Nice pics. I had the same 3 sets of brakes laid out in my garage a few weeks ago. :)

Even though I was running the 99 spec big brakes, I gotta say how much I love the Racing Brake setup. Lots of braking torque! These things are awesome!

Great to hear that!!! I can't wait to put those RB brakes on my blk FD... If I ever get put together... LOL!

Herb,

Great pics. Where did you get your 99 RZ brakes? I knew there was a group buy a while back but I haven't seen a source for these since.

If you race or autocross, Mazda Motorsports is the preferred place.
