You don't want the Z06 rotors, they are junk.

??? Why! Why!! Why!!! I need to know why!!!!

if you read whats in teh link that I provided on the first page, you would know. You seem to be too busy defending yourself instead of listening.

I find this funny, on a differnet forum, I find you giving peope this advice, sounds just like what we are telling you, but for some reason you don't like hearing it.

Just a question? What is the most powerful car you have driven or been in?? 1000 hp is NOT childs play. It may sound like a nice easy roung number, but that is serious power. I rarely ever use my power. On the street I only use about 700 hp of it tops! Even 700 hp is hard to control, I would sure hate to always have to worry about shifting not to mention that you will ALWAYS be spinning the tires and shifting in the middle of a controlled slide could be a little dangerous!! .......
I am not trying to shoot you down in any way, I am just offering the best advice I can give to make your life a little easier and cheaper."

But you do have a legitimate question, and IMO you have recieved a TON of good info on both your brake/suspension and some really good info on trackdays etc. Hey you must already know everything, I mean even if every single person posting on this thread says the same thing, hey who cares, thats not the info you asked for, right?

oh and heres what my tire looked like after 3 trackdays and was toast; so be prepared to start spending money on tires if you want to go fast

:D :D

go c5 calipers with z-51 front rotors (13-3/8) do not use the zo6 14 inch rotors for one have fun making it work and two they weigh like 26 lbs or something

probably won't fit with his 17" wheels, and plus the problem with the Z51 rotors is the same as the Z06 which is the fact you can only get 2 left hand side rotors. The right side is not going to cool very well due too the vents being faced backwards. Plus they are crossdrilled. THey should be good for a street car, but for a track where you see 150mph repeadetly I would stay away from them. Actually I would stay away from them for any track time. 6, 20 minute sessions in one day will toast an inadequate rotor if you are pushing it at all.

What does a c5 rotor weight?? From what I have actually found, the new Zo6 brake problem seems to be the calipers??

i agree about the cross drilled but, but i highly doubt vettes are the only ones that use the same rotor left and right, lets see some proof that a non cross drilled rotor will not work well for a non race car doing some track days.
wheres carlc or the orange crush dude

What are you talking about? Of course a non cross drilled rotor will work fine???? And neither of those guys are running 2 left hand side rotors. That is the prob, way worse than crossdrilling. If you look at some rotors, the vanes inbetween the pad surfaces are sometimes just straight, meaning that you can use them on either the left or the right. The don't cool as great as directional rotors, but they still work. Then look at some other rotors, such as C5's. They are directional, they have a left and a right hand side rotor. The vanes are directional on these, they curve backwards to hellp direct air inbetween the rotor to cool it down. Now for some reason GM decided to skimp and use 2 of the same side rotor. So now the right hand side rotor's vanes are facing foward, which is now competely opposite of what of the rotor is supposed to have. All of the vette guys complained about this.

The Z06 and the Z51 both have this. Its possible you might get by with it, but why? just to get an extra .5" i diameter?? Not worth it IMO, especially for a track like RA where you will be repeatedly braking at 150mph. Stupidist thing GM did to cut costs
