All replacement rotors match the OEM requirements; some skimp on vane configuration to make one-size-fits-all rotors for many makes and models. The better ones mimic the vane configuration of the OEM rotors.I did a search and wasn't able to find a result I was happy with.
I am looking for feedback on rotors made by Rotora, and Carbotech.
Do they improve dissipation in turn improving braking, or is it placebo, and i should return to OEM?
just out of curiosity, who was the other D3EA certified company.?All replacement rotors match the OEM requirements; some skimp on vane configuration to make one-size-fits-all rotors for many makes and models. The better ones mimic the vane configuration of the OEM rotors.
To my knowledge, only two among the many replacement rotors available for the Mazda6 are D3EA certified. I have researched the options pretty thoroughly, and my money went for the Raybestos PG Plus. http://www.raybestos.com/usa/products.htm
Good rule to keep in mind: when purchasing anything, the company that makes nothing but the product you are looking for is a good bet. (For instance, Plextor CD/DVD disk drives for computers have to be good, because Plextor makes nothing else: if they are bad, the company goes down. But if, say, a Mitsubishi drive is bad, Mitsubishi can make up the difference by selling something else.) Raybestos specializes in automotive friction materials, does nothing else. They have been in business for years, and are very good at what they do. [/b]
Official websiteWhat does the certification require?
Price is a good place to start. You can find a pair of front Raybestos rotors for the Mazda6 for under $100.meaning why is it better to buy Raybestos...vrs Carbotech aside from the certification?
I don't know who the OEM supplier of the Mazda6 rotors is. Rumor has it that Mazda subcontracted the design of the Mazda6's braking subsystem to Akebono, but I have seen no "official" confirmation of that rumor, and if true, that still would not mean that Akebono ended up as the parts supplier.maybe I should be more specific. I'm looking to replace my pads and rotors. I'm going to get my stock rotors turned so a fresh surface can be exposed so that I can use them them at the track and beat on them without worrying about having to drive home on them too. The front FOG light mounts have been modified and the rotors already are ducted inside to out (which i'm not sure is even right), and i was loooking for the X10's or X16's from Carbotech.
But I want some decent rotors to match up with some decent pads for daily driving. I'm not a crazy fast driver, but I do like to corner and brake hard. Pads are important, but IMHO so are the rotors and i want to make the right choice.
So I was looking at a set of Rotora Ceramics for pads. Low noise, low dust simply because I like a clean car. Quite frankly I'm anal about a clean car. (unless you have a better suggestion which is always welcome)
I degress. So in my search for rotors I couldn't find any feedback on these two brands RPM sells. They seem reputable, but frankly I just don't know.
That said...you bring up an interesting angle which I didn't think of. Are our OEM rotors certified? If so..they are AC Delco?
Your recommendation on Raybestos has changed my tune....as it was another reputable aftermarket I wasn't aware of. Raybestos isn't as commonly found here in Canada as it is in the States...come to think of it I don't remeber seeing one.
Anyways.....thanks for your help this far...still intersted to learn more. I've read some great articles, and posts on the topic that have this far explained a lot to me.
I would wish that someone, perhaps a non-interested third party, could do some real world tests on various brake components.Official website

I suggest you start with Crossbow's excellent summary here.

Amen, brother. I think a lot of us would.I would wish that someone, perhaps a non-interested third party, could do some real world tests on various brake components.
Undoubtedly, there are some reputable manufacturers whose products we all would trust completely. At the same time, we all know that there are some bad models from some very good companies, recall campaigns due to design defects from giant corporations. (The spate of laptop computer recalls this year due to batteries that could catch fire is one example that comes to mind.) The peace of mind that D3EA brings is that it tests the rotors in vehicle-specific applications. That reduces the chance of error due to design defects, and leaves only the manufacturing defects you allude to above as potential sources of trouble. As to the manufacturing defects, I think you can rely upon manufacturer reputation.Are there a lot of less than OEM quality rotors out there? Yep.
Cheap rotors are made quicker, thats one of the biggest differences. The amount of time the rotor casting is allowed to cool in its mold has a lot to do with its strength and durablilty. The cheaper companies pull 'em out quicker to meet production quotas that let them sell cheaper.
Tire Rack makes an excellent point about balance in braking performance, and here again a cheap rotor may have some wide tolerances in its manufacture. But I still dont see them saying that if you don't buy D3EA parts you're going to be asking for trouble, it seems to be more of a piece of mind thing that you buy yourself with something like a certified rotor, the knowledge that its not going to fall apart or suffer from erratic performance due to substandard manufacturing.
