FC3 Caliper retrofit
#63
from what i can find its basicly the same as the fc caliper just the out side is cast a little thicker other then that it uses the same pads and guts. the mounting points i think were the same also since the adapters for rx7 brakes on a ae86 are the same part for fc and rd calipers

I have definitely seen a Miata race car with FD calipers grafted onto it. They were raced at the professional level (I think Grand Am/Motorola Cup level) that were probably built and raced not too long after the Miata first came out. For some reason, them being in SPU class sticks in my mind but it has probably been at least 5 years since I've laid eyes on them in my friend's old SCCA "community" garage.
I have a spare set of FD calipers that I have thought about putting on my Miata. The only issue with using these calipers (as I also own a FD) is that you can't get pads in as many compound types for the backing plate like you can for a Wilwood/AP/etc. caliper but there are plenty for street and track.
I don't remember exactly where the fluid runs through them but I have seen at least one of them that was a parts store rebuild that leaked from where the two halves are joined. The FD service manual mentions that you should not loosen the bridge bolts, so anywhere near that seam is definitely off-limits for modification. I have not had to take one apart that far to rebuild it as I've been able to do replace seals without breaking down the caliper...
Hmm. So, I just need to get bigger brakes for my FD and I'll have a set + spares for the turbo Miata.

I rested a a wheel on the caliper/rotor combo yesterday and there is 10mm between the mounting point of the wheel and the rotor hat. So figure a 12mm spacer would probably be the ticket. Keep in mind my wheels are a +40mm offset and have kinda thick spokes.

This isn't going to happen til I can afford new wheels, flares and wheel spacers. In other words, its not going to happen any time soon. There is just no easy way of making this work.
