hi i bought some big brake discs for my 96 fd, the problem now is the calipers are too small as my discs are 33mmm thick..




which calipers do i need to fit my new discs thanks

 

Usually a "big brake kit" comes complete with new calipers, pads, and rotors....
Can you give us the name of the company that made the rotors? This is NOT a simple issue.
Changing anything on the brakes on these (or any) car needs to be done thoughtfully or else you'll just hose up everything.
Wildwood and Brembo make some popular kits....

 

LOL, did you just buy some random rotors or what? Whose rotors are they and are they even designed for the FD?

 

is there an upgrade for our car... meaning OFF another car... better brakes from another car will fit our car.. jst wondering..

 

Not really.

 

hi, i bought the rotors from yahoo japan and they are brand new, they fit perfect and are fd specific but they are just to thick...




so i need to find suitable caliper, sorry dont know the name they are drilled and slotted and look real nice and fit like an ace except the caliper is now too small

 

How are they FD-specific if they don't fit the calipers??? I hope you can return them, because you have incorrect parts.

 

the fit the fd and is fd specific but you need bigger calipers and my thread is which caliper do i need

 

Jurgen,

What I would suggest if you really want to use those rotors, is to contact a company like StopTech ( http://www.stoptech.com/ ). They'll need exact measurements of your rotors (not just width) and they can see if they have something which might work.

 

Ask the guy who sold you the FD specific rotors. If he's making these rotors for a particular application he can tell you what caliper you need.

 

Maybe they are made for the Mazdaspeed calipers? You can widen your calipers by making a spacer and placing it between the caliper-halfes. Its not a hard part to make, but you will need a cutting machine (or whats it called in english :P ).

 

RZ rotors?

 

thanks for all the help folks, i have bought a billet kit which enlargens the calipers to take 33mm discs

 

I would laugh if you just needed to compress the pistons...

 

RZ rotors are also bigger in diameter, which would require the RZ calipers, not just wider 93-95 calipers.

Since there are NO aftermarket calipers available for the FD that are wider but the same diameter, the ones that Jurgen bought are NOT FD-specific. Unless he hasn't yet noticed that the new rotors are also too big in diameter.

 

Mazdaspeed made bigger calipers!

 

What kit would that be? Could you post a pointer?

 

LOL that is the first thing I thought when I read this thread.

 

Jurgen, measure the diameter of the rotors. That would help determine if they are the larger OEM rotors that some models (RS & RZ, I think) came with. I would also suggest measuring the thickness if the quoted figure (33mm ~= 1.3") was simply taken from the auction description and not verified by direct measurement. My guess is that they are RZ-sized rotors (which are ~315mm or ~12.4" in diameter), which will require the Mazda RZ calipers.
