I swear to god that I read no here earlier that an FC caliper will boit staright up to an FC?

...but how can this be if the rotor is larger?

I dont care so much for the bigger rotors as much as the sexy calipers.
(Mine need replacement soon, and I was going to get some remaned FD ones instead because I heard of them fitting.)

So if I only want the caliper, and dont care about upping the rotor size, do I still need the adaptors?

me=confused.

just upgrade the rear to the same size with the corksports spacer you are not gonna have a problem on brake bias

* only IF whatever Ted post was actually indeed a direct bolt on for the FD rotor, which i doubt*





the FD and FC caliper is the same, but the factory mounting position is different, so the FD can use a bigger rotor, i dont see whats wrong that

why the **** would you want to "upgrade" to the SAME caliper without upping the rotor size

the only reason the FD have better "factory" brakes is because it came with bigger rotors

I think he just wanted the FD calipers cause they were better looking.

The only way upgrading the rear would give the same brake bias would be if you increased the rear brake disks the same percentage that you increased the front disks, and even then there may be other factors. It would probably be close enough not to make much difference, but its still something to be aware of.

exactly...

but now that I find out that the rotor size is different, I will consider that as well!


PS: You dont seem to need a brake bias adjuster for those AEM big brake kits that use a bigger rotor but retain the stock calpier by using an "Extension" bracket.


This seems exactly the same as those brakets.

no, you dont *NEED* one because larger diameter rotors in front will just increase the front brake bias, making the car more stable under braking. However, the bias wont be the same as it was from the factory, and more understeer under braking may not be what many people are looking for. Plus, you'll lock the front tires earlier than the rears, and will not be getting the best overall braking performance from your brakes/wheels/tires.

If you're playing with the factory brakes for performance reasons though, you'll probably already have a bias adjuster in there.

the factory front and rear rotor is the same size
so as long as you upgrade the front and rear rotor with the same size rotor you will not need to adjust the bias.

toplessFC3Sman

Yea, so you'd be increasing them the same percentage and not need to.

Almost the same, but not quite. Minor differences will add up when increasing the size and the proportion of braking force if not accounted for.

The fd caliper is a direct bolt on replacement to the fc four pots.

https://www.rx7club.com/showthread.p...ht=fd+calipers

I noticed no difference between the fd and fc four pots in breaking power. But agree that the fd calipers look better, and I had some lying around.... I'm definitely looking into this bracket. I think the fd rotors would complete the look, if not supply a little more breaking power.

i think i'm going to make this - have to talk with my friend who does cad - who would be in for this?

someone somewhat did this already, heres a link

https://www.rx7club.com/suspension-wheels-tires-brakes-20/mandeville-style-4-wheel-big-brakes-fc-feedback-needed-739122/

but there was a problem there coz you'll NEED 17'' rims for those to fit, and alot of us here have 16's

and the FD rotors offsets are not the same as the FC, i am not sure if it is hitting the suspension or what, you'll have to research that as well

if you do make something that fits under 16's i'm totally in

RETed.. if you can post me a link or a katakana/hiragana word search for this adapter plate i could order it and work with someone on the forum to get these made.

What good do larger rotors do if the pad is the same size? Minimal. The contact area is the same but the rotor is larger which could possibly offer a little bit more heat absorption. I think just buying good pads will get you a lot further.

It works like leverage... The bigger the brakedisc, the bigger the leverage, more stopping power.

i swear what ever REtard posted was for the rear, no way that adapter plate is for the front

this should be it, the last item on the page

In effect, from a braking force point of view, pad area is IRRELEVANT. What's important is the friction coefficient, the lever arm (approximately from the hub to the pad centerline) and the clamping force. What the FD brakes do is increase the lever arm for more braking force and add mass to the rotor for better fade resistance.

Pad are has effects in terms of wear rates and fade resistance mostly.

RETed

Yes, and I still do.

The problem is that those pics were pulled off YJA, and the seller did not mention who made them.
I assumed it was some one-off custom pieces.

I don't know of ANY Japan company that is making brake upgrades for the FC3S.
Aside for the backstock of overpriced Trust / GReddy stuff and the stuff Corksport tries to sell, I have seen ZERO brake products, period.
I think there's more stuff in the US for FC brakes than in Japan!

What Trust / Greddy stuff? You mean adapters or BBK's?

Let's not forget the ultra-expensive Endless 6-pot BBK's, 324 mm discs and big calipers look nice.

So, Ted, from your viewpoint, if you didn't read the listing and just saw the pics, do the pics you pulled from YJA look like brackets for the fronts or the rears?

RETed

BBK.

I think they are discontinued?
I haven't seen the Endless ones on YJA, but I see the Trust / GReddy ones all the time.


Those pics are straight from the YJA auction itself.
The listing did specifically mention fronts - i.e. "F".
It does really look like the SuperNow pics in that link that bitch posted above...

What did you search for.. i search FC3s bure-ki and i dont get anything like that. id like to know what you used to search so i can check it out.

I wasn't finished reading the thread and was going to reply, but black91 did a nice job of explaining the rotor size does matter due to the increased clamping force further from the center.

There's quite a big difference between a brake bracket, and say, a header. One requires some research, trial and error, and calculation. The other requires a brain and a micrometer. A bracket is kinda just bolt on.

Note the date on the thread.

Buy the rotors, take the spindle off, and take them to a machine shop. Take them a pic of the bracket too.

I'm going to resurrect this from the past based on a recent thread.

Regarding front brake modifications this thread suggests:

Has anyone made these FC Caliper/FD Rotor adaptor brackets commercially available? More importantly, has anyone used these brackets an extended time (especially under track stressed use) and can report successes and/or issues?

Case in point, on the surface I'm not a big fan of any kind of adaptor for something as important as brakes. BUT, I'm open minded enough to anything that has been track proven extended term that would provide upgraded braking for our FC's. Especially if using broadly available wear replaceable parts such as pads and rotors.
