not mine. i believe it was on this car:
http://www.miata.net/motm/2005/moti.html

no joke. but for $380, it's really hard to beat unless the rotors are completely thrashed...

Good god.. those would be on my car right now if he lived in KC... Sucks. I don't trust EFTs for something off craigslist..

seller deleted his listing.... What ever happened to someone making brackets so we could use rx7 calipers?

Someone was selling the RX7 setups on ebay but did not get enough interest I dont think

I've tried to research what was required to use those, but never could find anything. I'd be interested for sure.

If you know someone who can make the caliper adaptors, we can make a topic to subscribe. I know there was a Japanese site, but when I asked if I could order a set I didn't get any response.

Well I'm interested for sure too...

If I had one to "look at" I'm sure that a cad drawing would appear that I could have replicated here locally... :)

I'm pretty sure those Japanese brackets are pretty pricey and are hard to get. I'm looking at making custom brackets to put them on my car, but have been to busy to get too into it. If someone was offering them for sale, I'd be all over them.

That reminds me to pull the calipers off my FC shell before I sell it.. It seems simple enough, surprised that nobody has made them.

It is pretty simple, just have to drill 4 holes, the only trick is the FC calipers have to be offset a bit.

I might tackle this..... I have both an NB and an NA. so I could have brackets done for 1.6 and 1.8 cars..... or done around NB sport package brakes (if I pick up some front rotors...

My Fab guy is crazy good..... I'll talk to him and see if he's interested. I may do it for my car anyway, but It would depend on interest to see if I'd have em manufactured....
He also Has Brembo calipers lyin around, both from STI's and Evo's if that might be a better solution????

Would probably be best to stick with 4x100 bolt pattern rotors that will fit in stock wheels. The sport brakes fit inside the 6ULs, that would be a very important part of how many you would be able to sell. If this turned into a "cheaper than wilwood" option i'm sure you could sell plenty. Long as they fit inside 15" wheels you should get plenty of interest.
Part of the reason to go with the wilwoods is like 11 lbs of weight loss divided amongst the 4 corners. Something like that anyway, remember reading something like that by emilio.

A lot of people who do this swap use VW corrado rotors. I believe they are about the same size as the FC rotors. Fitting the caliper under 15" wheels shouldn't be a problem, as the FC can with 15's. If you need some calipers to fab up a bracket let me know. I've got a few sets sitting in my garage.

Fastbrakes makes a kit for B13 & B14 Nissan's that used to use the Corrado rotor. For some reason they're using a different rotor now, not sure why. And it's redrilled which is a bummer, because the Corrado's are nice and cheap, and readily available.

It's pretty odd that Fastbrakes doesn't make a kit for Miata's. I actually have a brand new Fastbrakes 11" Nissan kit that I'm selling, now that I'm moving over to a Miata.

OK, I'm thinking we go with the stock sport package brake rotors.... I'll need to talk to my guy on tuesday, and then go from there.

Building the brackets one by one would be costly and time consuming.... so I need to find a way to have them produced in a quantity after the fact...

And what size are the sport pkg rotors?

C

90-93 9.3"
94+ 10"
sport 10.6"
corrado 11"
FC 10.9" (I believe)

Corrado rotors are very inexpensive. I don't know how the thickness compares to the sports, but if it's similar, they might be a good way to go.

C

Yeah sport rotors are pretty tough to find compared to the corrado rotors as well.

Corrado rotors are .865" thick, still looking for specs on the sport rotors.

Looks like the FC rotors are .865" thick as well.

there's a post on m.net a long time ago about what was necessary to make the corrado rotors work.

maybe the title of this thread should be changed.

I'm interested as well, I have stock 95 brakes with hawk blues and they work very very well but it couldn't hurt to upgrade right??

Will Escort GT caliper brackets fit for the 1.8 brake swap on a 1.6? Or just Miatas?

maybe we could have the "off topic" parts moved to a new thread?

Yeah, would definately get more attention .

I pressed the https://www.miataturbo.net/forum/ima...ons/report.gif button.

From what I read somewhere the original Miata "Big Brake Kit" from Goodwin used the Brembo/Wilwood set-up for the Corrado modified to fit.

Then they got around to making the Miata kit.

So all you need is the FC caliper, bracket, and rotor, then just redrill the rotors to 4x100 and they're bolt on?!?

Yeah, that would work. The bracket has to be custom made to fit on the miata hub though

"Custom made" = Drill holes? lol?

And cut the metal to fit around the hub and caliper, and offset the holes a bit. Like I said, it shouldn't be too hard of a job, I have all the stuff to make some brackets for my car, just haven't gotten around to doing it yet.

airbrush1, if your fab guy wants to make a few extra sets, I'll take one.

What happened to the ones from the 929?
Wasn't someone from here working on that project?

what I'm thinking is I get 1 set made/welded by hand.... and then go from there as far as getting copies made by a competent machine shop.... I'll need the first set done first though, so don't get all happy yet.

Also, if this works out and I can get em made up, I'll go through the the correct channels for a group buy.

I'm talking with my guy tomorrow. We'll see if he has the time to do it, and what my out of pocket would be for the fab work, and go from there. If it's too expensive I may not do it, there's also the issue of what he would make off of any sets I had made, since he would be responsible for the design and fab work.

ooh, and could someone MIC a sport package rotor for me if they have one layin around?

i have access to a manual mill and pro/e. if someone were to give me the necessary dimensions (caliper offset, locations of the holes for mounting the caliper as well as the holes for the spindle mounting tabs) i could probably rough something up.

I thought the popular part from the 929 to swap over was the mc/booster? Never heard anything about the calipers. :confused:

Here is the company in Japan that makes the brackets:

odd.... it looks as if things need to be ground off....

also it seems as if people have issues related to how much fluid the MC can push.... However it doesn't seem like the available big brake kits come with upgraded master cylinders....

We're (www.driftingjellyfish.com) super close to completing our RX7 t2 4 piston caliper retrofit kit. Just the brackets, you have to source the calipers. It's built around the NAPA/OEM sport rotors because they're super cheap and easy to find. Just an fyi for people looking for/at options.

What is the planned price point for the pair of brackets?

Thanks.

I'll be down for a set of em.

any pics of your progress Jake? I'm not going to mess with this if I can just buy brackets

I'd be down for a set as well.

http://www.napaonline.com/MasterPage...d=3&SubCatId=4

Napa doesn't list a price for the sport rotors, anyone know how much they run?

Your link doesn't work, it's probably cookied.

What year sport rotors do you need? I just called and asked about 99 sport rotors and he quoted me $73 a piece, for a premium vented rotor. Said they didn't carry anything else.
Standard rotors for regular miata 1.8 brakes are less than $20 a piece.

Edit: Just called and talked to another guy asking for an 03 instead.
These are lifetime warranty.
Front: $34.99
Rear: No price, they don't offer them for any of the NB years

Maybe you guys can get them local, appears I can't. At least not from Napa.

have you guys considered larger brake master cylinders. with a stock m/c pushing many more brake pistons it could make the brake pedal feel spongy.

Anyone know or tried?

A lot of people use the 929 master cylinder and brake booster. That is what I plan to use.

It's quite likely that I have a shit ton of 929 brake parts at work. I'll look tomorrow. What specific years retrofit? How hard is the job--PnP or fab involved?

Jake, please PM me about this. I would like to be in the beta program, if possible. I can have the calipers as soon as tomorrow.

Ben

Don't know how many people you are looking for but I would be interested as well. I have the calipers sitting in my garage.

Check this page out:
http://www.geocities.com/miata_10am/...kes/brakes.htm

I have the booster and master cylinder in my garage, just haven't gotten around to putting them on. I don't rememeber the exact years, but I want to say it's something around '92 or newer. I remember pulling something off of an older 929 and the master cylinder looked about the same size as the miata. The one you are looking for will be obvious, it'll be a 1 inch bore.

Here's some pics of the 929 mc sitting in my garage

Bigger brakes..Is everyone having that much trouble stopping? I have more issues with the tires not handling the braking lol

If I miss someone's question you guys can email me direct at jake at driftingjellyfish.com

Price is largely dependent on quantity and what needs to be machined. Our engineer says the bracket needs to be offset but to cut down on machining we're going to make it out of a single piece of metal and try to use a small spacer to give the correct depth, mills are more expensive than having something plasma cut. The bbk from monster miata employs the same technique. Haven't nailed any of this down yet since he hasn't run the physics through pro eng but we don't anticipate a problem. So all said and done I'd like to see the kit get shipped for no more than $100 and I'd really like to see the manufacturing be cheap enough for a $75 price point. You guys can definitely quote me on that.
Call NAPA and ask for 2001 or 2002 sport rotors. They're a really nice quality single piece. There's a huge aftermarket for those rotors but I'm using OE equivalent to spec the kit. They were around $40 a pair the last set I got but I was flirting with the girl at the counter so I suspect a discount was involved :). I'll probably get a few sets to carry on the site for people who don't have access to them, but they're heavy as a mother fucker so shipping will be a bitch.
As soon as I get the short run in hand for testing I'll let you guys know. Ben, MX5Roadster feel free to email me, or anyone else for that matter and I'll update you with progress.
Unrelated but exciting to me, I should have solid motor mounts available very soon along with the diff mounts. yay.

One more question Jake. Do you expect these to clear a 15" +40 wheel? The wheel will clear the BBK kit.

They will clear the 15x8 +36 6UL wheels. I'll try to test fit as much as possible beyond that. I've got a buddy local with the old design chaps, I'm hoping it'll clear those so that those people will have an option since those wheels aren't bbk friendly.

Cool. I also have 6ULs, but they're 40 offset. If they fit Chaps, they'll probably fit anything.
