I'm looking to get some rotors and pads, but don't know if I have 350mm or 330mm. Does anyone know where on the caliper the 17ZR or 18ZR is located? Photos?

Note: Due to manufacturing differences we have seen, you must determine the size of the rotors on your vehicle prior to ordering. The easiest way to figure out your brake size (other than actually measuring the diameter of your rotors) is to look at the caliper. It should have "17ZR" or "18ZR" cast into the body. 17ZR=330mm, 18ZR=350mm. You can probably see this with the wheel mounted to the vehicle, but you may have to remove the wheel - but it's much less trouble (and cheaper) than returning a set of incorrect rotors/pads.

 

This doesn't really answer your question, but on the '04 S, the fronts are 350x34 and the rears are 330x28. I'm pretty sure this is the same size for all S and Turbos from 2003-2007 (unless you have the turbo power kit). I'm not sure about the base Cayenne. What year and model do you have?

 

No it really does not answer my question. I need to know where the 18zr is cast in the caliper.

04 Cayenne S
w/Silver Calipers

I'm assuming that either the V6 Cayene has the smaller front rotors, or all of them except the Turbo have the smaller rotors.

 

Cayenne V6 = Smaller
Cayenne S and Turbo = Same Calipers and Rotors Just paint difference
Cayenne Turbo S = Total upgrade larger rotors and calipers

 

Hey Guy,I'm having a problem on order the brake pads.My Caliper is red with "18ZR" on the caliper.So it means I need to order the pads for 350mm
Rotor.Is that correct?

 

yes that is correct.

 

He answered your question exactly - 04 Cayenne S takes the 350mm in front.

 

calipers and rotors are not the same on the Cayenne S and Turbo in the 08-09 models are least, bigger everything
