whassup guys ,,i have been looking around,,and cant find cross drilled rotors for my pepper i checked ebay,,,and the links on this forum any help would be great ,,thank

 

ok guys i found a place ,,its called nights auto ,they are selling zimmerman cross drilled rotors for 550 for bopth front and rear rotors anyone hear of this place ,,and zimmerman is oem rotors for porsche so it shouldn't void any warranties i hope this helps u guys

 

Are they drilled or cast holes?
Be careful with these types of rotors, as they can be prone to cracks forming between the holes. I would not use a rotor once the crack joins 2 adjacent holes......

 

not sure of there cast holes or drilled holes,,how can u tell ?

 

The zimmerman rotors are drilled and not cast. At least that is what they are for the 951 and 944s. I will be replacing mine soon with non holed ones, although they have yet to crack with a number of heavy heavy days a sebring. On the cayenne you should be ok. What do you think ltc?

Probably OK, even given the fact that the Cayenne is a heavy pig, especially when towing.
I've got 56K miles on original brakes WITH towing (don't ask).

Not really sure why you would want drilled/cast hole rotors on a Cayenne, but if you do go that route, I would just make it a habit to check for cracks, or perhaps even send them out for cryo.
Slotted rotors would probably be a bit better of a choice I suppose.

Besides, given your avatar, I'm likely to go along with whatever YOU say

 

Cant drill cay rotors due to vane pattern. I use slotted rotors,

 

Why would you use drilled/slotted rotors on the pepper? Regards. Mike

 

On a 5000# pig, I have no idea.
However, if I were to guess.........

1. They look cool
2. Reduction in unsprung mass aids in steering response.

Tom was correct in going with slotted rotors. I could also see cryo treating the rotors as well.
