And the slot's/holes are for venting gas, as an earlier post stated, and in no way cools the rotors, other than releasing hot gases.

 

Anothe quote from the Z06vette.com thread....

 

are the ford GT's rotors the same part# on each side? they might have only had one drill press but the internal vanes are different.

 

I just checked out pictures of the GT and sure enough, it's the same rotor on both sides.....at least in their official pictures it is.

 

Wow. This is sad for both Ford and Chevy.

 

Don't forget Mercedes Benz too...

Seems like all of their engineers are satisfied with the one rotor....and all of us "internet engineers" might just not understand their view of the cost vs benefit ratio.

I find it odd that the C6 Z06 rotors are even stamped LEFT though......

 

but are the vanes on the inside of the ford and mercedes the correct way or are they the exact same part number for each side?

 

Can't say for sure, but knowing how and where the holes need to be drilled (or cast) they indicate the vane direction.

 

But it still makes no sense to make a directional rotor and only make the left one. Why not straight vanes if you want the same part for both sides?

It seems like they all cheaped out. Someone outside engineering had to kill the right rotor in all of the cases.

 

Somehow I doubt theres any scientific data that actually shows one rotor working so much worse because it faces the wrong way then the other one on these cars.
I am sure at least one of the 3 cars already named in the thread got extensive testing. In reality all 3. I can almost guarentee that there is no noticiable difference in the way one side stops over the other.
I agree with the porsche engineers here thats it's all marketing perception and people think its great because aftermarket manufactors tell us it is and we buy their expensive stuff and no one wants to believe they are wasting their money.

I think this thread is suffering from ricer syndrome. The most expensive, most shineyest, most hyped part has to be the best because umm it does and we all know the 5 inch tip is better then the 4 inch chrome tip which is better then the 4 inch matte finish tip, which is better then the 3 inch HKS tip which is better then the 3 inch generic tip, when in reality it's all a marketing perception and the car can't perform past the limits of any of the tips, so it doesn't really matter.

 

Actually my definition of rice is when parts are on a car for the appearance of performance but they don't actually function.

The bastardized brake rotors would fit into that category. Somehow I don't think a properly designed and functioning set of 14" 6 piston brakes is "rice".

 

Man, I'm glad you told me that. I've been driving my Camaro on snow tires with race compound pads on it for the last few winters and am currently doing it right now. If I'd known that, I'd have surely killed myself by now.....

Actually, other than the noise and dust, they work good to great on the street, even in the cold.

Some friends at the 12 hours of Summit Point in 2005 were running a BMW M3 and accidentally got two matching rotors on the front (two lefts or two rights, I forget which). When they pitted, one set of pads was "junk" (cracked, extremely worn, etc) and the rotor on that side was cracked and discolored by heat (it appeared to have been much hotter than the opposite side, one rotor was a little blue, one was purple/black). So, that seems to indicate that the rotor direction does, or can, matter. These were Performance Friction rotor rings on an AP "strap rotor" floating hat assembly.

But, this was a "full out race car" (as you stated).

 

You are an idiot. Thanks for playing.

 

BUT, you're an experienced driver who knows how to drive on race pads...I've done it too.....but I wouldn't sell a car to who knows who and not expect to get sued for them smacking into something....

There are always compromises made for production cars that will see 90% of their life on the street.

What is acceptable dust, noise and cold pads to you are certianly not acceptable to a majority of the Corvette owners (PITA's that they are).

But there again, this was in hardcore race conditions...not everyday spirited street driving.

 

Lose the attitude...no need for that here........
