AE86 S13 brake conversion

[ae86represent]

I have assembled all the parts required to do a full 4 wheel S13 brake conversion on my sprinter.

I have machined the sprinter hubs so the S13 rotors fit over the top, and installed longer studs, the rear drum ass has been removed (T series out of a celica) and the brearing retainers have been modified ect. I have 4 new slotted rotors and a full set of EBC Greenstuff pads.

The next step is to get the mounting brackets machined up. I have taken all the messurements and drawn the brackets in AutoCad so it should be quite easy to get a machine shop to make them for me, my question is this,

What materials should the brackets be made out of. The factory ones look like they are made out of high tensile steel. Would stainless or alloy be strong enough??

Or does anyone know if these items are available to purchace, as this would prob save a lot of hassle and more than a little cash. As these are prototypes only, the design may well need to be changed and another set of brackets machined.

Many thanks,
J.

Cheers oldcorollas.

How would I go about contacting him. Sorry I am new to this forum, can I send him a PM or somthing?

for a proto, just use alloy as it will cut easily on the mill though the stock will be expensive compared to mild steel, so consider using that too.

i have seen caliper brackets made from alluminium often, on OEM and aftermarket/custom stuff, it should be fine to use if you use the correct grade.

don;t use stainless, it will be too expensive and not necessarily the right stuff to use.

This is what I was thinking, billet alloy, light and prob more than strong enough. This pic was posted by BlueAE86 earlier this year.

Thanks for the input shinysteel, I was thinking the same. What grade alloy would you recomend??

i don't know my grades, so have a read here

http://en.wikipedia.org/wiki/Aluminium_alloy

i think 6061 is commonly used, there is a grade designed for machining, which would help out the process, talk to the engineering place who will do the work for you and ask around.

I've used Bisalloy for all the stuff I've had made.

The AE86 to Nissan brakes will look very similar to the one you posted above.

If you are getting them professionally CNC'd, don't expect much change from $300 a side for the first pair.

If you get 10 pairs made they would probably be about $100 a side.


If you have access to a mill and other metal working tools, you can do it yourself with time and patients.

Have a search for a thread I started about this a while ago.
I stopped due to having no time to go any further.

Out of curiousity why didn't you use s13 front suspension incl control arms as well and use an f series rear end instead of t series - some of these even come with rear discs.

I decided to use a full set of S13 brakes as I was hoping that the front and rear bias might have been closer so I diddn't have to use a brake bias valve. Chances are I will still need to use one though. The other reason is T series diffs have off the shelf LSD's available ie. KAAZ, TRD, ect. And S13 brakes have a huge range of high performance rotors and race compound pads available.

As for the complete S13 front struts, I have allready decided on a front suspension setup that should work quite well. Bilstien shortened inserts in modifed standard struts with a coilover seat welded on. Cheaper option than a set of coilovers, and I can get the bilstiens rebuilt and re-valved so they are a lifetime purchace. To get a similar quality damper in a coilover is quite expensive $1000-$2500 per corner normaly.

That being said, as a buget option, doing a complete S13 strut conversion is excelent value as there are several good quality cheap S13 coilovers available. ie. HSD HR front struts have 50mm shafts and a excelent quality damper. At $1799 for a full set of 4 they are excellent value.

Cheers,
J.

Thanks for the info cruzida, I will definatly look up that thread.

I have access to a mill so I may have a go myself. If nothing elce it will be good experience for future projects and I may be able to iron out the bugs before I get the final items CNC machined.

As for getting 10 made up, that might not be a bad idea, I allready have 2 other guys localy, interested in similar setups, and I am sure I could sell the others on this or the ae86drivingclub forums. Anyone interested let me know, as I would be quite happy to sell them at no profit to help fellow toyota fans out.

i could be keen on a set of front brackets, as i have some CA18DET calipers and discs gathering dust (already have a rear disc setup ready to go on a T series)

will you be going floating disc? (as per standard S13 stup)
