BTW the new ZO6, Ford GT and Ford Shelby Cobra all use the same PN rotor right and left sides....
If you still don't want to use them I understand, and that's what makes the world go 'round.....
Enjoy, Pat

It does not matter either, drilled or cast, Camferd holes or not, rotors with holes in will crack sooner then latter.
For street driving you will never notice the difference, for road racing or track day DEs, it is only a matter of HOURS before the cracks start.

I havn't found any cheap Z51 rotors for racing or street use... but I have it on good authority that Stop Force (www.stopforce.com) is applying for a patent on a Porsche rotor in Z51 specs.... should be released soon from what I was told.
Soon every C5 and C6 (and any other vehicle with C5 adapted brakes... like high hp Trans Am's and Z28's
) will be able to swap in rotors/brackets for an easy upgrade to directional SETS of larger rotors.
Hopefully someone will start making some cheap directional blanks as well... not everyone can afford $600 rotors!

Sounds good steve. at least the stopforce rotors use porsche parts with aluminum hats.(they shouldn't crack) Sounds like they would be good for the z51. They would make good street rotors for me, but I dont have that kind of money to be destroying them on track days. Cheap blanks would be nice too.
