Funny thing my buddy noticed about his Z51 C6 is that he has the exact same "cross-drilled" rotor on both sides of his car, meaning that both the right and left rotor have the same part number. The problem is that they look to be directional fin-wise. He thought Chevy had put the wrong rotor on one side but he verifed with the parts department that indeed the right and left, even though they look to have directional fins, both are listed under the same part number.

And yet I've apparently glowed my boat anchors red. I'm not so sure how much lighter I'd want them. The hat on those things isn't where most of the weight is.

No, no pics, but personally I'll take Tom's word considering the experience and training he has on Porsche cars. I think he probably knows what he's talking about if Porsche uses him as a technical resource on their own cars.

That being said, I have to agree. What difference does it really make. Porsche rotors are track proven to be way better than just about anything else out there. My rotors off my 944 Turbo (16" wheels) are way heavier than the rotors that were on my Z06.

I think there is a general assumption that an Aimco rotor from Autozone has the same metallugy that a Brembo rotor would have.

I doubt it's the case at all ....

From what I've seen on all the GT3R Porsche's and the ALMS things that run...the first thing they do is throw the stock Porsche rotors away. Fine for a hi-po street car....there are better rotors/hats out there for race cars. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif)

There certainly are. The Brembo racing replacements for that application look very nice indeed:

Those teams probably don't mind the nearly $800 per rotor as much as I would though.

That's enough to make me want to find a set of calipers to go with them and drag it all home. Besides, I just got practice installing a set of Porsche brakes this weekend.

I never meant to infer that the new Z06 rotors would be inferior pieces due to being cross-drilled, but it's generally accepted that the cross-drilling is unnecessary. Just eliminates a potential future upgrade path, as this pretty much means blank Z06 rotors are going to be non-existant, and I'm just not going to pay more money for a treatment that doesn't add any value.

actually, $775 each (including hat + rotor)
but then to replace the rotor, it's only $300 each... not too shabby.

Now Now...there are a couple other brake companies out there......AP, Alcon, Brembo, and lets not forget the guys at StopTech. And you can pick up rotors that are just as good as the brembo's for less than 1/2 that cost...just gotta shop around.
