own S with 150K on the clock - rotors have lips and I will need a new (probably 3rd) set of brakes pads soon. Dealer just checked it out and I am looking at printout: thickness is 30.80 with the limit being 32.00.
Your rotors are indeed 2k$ to replace - https://www.ecstuning.com/b-genuine-...95535140161kt/
So presence of lip is normal wear, but you need to measure thinkness of rotor to see how much life you got left - i'd say you about 50% Normaly rotors last 2 sets of pad - when you bought it - they probably put the second set on factory rotors - next pad replacement - is both pads and rotors.

This is a subjective thing and there are a lot of owners who have been brainwashed since there are Porsche stealerships all over the country who try to force new rotors with every set of pads. The only way to officially decide if the rotors are in need of replacement right now is to measure if the thickness is within the published spec.
Judging by the number of miles on the vehicle, your description, pictures, etc. I think the rotors are fine, but should replaced on the next set of new pads. The general rule of thumb that I follow if not tracking the vehicle is 2 sets of pads per rotor.

For what it's worth...my brakes were in the same situation when I tried buying my ctts. The PPI and a visit to the sellers dealer revealed that the brakes (which looked identical to yours) had only 10% left. As a new buyer being saddled with a 3k bill it didn't sit well and ultimately the seller gave a 2500 concession for me to resolve the issue after purchase. It still cost me 3300 including labor but I felt it was fair.
It's also worth mentioning that 40-50k seems to be the life on these rotors at most.
Crazy that you have the ctts brakes....not sure why anyone would sign up for them willingly!

Minimum rotor thickness will be written right on the rotor. Maybe offer to split the cost with him if they measure close to the wear limit, but still have life left.

One thing odd is that I just had the tires done at the Porsche Dealership, and what respectable Porsche dealership would change the tires and not try to get me to go for brake job if the brakes were anywhere close to needing done? Ha ha!
I like the idea of halvsies with the purchaser. Seems fair, but of course every ding against this beautiful CTT example lowers the price on my end. I may be a fool to let it go...but stomaching such extreme loss of cash is the part of Porsche ownership that I just don’t think I can tolerate anymore, but I’ll have to in order to move on.
Thanks again for the helpful ideas and insights.

You can get the parts for all 4 brakes for less than 2k and change them yourself. How many miles on the rotors? Autohaus AZ has the front rotors for about $550/piece. Or since you have the CTT, why not just replace with the factory size rotors and save a bundle???

The calipers and rotors need to match. If he's running the 380mm rotors, then its likely the PO upgraded from the Turbo setup to the Turbo S setup or he had brackets made to move the calipers further out yo work with the larger rotors. You can't just go back to the original diameter rotor without also going back to the original caliper and pads or the swept area of the pads on the rotors won't work correctly.
