Cayenne turbo brakes!

I like the PF rotors since they're only dimpled which is way less likely to crack than cross-drilled rotors. I only found out after I received them that their hats are not made of aluminum due to lack of strength & restriction in size. I had them coated since they're not coated (bad for winter) as well.

I'll be doing some track with them on stock pads, and provide some feedback.

Great. Thanks, ekam.
I just got off the phone with PF. They said the shipping weight for one of their Boxster S rotors is 22 pounds. The weight of the rotor itself is 18 pounds. I think that four pound difference is the hat, hardware and packaging. For reference, shipping weight of the Zimmerman rotor is 27 pounds.

Losing about six pounds per corner with PF rotors and about nine pounds per corner with OZ Alleggeritas would make a BIG difference.

Whatever rotors I do go with will be used year-round in CO. Can you tell me more about how and why you treated the hats? I would only use the PF rotors if the hats will last many years.

I had them nickel and zinc plated. See link below for the various processes.
