So far, all the pics that I've seen that show the rotors, showed cross drilled rotors. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/mad.gif)
Correct me if I'm wrong, but the C5 Z06 still used solid rotors? |

You're right. C5 used solid rotors.
"Everybody is doing it, so why don't we" seems to be the reason behind the new Z06 and the "pretty" rotors. |

Whatever. If you can afford to buy a new ZO6, you can probably afford some new rotors. Maybe it'll help them sell a few more cars.

(IMG:http://www.frrax.com/rrforum/style_emoticons/default/tongue.gif) It's just cheap to sell out to stuff like that.

The base model C6 with the Z51??? package has cross drilled rotors. We just received one at work a few weeks ago.
Not actually cross drilled by casted it appears. |

I don't see why you guys are SO against cross drilling.
There is no Selling out going on here. I guess porsche and Ferrari "sold out" eh? |

Louis, almost EVERY business out there technically "sells out". That's the whole point, give the customer what they want. Don't believe for one second that there is a single automobile manufacturer out there that hasn't made a change to their models lines not because it truly made it a better car, but because it made the customer perceive it as a better car.
In any type of consumer environment, regardless what level you're selling at, perception is reality. Simple as that. |

The rotors on the new Z and the Z51 C6 look like quality pieces. They have the same fit and finish as a brembo piece. I know a few delphi engineers that worked on the brake system for these cars and if there was a compromise, it would not have been put on the car.
I will let you know how they hold up in testing (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif) |

Porsche and Ferrari use rotors that have the holes cast into them when they are made, not cross drilled later. I can't speak to the new C6Z51/Z06 rotors on that. I do know, that even Porsche for a while used blank rotors on it's top line performance cars. My 88 944 Turbo S has blank rotors, while the base 944 Turbos came with "cross drilled" (cast) rotors. The reason? Porsche knew way back then that rotors with holes in them are really just for appearance. The only reason most Porsches and Ferraris today come with rotors with "cross drilled" holes is because the customer expects it, not because of any performance gains. Unfortunately it looks like GM is taking the same route. Personally, if they are going to use "cross drilled" rotors, I would prefer to see them on the base C6 and use "blank" rotors on the performance models (Z51/Z06).

We've been trying very hard to prove that statement to be correct. So far, no luck. It is looking more and more like a myth/marketing hype. http://corner-carvers.com/forums/showthrea...ead.php?t=21273 |

I for one am willing to consider this is a different class of rotor than the usual dearth that has holes in it available for our cars.

Ok, let me solve the Porsche rotor question once and for all. I just got off the phone with Tom Charlesworth, who is one of the most recognised Porsche mechanics in the US (as well as being on the PCA tech commity and answering technical support for Porsche North America on 924/944/968 cars). He is Porsche trained and has been involved with Porsche racing efforst, so I think we can trust his answer on this.
His statement is: FACTORY Porsche cross drilled rotors have pilot holes cast in, but then are machined to finish them off after casting. Kevin, I'll let you post this on to cornercarvers as I don't have an account there. |

...who REALLY cares????
Porsche brakes are pretty much PROVEN day in/day out....and a few weekends a year on my car in SCCA competition... (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif) I think it is safe to assume that for the Z06, GM did the brakes "right".....time will tell... |

How about pics of the machine used to drill the rotors after casting? :leaving: Just playing devils advocate... |
