MD FD Calipers on a FC Turbo II

Ok so i just got these FD Calipers Front and Rear,And was wondering a couple thing's i no the Calipers up front will bolt right on no mods needed,And im running the FC rotors up front so there should be no Problem with fitment as far as that's concerned,My Qusetion is will the rear calipers bolt up? And im going to upgrade to Stainless Lines so id need to Know if i need the FD Stainlees Lines or the FC Lines when going about buying,I Know i no of a couple peolpe whom have done this on here but i couldnt find anything on the rears or the lines being the same,Any Help would be Great.

I was just thinking about this same upgrade and would like to know the same thing. Would the rotors be a direct swap too?

the front calipers are almost the same, so they just go right on. the rears i'm not sure about, but they use the same pad and caliper piston size, so i don't think there would be any difference, or advantage to using Fd calipers in the rear.

the FD has a different offset on the rotors so they won't swap over

Yeah i talked with someone at Mazda Trix yesterday and he said pretty much the same thing the Fronts were a directed Swap but the rear's are not so,My plan is to use the front FD calipers up Front and used the FC rotors up front and leave the back the way it is except for upgrading the Lines and running some Hawk HPS pads!

i thought the FD caliper has a different PCD.. so doesnt bolt to the same mounts
.. the main change has the internal crossover port now built into the raised pad that has the mazda font.. when in FC it was a small cast lump.. which limited some wheel choices

What are the advantages of FD calipers? I'm about to upgrade my stock brakes but if FD brakes are better I may just swap the fronts

The casting looks different.
FD/FC calipers use the same brake pads and rebuild kits, so there's no mechanical advantage either way.

Is there full pad contact?
I though the Fd calipers would have an overlap onto the outer edge of the rotor.

Well they definitely look better than the FC. Much cleaner/modern look to them.

Looks like you have something wedged or a hard spot in the pad. Is the spot raised or is it recessed into the rotor?

Is it happening on both rotors? Just bought a pair of FD front calipers for my 5 lug swap so hoping this is not the case.

Ive had clips shift a little bit and make slight contact with the rotor, sometimes only when the brakes were applied and they would shift over a little bit, peening them over would lock them in place better

This happens to me all the time when I install the pads on the wrong sides on single sided calipers.
