I posted this over on the Rennlist too but thought I would spread the love just in case some of you aren't on there. I hope the site doesn't present this all in 1 long run-on sentence or it may be even more confusing. Cheers.

I've googled every way I can think of and looked over the Porsche literature on line and in print and can't find consistent info on the different brake sizes.

Plus Porsche says or prints contradictory specifications. Printed vs online vs spoken when you click on info or different specifications in different places in print vs spoken by salesmen. Additionally I don't know if anything has changed for 2014.

What I have so far:

PCCB Brakes. Turbo Turbo S GTS? F. 416.5mm (16.4") R. 370mm
Also listed in Porsche literature. F. 410mm R. 370mm
Other models GTS? F. 390mm R. 370mm

Turbo S. F. 390mm R. 358mm

Turbo and GTS? F. 360mm R. 330mm I think. But I'm not sure as the only data I can find is from a few years old and I don't know if they have changed anything. Plus my dealer told be the GTS has the same brakes as the Turbo and they are Red like the Turbo's. On the website Porsche says the GTS has the same brakes as the Cayenne S model. The dealer says a GTS is the same in every way as a Turbo except for the turbo system itself.

Cayenne. F. 350mm R. 330mm

Cayenne S. GTS? F. 360mm R. 330mm

Does anyone have a real world handle on all of this?

 

350, 360, 390 and 410 are the 4 different rotor sizes listed. I don't have accurate info as to which is which.
