Interest In A Proper STi/Evo Caliper Adapter Bracket? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

*ManoNegra* · 08-26-2009, 01:48 PM

I have a set of STi Brembo calipers coming my way
and plan to make a nice set of brackets for myself
since I have the means to do so

I've made and sold a few sets of brackets to some members on the forum
made from measurements found on this well known thread (page 7):

Check out my new BIG BRAKES!! anyone else do this yet???

Those worked well but as stated in the thread, some grinding is usually required to clear some of the calipers features.
Also, there seems to be a slight difference in hole separation between Evo and STi calipers.

So the question I have is: Would you guys be interested in a proper set of
adapter brackets that would work for either caliper?

Features I have in mind:
- CMM data for perfect fitment
- CNCd 6061 Aluminum for lighter weight
- Hard anodized for ruggedness (would look baller aswell)
- Helicoil inserts to protect the threaded holes from repeated installs

All of this - R&D, design and manufacturing - would be done in house by a friend and myself.
That means the cost of these parts won't be astronomical and about the same as the typical brackets offered for sale go for.

Feel free to chime in with any questions/observations/concerns.

*ronmcdon* · 08-26-2009, 02:40 PM

I think there's certainly a market for something like that.
If you can offer this as some kind of set to make it a plug & play ordeal, that would be nice.
Complete with needed lines, hardware, maybe even pads, proportioning valve, etc.

Also wondering if you would need a larger or different type of brake proportioning valve.
Maybe even a larger brake booster.
From the previous thread, seems like some of the ppl were having brake modulation issues.

Good luck with your project, and pls keep us updated.

*chibo* · 08-26-2009, 02:46 PM

I'd be interested.

*S14_Kouki* · 08-26-2009, 02:49 PM

Evo/sti brake upgrade is a awesome idea. I dislike sliding calipers ie stock 240sx brakes. I upgraded to 300zx brakes (fixed calipers) and thats a big difference but if i had the chance to buy some evo/sti calipers and use them I wuld over then 300zx upgrade. Now my question how much more money are evo or sti brakes comparied to 300zx and whats exactly the size and weight difference?????

kalypso123 · 08-26-2009, 03:28 PM

as long as the bracket isnt 800$

if its priced reasonably... people will love it.

*garagelu* · 08-26-2009, 03:38 PM

If they were made out of steel, I would buy them. If they were made out of aluminum, probably not.

*S14_Kouki* · 08-26-2009, 04:03 PM

Yes please dont make them out of aluminum, just becuase under hard braking I dont want to take the chance with something bending/braking. Well aluminum is very strong I just dont know about using aluminum brakets for your brakes. What are other companys using for material??

florante rea · 08-26-2009, 04:07 PM

aluminum will not work, steel is a better choice. as for the one design evo/sti it will not work, i have thought about it for a long time to make a similar concept. just make just one application for each calipers. just make it simple.

we wouldn't go this route because
most of those things are already available
- there are plenty of sources for lines
- everone has a different opinion on what pads they like
- adjustable proportioning valves exist and are pretty cheap but require a good amount
of work to implement.

also, aside from the proportioning valve, we don't make any of that
stuff in house
we would have to source lines, pads, etc
there really wouldn't be a clear benefit we could pass on

the problem people were/are having is from not doing a complete job
i.e: z32 bmc, front and rear calipers imo

Price varies but ~$500 for the calipers.
They show up here every once in a while... ebay... craigslist

I don't want to quote prices since this thread is just a feeler for the moment
but it would be for the same that the brackets usually sell from
do a quick search on the For Sale forum to get an idea

What do you base that assumption on?
z32/Evo/STi calipers are aluminum, no one is complaining of them failing
rear z32 uprights are aluminum
we are a prototype machine shop and have done similar things for other applications without problems
yes, steel is stronger but not necessary for this application and not to mention heavier
if there's an engineering reason, then I'm open to hear it
even the hard anodizing is a bit on the overkill side

the only thing I'm concerned with is the threads for the bolts
it's easy to damage them if one isn't careful
hence the helicoils

*S14_Kouki* · 08-26-2009, 04:27 PM

Aluminum will work just fine for the application. But for what I was wonder under alot of stress will the aluminum brakets hold up to the same stress as steel brakets hard braking puts a hell of alot of heat into the break system. Yes z32 uprights are aluminum but thats a very big piece compared to a braket alot more material=stronger part we r not worryed about aluminum calipers failing what we are worryed about are aluminum brakets failing.

*K_style* · 08-26-2009, 04:40 PM

I think there is good market for that. . .

I already purchased one from florante rea before. . .

and will need another one . . set up is good..

awesome stuff

*ixfxi* · 08-26-2009, 05:01 PM

cool......... interesting

i recommend steel, i believe my stoptech adapters are steel as well.

*garagelu* · 08-26-2009, 05:13 PM

its not the actual aluminum body I am worried about. Its the aluminum threads that are more of a risk. Helicoil would help it but still not as strong as an all steel thread.

Look at all the big brake manufacturers. All their brackets are made of steel. Hmmm I wonder why? It is all about safety. And yes they are heavier but is it enough to disregard safety?

I've been running my own 6061 aluminum custom made sti brackets for about a year and a half now with not one problem. I have been wanting to copy the design with steel for a while but have not got around to it. Too much down time on the car but if I could buy some that were within a reasonable pirce, I would shell out the money pretty quick.

Ali 556 · 08-26-2009, 05:44 PM

dunno about you guys,

I have a '95 S14 with Auto booster and EVO brakes Front AND rear (yes front AND rear).

I've made the brackets my self after a lot of trial and error ordeal. out of steel..About the lines STOCK Nissan lines are Direct bolt on to the EVO/STI setup...Along with Z32 BMC you will get crazy brakes that can stop you on a fucking dime...

Proper bleeding of the REAR brakes will get you a perfect balance of the brakes..hell on the track EVO brakes along with Ralliart TARMAC pads front and ENDLESS M-power pads rear...NO fade what so ever and GREAT balance the handling was controlled by my HKS coilovers.

It's not rocket science..it's a plate with some holes in it so i think a proper price of 100-150$ is perfect

true
what I'm saying is look at the part of the calipers where the bolts go
they're not very thick and withstand the forces and heat associated with braking pretty well
those would have to fail first before the brackets do
also the bracket would act as a triangulation unit making the assembly even stronger

I wonder if that's an actual engineering need or a cost cutting one
steel is usually ~$1.50-2.00 per lb vrs ~$2-3 per lb for aluminum
and what type of steel are we talking about
mild steel, iron, stainless, chromoloy, etc, etc....

helicoils are steel and helicoils threads are actually stronger than bare steel ones
they can also be removed and replaced if needed

you could, but again you don't need to

we could make them out of steel, hell it'd cost us less
but why? is not a better solution

Ali,

I've got pretty much the same setup as you. I have ABS, ABS booster, z32 bmc, front and rear sti calipers. I just switched from project mu pads to hawk pads and am not liking the downgrade. The project mu braking felt so much more responsive and crisp.

Just curious, what rotors are you running?

*S14_Kouki* · 08-26-2009, 06:07 PM

Yes after everything is said and done for prob 95% of ppl on this forum dont road race or drift enough to have to worry about braking brakets. So im sure they will do the job and do it just fine.

I have heard that helicoils are stronger than bare steel but I think its just hearsay or marketing. Can you tell me why you say this statement? If this was in a different application, I would say that there is a possiblity of the helicoil pulling away from the aluminum thread. In a caliper bracket the only loads the threads will see are lateral or horizontal load. There should be no vertical loads.

There is already a couple people selling aluminum brackets. Why would you want to compete? I can almost guarantee you that if you sell steel brackets, you will outsell the aluminum ones. People arn't going to look at weight being a factor since its so minimal. They will look at the price first and then the safety factor. I say powdercoated black mild steel is the way to go. Another option is stainless steel but SS can sometimes be same or more in price than Al.

*Jakob* · 08-26-2009, 06:56 PM

ha if you put out these brackets ill buy another pair :P

so that means, do it!!!

No, it's a fact. They're an aerospace industry standard for threaded holes.
The majority of the work that we do is for the aerospace industry.

YouTube - helicoil

I agree with you
I'm not worried about those loads
I'm worried about cross-threading a steel bolt into an aluminum thread
I've done it before and it's a pain in the ass
helicoils would make the threads a lot more durable and
distribute the torque on the bolt evenly

Quote:

- because I'm not happy with what I see and have the means to make something better
- because I'm one of those people
- because I can

Quote:

Not worried about that
I care more about making something better

Quote:

I care and I'm sure some people that care about their car's performance will too

Quote:

Price will be similar if not less than what being offered right now
I would never make/sell/endorse something that I feel puts people's safety in jeopardy

Quote:

powdercoating isn't cheap and I personally don't like the finish all that much
mild steel is gargabe, I wouldn't use it if it were free
if I were to make these out of steel it would probably be 304 stainless.... but I won't
we could make them out of titanium too (we have some laying around)
but again, there's no need to
cost of material isn't something we take into account when designing parts
we pick the material that we feel is best suited for the application

for example, when we planned to make the misalignment ears for the Z32 spherical bearings
we decided that chromoly was the only material we would feel comfortable using and putting our name on
even though we knew that the parts would need to be plated to prevent rust
at an additional cost to us

*DrtyRat* · 08-26-2009, 07:40 PM

Iirc, doesn't the anodizing process make the aluminum just as hard, if not harder than steel?

Slammed180 · 08-26-2009, 07:43 PM

I'm in need of STI brackets right now. I would like to see some other options as far as adapter brackets. I would think steel would be a good option (at least for my personal peace of mind)

Also, I don't want to spend money on a bracket that requires me to modify it in order to clear the calipers discrepancies.

So, I would say yes, there is definitely a market for them.

Not quite, it's more more corrosion and wear resistance process
pretty colors/finishes are just an added bonus

Now, we can talk about heat-treatable aluminum or harder tempers of aluminum
but again that's more $$$ and not needed for this application

*Def* · 08-26-2009, 09:31 PM

Even plain jane 6061 aluminum is as strong as most alloys of mild steel from a yield strength perspective. It'll handle the loads just fine.

My choice would be something like 2024, but the cost is up there for that. For those of you that don't know, that's what they make fighter jet bulkheads out of that pull 9 G's. It's also known as "duraluminum" in the Nissan world(that was a name for a similar alloy back around WWII).

*garagelu* · 08-26-2009, 09:57 PM

Yea if you do a lot of work for the aerospace industry, you probably know your stuff and know more than me. I've taken materials classes in college and worked in a component fatigue lab but thats about it. We did some helicoil pull tests on big chunks of Al a while back. I forgot what grade Al it was though. We basically chose a couple holes in the block and installed the helicoil with a bolt. Then used a press to pull the bolt out to see the carnage. These were 16 and 18 mm bolts used in Caterpillar machines pulled with a 25 ton press.

I would really like to see what you come out with. If the design is better than mine, I would consider picking a set of your up. Have you priced everything out yet so you can tell us how much you will offer these to us at? And when do you think you will start selling these?

No concrete price yet
but expect it to be in the same range as these normally go for
but with a better design and finish
I figure a month and a half is a good guesstimate on the time
these would be ready

So im sure they will do the job and do it just fine. __________________ http://www.fabthis.com http://www.childhoodproductions.com/dbfab/store.html

I would like to see some other options as far as adapter brackets. I would think steel would be a good option (at least for my personal peace of mind) Also, I don't want to spend money on a bracket that requires me to modify it in order to clear the calipers discrepancies. So, I would say yes, there is definitely a market for them. __________________ Blow me, bitches.

It'll handle the loads just fine. My choice would be something like 2024, but the cost is up there for that. For those of you that don't know, that's what they make fighter jet bulkheads out of that pull 9 G's. It's also known as "duraluminum" in the Nissan world(that was a name for a similar alloy back around WWII). __________________ Rear Upright Spherical Bearing Group Buy Redux!!! 92 Nissan 240SX S13 Hatch GT2876R - Constantly tinkering and lots of garage naps...

I've taken materials classes in college and worked in a component fatigue lab but thats about it. We did some helicoil pull tests on big chunks of Al a while back. I forgot what grade Al it was though. We basically chose a couple holes in the block and installed the helicoil with a bolt. Then used a press to pull the bolt out to see the carnage. These were 16 and 18 mm bolts used in Caterpillar machines pulled with a 25 ton press. I would really like to see what you come out with. If the design is better than mine, I would consider picking a set of your up. Have you priced everything out yet so you can tell us how much you will offer these to us at? And when do you think you will start selling these?
