Anyone know what the rear brake rotor size for 2013 Cayenne Turbo is? I know the front is 390mm but can’t confirm the rear size. Dealership can’t confirm either. They said could be 350mm or 360mm.

Depends on what type of brakes (steel or PCCB) and what wheel size.

Rear brake discs:
option 1: 19" wheel with steel --> 358mm x 28 mm

option 2: 19" or 20" wheel with PCCB --> 370 mm x 30 mm.

Since you said your front is 390 mm then you seem to have the 19" wheel, but could be steel or PCCB. 20" wheel front PCCB would be 420 mm x 40 mm (after Nov 2011). Hope this helps - BTW the dealer should know this - give them the VIN and they can verify the correct size.

Ok. The 370 mm x 30 mm is listed as an option on the 2013 turbo for rear. The 358 mm x 28 mm is listed as standard for turbo (330 mm x 28 mm is the rear standard for all other models).

Still, verification by VIN is the best way to go. Good luck.
