Does anybody make big brakes for the rear of the FD? I can't find any companies that make them.

 

Mazda '99 spec

 

Only option that maintains the parking brake:

David Breslau makes a bracket (if you can get him to actually make any) to fit Wilwood superlites in the back but you will loose the parking brake in the process. It uses the same rotor as the '99 rear brake setup shown above.

And you just missed out on a GB for the Precision rear brake rotors

Other than the obove you want anything you're going to have to start looking too Japan and/or at some pretty expensive custom made setups.

You should also justify the need.

The 99-rears use a 12.4-inch rotor with a relocated 93-95 single caliper. $800 for all parts including pads through Mazda Motorsports.

The next step up that I'm aware of is a 4-piston caliper setup by Brembo using 12.6" rotors. You lose the parking brake and they cost $2800 from N-Tech Engineering. http://www.ntechengineering.com/inde...d=6&model_id=2

I don't know about you, but I can buy a lot of things for the $2000 difference.
