I'm looking to swap the rear brakes on my FC with an adapter kit that utilizes the larger 12.5 inch brake rotors from the RS/RZ FD. What are my options (if any) for aftermerket rotors? If none are available, what sources have the OEM's available.
I have been runing StopTech "Power Slot" rotors which I am pleased with. I would like to use them again but cant find a listing for the aplication anywhere.

Thanks,

 

Pretty sure it's going to be hard for you to find aftermarket in the USA. I believe you can get some endless rotors from Rishie (autornd), but I don't think anyone makes RZ sizes here. OEMs are not as hard to get. You can get them on Mazda motorsports. I can probably help you source them from mazda motorsports if you need.

 

Mazda Motorsports has them as mentioned above. I've used the same set for 3 years on the track car and they are just now starting to develop some cracks. However, they use to be $120 a rotor, now they are $190 a rotor! There is a good chance I'm going to send mine off to Coleman to get a two piece floating rotor made. If I do, Coleman can use the same measurements to make you a replacement as well.

 

Wow! $190 per rotor is pricy. It makes the conversion kit that Corksport sells look like a really great value at $334. http://www.corksport.com/corksport-r...grade-kit.html
Perhapse I will try a few sources in Japan for rotors first. If all else fails, I will pick up the kit and use the OEM rotors included.

 

You could try these guys http://www.revolutionbrake.com/ they used to be called Precision Brake Company and they made a nice set of two piece rotors for the upgraded JDM brakes.

 

Sorry for bumping a 4 year old thread, but figured it would be better than starting a new thread for the same question.

So for the RS/RZ/Spirit-R peeps...what are our options for replacement brake rotors in late 2015? Other than Mazda Competition (Mazda Motorsports) are there any other sources? I know quite a few guys on the forum run the larger brakes...it would be nice if we had a source for affordable replacements. When I say affordable I don't mean cheap, but just not expensive 2-piece units such as Project Mu, Endless and other high end rotors...

I noticed we have a new forum vendor that manufactures rotors for the FD, Cquence brakes...it would be nice if they could make us a batch of the larger rotors...

 

I bought Dixcel replacements from Yahoo Japan Auctions which had been given an aftermarket heat treatment:-

??????? ??? RX-7 FD3S 17??? ??1?? ???? - ????!???? ???????? ??????? - ????!

Coped well on track combined with their upgraded street pads.


There's a ton of options though

Thanks Marf!

I was hoping there was a local US solution, but this is good as well.

 

No problem.

I got prices from Mazda UK for new discs, they wanted more than twice what the Dixcel rotors cost landed from Japan.
