AutoZone rotors are $38 each and work great. You can reuse your stock pads.

Common problem, sounds like warped rotors. I have this problem too and just bought Autozone rotors today. Very cheap, $38 each and $83 for both and tax. I think the pads should be replaced to, but I don't know. I'm gonna put them on tomarrow and I'll let you know how they work.

I also heard very good things about the AutoZone rotors. I already got the pads from them ($30) and was going to replace them... then I had a closer look at the rotors and decided to replace them too. For that price it's a good idea to change rotors and pads, it's 110 bucks all together...

AutoZone... *shakes head*

Don't you people realize that brake rotors effect pad wear, noise as well as stopping distance? I see all these nice cars in the signatures, and yet so many want cheapo rotors. And brake pads have an even more dramatic affect on stopping distance. 15 ft. can easily be the difference between hitting some moron that pulls out in front of you, and saving your car. Even if insurance covers it, personally I would preffer not to wreck my Z28. These cars are made not only to go fast and handle well, but stop good too.

Oh well, just my $.02.

Rotors do not affect stopping distance. They are iron, which all has about the same coefficent of friction. Pads make the difference.


Here is a video of me totally outbraking a 911 Carrera and a couple other Porsches on a road course, and I had AutoZone rotors:

Rotors are not all the same.

The type of finish cut affects stopping distance shown here
While new rotors may not use this method, it shows that it does make a difference


This link shows how rotor thickness and weight can affect stopping distance by reducing fade

The number of vanes and vane configuration affects rotor cooling, and keeping the rotor cooler helps reduce brake fade and stopping distance.

As for they are all made of iron, some are cast and some are composite, they are not all made from the same pot of metal

This link shows some of the design features on rotors that are not all the same.

As for you out-braking the others in that video you don't know how hard they were stopping. And you where not next to them so you can't compare how fast you slowed down.

Just a few links I found on a quick search that show brake rotors do affect how a car stops. And as I said before, pads make more of a difference, but rotors affect how long pads last and how hot they get(affecting brake fade).

Guess this makes $.04

Chuck, you notice I quit argueing with folks about this and how an STB affects handling.

All you can do is let folks know how we have PERSONALLY abused the crap out of AZ rotors and they have held up amazingly well.

If these guys want to spend $100/rotor as opposed to $38/rotor, then there is more disposable income out there than I and probably you have.
