I might be able to get a free set of front Rotors and calipers from an FD. They have less than 10k on them. I was wondering if i could possibly make the calipers fit my 87 SE because im getting new rotors, think it's possible?

i highly doubt it without some serious fabrication.

The calipers are bigger and have different mount locations. The rotors are also bigger and won't fit inside the stock 14" wheels (pending you don't have larger aftermarket ones).

You might have a better chance if this has the 5-lug conversion already done to it.

Yup, the calipers will bolt in on to a FC with the 5 lugs, it won't on a 4 lug

RETed

NO.

And rotors?

I never tried them but I think the consesus was that NO, they won't bolt in.

capn

are the FD calipers any better than the turbo 4 POT calipers?


if not just do a 5 lug conversion

the caliper is basically the same thing
just that the rotors are bigger and they wont bolt in

but for sure... someone did that b4 for "performance upgrade", do a search

Turbo II-FB

yez they will

Ive never compared FD rotors to FC rotors side by side. Can anyone tell me what the major differences are? I think that the actual offset of the rotor hat is different, but not sure what else. I have been thinking what would be necessary to swap over to FD rotors/Calipers, because then from there one could upgrade to the larger RZ rotors, and make for a cheaper/easier brake upgrade than buying a ~$3000 big brake kit, which is overkill for a street car anyways.

The rotor has is completely different on the FD. Being a larger diameter rotor, the caliper would not fit on it to bolt to the hub.

The FD calipers will bolt on. In some ways, I guess they look more modern. I remember someone once mentioning that the FC caliper might actually be a touch more efficent, as it has a webbed design that could potentially dissiapate heat easier...but this is all bench-talk.

RETed

The FD ones are supposedly some special "squeeze cast" process which is supposed to make them lighter, but all intent and purpose, they are all the same.

Do you have a problem comprehending the English langauge?
The original poster did say he had 4-bolt hubs.

you'd be much better off just doing a five lug swap from another FC, the four piston brakes are great with new pads and rotors and plenty brake power for my fc. It would be more time and money than its worth to get the FD stuff to bolt up

therotaryrocket

why would he get the 5 lug conversion from another fc if he can get the hook up on fd brakes, of course he still will need some parts from the 5 lug fc. ive never done this, just read about it and compare my 5 lug to my friends 4 lug, not to mention both 5 lug fc and fd use the same brake pads.

Well, It's a project i decided not to tackle since I ordered new brake rotors, and you guys said they wont fit. Thanks for the Input.
Anyway to make my single pot calipers clamp firmer?
Would I have to upgrade the master sylinder to do that, or modify the booster?
Also, how much of a performance increse do you think I'd get with SS brake lines, Brembo, slotted and cross drilled rotors(+ zinc plating), some Hawk pads rated for the rotors, and rebuilt calipers?
I'm looking for at least a %40 gain over stock, think that'll do it?

RETed

Upgrade to a good brake pad and see if you like it or not.
Hawk HPS is a very good upgrade street pad.
They should have an application for your vehicle.

new pads and rotors should help but i've swapped my four lug to 5 lug after putting ner roptors and pads on the four lugh setup and the worn pads an rotors that i first put on with my five lug swap were soooo much better, theni went with slotted and crossdrilled rotors and some axxis metal master brake pads and it's great i really don't think those single piston brakes are that great

ANy way to make the 4 pot calipers work without doing a 5 lug swap?

digitalsolo

iTrader: (2)

Technically, yes. But it's NOT worth the effort. You have to mix/match parts to do it (as I understand it). Ted can correct me if I'm wrong here.

totallimmortal

i don't think the 4 piston calipers will bolt to the 4 lug hub i also think that the 5 lug may have a larger diameter rotor as well as having vented rears. Five lug conversion is the way to go in my opinion you have many more options for wheels this way too

Yeah
But right now I dont have much $. 5 lug swap = too much money for me.
