Brakes & Rotors

[FSUKXAZ]

I have a 2004 Porsche Cayenne S. I was looking to find out what rotors would be best for my Cayenne S. The people told me at the brake shop that the OEM rotors are only about average and that I could do better if I wanted to. I was thinking of these 2 types:

- Performance Dimpled & Slotted

- Performance Drilled & Slotted

I drive fast and brake not too hard or soft. I''d say about average. I also want better rotors than what comes on the Cayenne S to begin with. Plus, I don''t want to spend a fortune. So based on all that, what brands would you recommend? And what type of rotor do you recommend? Also what is the difference between 330mm and 350 mm? What is supposed to be on my vehicle? Any experiences you could share may also be helpful.

Thank you,

Todd

I put Zimmerman drilled rotors with Hawk HBS dustless pads, they work fine for me and I am about the same as your driving habits. Clean wheels are a great plus

Where can u get those rotors and pads? how much r they?

You must determine the size of the rotors on your vehicle prior to ordering. The easiest way to figure out your brake size is to look at the caliper. It should have "17ZR" or "18ZR" cast into the body. 17ZR=330mm (black caliper), 18ZR=350mm (silver and red caliper). In general the V6 has the 330mm rotors and the V8 has the 350mm rotors.

Second, OEM rotors are made by Zimmerman. Don't buy them from Porsche, you can find them cheaper on the web. Here is a link: http://www.pap-parts.com/products.asp?dept=4129

Make sure you get the rotor removal bit first. The front uses a Torx-50. I'm still looking for what the rear uses (it's different...thanks Porsche). If anyone knows, please let me know.

I have the silver caliper, but i was told by Just Brakes that I needed the 330mm. So ???. I'll look at the calipers like you suggested this afternoon and verify that they are 350mm. I have the Cayenne S model which means the V8 so I would assume it's 350mm. So besides Zimmerman who else would you recommend?

BTW - Thank you, it's nice to talk to another Cayenne owner who knows what I'm going through.

So my thinking was that I wanted to stay with OEM, since I assume Porshe has poured tons of manpower into choosing the best for their lineup (it's the same on all cars so I'm told...including carrera). They use Pagid pads and Zimmerman rotors. You may find others who have track experience that will give you track recomendations. I didn't go this route. I did just replace my rotors this weekend after doing a full brake job on the front. I have a Cayenne S and got the following from autohausaz for $413:

1 7L0698151J Brake Pad Set; Front; OE Compound

2 7L0907637 Brake Pad Wear Sensor; Front Left/Right

1 7L6615301K Brake Disc/Brake Rotor, Directional; Front Left; Vented 350x34mm

1 7L6615302K Brake Disc/Brake Rotor, Directional; Front Right; Vented 350x34mm

Much like you, I had to first check if the rotors were 17" (330) or 18" (350) and this was identified on the top of the caliper. You also need to buy the caliper removal bit (front was a torx-50). In hindsight I should have also replaced the caliper bolts because I had to tear up the bolt to get it off (it's 200lb tourqe). I didn't want to replace the rotors but I bought a caliper tool and I had 28% left after 33K miles. This wouldn't have lasted another pad set.

V8 Brake disc thickness, new

front - 34 mm

rear - 28 mm

Brake discs minimum thickness

front - 32 mm

rear - 26 mm

For the Cayenne V6 Brake disc thickness, new

front - 32 mm

rear - 28 mm

Brake discs minimum thickness

front - 30 mm

rear - 26 mm

Does anyone have detailed directions on the replacement of the rotors including the removal of the caliper obviously.
