confirmed.

any RX7 with a five lug hub has these calipers.

i just scored some at my local JY

 

Whats our time like looking like for this one?

 

They are planning to do the fab work next Saturday. Then it is off to get them mass produced.

 

I'm in for a set of these damn things asap.

 

WOOT!!

Curious about materials, Do we know yet if they're going to be Aluminum or Steel?

 

Personally I want Steel (Coated) and this is what I have asked for. Stronger, and less chance of someone stripping any threaded holes. Weight won't be much of an issue since they are small brackets.

 

SO IN! have to make a trip to the junkyard on monday.

Anyone else wonder if there will be any issues with brake lines?

 

Mark,is there any chance you could have rear caliper brackets made to retrofit the 01+sport brake rotors?

 

Good deal, I don't want aluminum either. Weight isn't a concern for me, at all.


As for lines, I haven't had a good chance to look at things yet, but a miata uses a Banjo fitting on the caliper, where the RX7 uses a hardline and double flare at the caliper, but goes to flex hose on the hub bracket.. Odd, but don't think it'll be a problem. Just need to source some different lines from SSBC or something. Will get on that here in a couple days and report back what I've found.

 

Ok, these aren't my pics, I found them on the net. Anyways, these pics show there is NO OFFSET IN THE BRACKETS!!! It's a piece of flatstock with 4 holes. That's it. This kit used a couple small spacers to get the offset. Basically a thick washer that's the correct thickness for proper offset. The spacer goes between the bracket and the caliper. I have a lathe, I can easily turn these out.

Now I know I can make these cheap. Also I see no reason why these couldn't be aluminum instead. Who wants brackets for 30 instead?

 

those are from that japanese website posted earlier.

if you can make them for 30 bucks, im so down. But i think steel might be a better choice due to the expanding properties of aluminum. These will be under extreme temperatures.

 

The calipers are made of aluminum. They'll probably be hotter. I don't see aluminum being a problem myself, though they could be made of steel as well. Steel is cheaper, aluminum is easier to machine.

 

i see. are you going to follow what is done on that website?

you need to shave off the mounting points on the brakes themselves and they are suposed to be mounted on the outer bolt holes which hold the calipers together i think. i should tear apart the brakes and rebuild them while im at it.

 

I don't see a reason why these couldn't be laser cut as long as they have it setup right and they don't have warp issues like some laser cutting companies. The flanges could be lasercut and re-flattened or squared. The spacers would be a simple operation as well, there is probably spacers that you can buy to spec off the shelf already even.

 

Be careful tearing apart calipers, some companies never made the parts to rebuild their calipers available to the public. If that is the case you're better running them till they have problems then buying remans elsewhere.
Mazdatrix might carry the correct parts or maybe Ben(mazmart) would know more about it.

 

got it.

one thing i did notice more closely as i read through the website and i finally got through it (google translations have a limit on the understanding of translations sometimes). The guy had problems with his wheels. Reading more, if your wheel mounts FLAT on the hub without any real space (like some sportmax or rotas) you WILL hit. K1's seem to have a large amount of space so you wont have problems if you are using these. you need a spacer to clear it if it mounts flat along with the spokes or wheel

I went further through that website, and it seems they also have a rear kit. I didnt read into the details, but it seems you can also use the rear brakes of an FC, and will bolt on directly without any real fitment problems.

 

I'm in for both front and rear brackets, (or fronts only if that is all that is made).

 

I'm in for a set of brackets.

 

FC rears bolt on with no adapters? I might pick up some at the junkyard and try it. Don't the miata front calipers bolt onto the rear without an adapter as well?

 

The pics are using Miata rotors, we have full intentions to make brackets for the Corrado Rotor, and *maybe* the stock 1.8 non sport rotor. We don't plan on cutting the ears off unless we have to.

I will know more when they start working on it next week.
