ya i have heard of the helical as well but i am not very familiar with it.
which rx3s did they come in. and what did you have in your 2? thanks
oh ya Crit why are you making brake braket when you could just buy them, thin you gonna save enough to make it worth your time, or what are you thinking. by the way how much would an extra set cost me. **** you might want to make a few set if you have a template made. Let me know matt22

helical is the same as Torsen.
it is more desired for road-race/autoX than the clutch type..
however, if you are into drag or drift a good clutch type is the way to go.

Oh, and the reason for making brackets is that you COULD buy them, but can't anymore. Another forum member is looking at making them out of welded steel plate or machined aluminum, depending on what a person desires. If you're interested (these work on RX-3 as well), shoot me a PM with material preference and we'll look at what it would cost to fab 'em up. Here's what the assembled brackets look like, whether welded or machined....

when i remove my old diff I'll sell if for the cost of the RB gears.
even though I have modded it to LSD, and it has a really really clean and re-painted pumpkin. as of now this diff only has about 200 miles on it.
Looking at the helical set-up I am concerned that is may be a large axle version.. So i'll be machining axles too..
If so, i'll be using the 84/85 GSL axles so i can retain my wheels.

those are similar to what mine look like.
the left bottom hole is not needed, so you can save alot of machining cost by not cutting that big hole where the axle tube goes.
the next part of it is the hardware. The 4 bolts that go through the retaining plate, throught the axle tube flange, then into the brake adaptor plate should be flanged bolts with a side of the flange ground off.
I have some friends in the fasteners business, if you guys want i can look into buying a bunch of these and have one of my shop assistants start grinding them down...
you'll need 2 aluminum spacers. about 1/4" think, otherwise, if you machine it into the plate it will cost alot more because you'll have alot of waste.
My plates are mild steel and are pretty light all thinkings considered..
I think if they were made from a 6061-alum it would be plenty strong enough. and would save some unsprung mass.
Alum is cheaper to machine than steel, so the cost would be about the same.. (alum cost of material higher, machining lower...)
IF you did go alum i would feel alot safer having that bottom left hole there and material wraping all the way around the axle tube.
Honestly, if i had the time i would have a machinest make the plates for me, I'd have lines made, and put together a whole kit.
one other note, is this plate uses the stock 81-85 calipers,
have you priced these in rebuilt form? They are actually more than the Wilwood calipers.
I have a Wilwood set-up I can copy and put together in kit form as well.
Maybe we should colaborate. I have machinest in school who will make me anything i want for next to nothing.. maybe put together a few different kits and make a group buy for the RX-7 club and maybe also the vintage rotary forum.
let me know your thoughts.

I'd be down for any type of brake kit for RX-2s, would these larger rotors work with 14" wheels or is it still pretty much up in the air?
Who already makes a kit? Anything to replace the rear drums? I haven't seen much for RX-2s, but what I have seen was a front disc replacement only.

Yes guys there is some cool stuff in the works. This kit will bolt on 81-85 GSL rear calipers to a Rx3 and Rx2. Possibly some other rotor / caliper combinations will be announced as well.
Thank you all for your design ideas, I think we have it covered. Billet is a possibility, for a race version. Standard parts are mild steel construction with zinc plating.
