So many variables. Take my situation, I'm very space limited. On top of that there are so many designs, unique IRS designs. I'm not saying it couldn't be done. The base line would have to always start with the IRS Carrier unit itself. Needed to drill down on specifications. IRS Unit/Chassis Dimensions/Use, Street, Race, Show, Etc.../????.
I understand where your going with this. It's taken some time to understand the whys. For example just moving the brakes inboard and how it effects geometry needs or wants. Wow! Everything is so purposeful and that's what a newbie may have a hard time grasping. I still find my knowledge still limited.

Hi Ralphy ,
I agree it is a a big project but look at the locost projects, pretty much the closest to an open source car, the IRS assembly unit is way simpler than that , sure the are variations but a flexible base line would be the aim.
Ralphy I agree the carrier unit is key, either an OEM base carrier or an aftermarket eg Dutchman have very inexpensive 9" based carrier unit.
The hub carriers are also key, corvette C4 are the popular option and certainly proven geometry.
I believe the control arms are the difficult part as they are the parts that provide the flexibility to cater for different widths.
Also in this category is the Axle shafts whether CVs or yoke style. Again different sizes to suit different width and HP output.
Comments ?
Cheers

Without micro-managing anyone's work effort, I don't know that we can really provide anything but guidance even with more specific and detailed information.
Like most IT decisions/projects, the best information can be put out there, but the implementation is still an exercise left up to the reader/user/builder...
Hi There,
Indeed I agree, but if you take the anology of making a cake.
You know what the ingredients should be and roughly how to make it eventually you'll bake a great cake.
What I'm advocating is a recipe , you can still change it to your individual taste but you have known starting point.
Does this make sense?
Cheers

My first thought before I even noticed your from is it OZ/AUS?
Was this link.
The guidelines however only cover the Jag IRS which is the last pdf. Maybe you have seen this before.
Ralphy
hi Ralphy,
Yep seen that link infact if you are building a rod or custom in Australia this is the "bible"
However it only provides guidance, as far as I'm concerned I wouldike more speciific information, drawings, dimensions and othe best know methods.

Patrick -
I did something similar with a DIY CNC group a few years back. It was more of a "open source Design" effort.
Guess because I jumped in with both feet and offered a number of ideas, concepts and planning precepts - I got "voluen-told" (new age term for "volunteered") to lead the effort.
I think you have a great idea, and I'm happy to participate . I suggest you'd make a great leader for it with your IT experience. How would you like to approach it - online as part of the forum, a set of separate sub-threads - Like Planning Your IRS, Design Considerations, Software Aids and Resources, Hardware Alternatives, Installation, Testing/Drive and Performance, etc?
Daze is the "mufta" for this forum, and maybe he could break out a separate thread?
-- Or Maybe just create as we go, but include in theThread Title - the appropriate category (my examples above) as first line --- then someone could search on the prefix and get all the info they need at once. Keeps the forum flowing and allows for a "library" for later use as you mentioned.
There I go again, I type too much -- even though I only use 2 fingers!
BTW - where in AUS is home? I spent most of my time (2 years) in QLD. Cairns, Bundy, GB Reef, then went over the top and left via Darwin.
Cheers - Jim
Hi Jim,
Great to hear from you. firstly Jim, I'm from Melbourne.
And secondly great to have you on board.
My thoughts about submitting contributions is that we could do it with a few threads.
The idea would be to firstly break up the project into different assemblies, request contributions for the assembly, vote on the submissions and "lock in" the assembly into the design.
Then the real work starts, design , fabrication.
What do you think?

Hi Guys,
This is a great forum, the amount of knowledge that I have picked up from reading the posts, looking at the pictures has been invaluable in my quest to complete my 48 Chevy. Passenger project.
I would like to propose that given all the knowledge from fellow members we would be in a great position to develop detailed specification for the installation of 1 or more IRS configurations.
I'm in the IT game and "open source" movements through out the industry have produced many useful pieces of software that have been developed by volunteers, enthusiast and professionals to allow acces to the programs by making the software freely available. Just google "open source "
My idea for the open source iRS would be to define specifications that could be used by people like us in their IRS installation.
In other words a Recipe for installing an IRS .
As other open source projects and indeed as most car projects are different users using the recipe for their installation can and could contribute to the project by documenting their specific variances to the original recipe. Thereby ending up with a library of known installations.
Think of it this your car project would a have a virtual history as well as a physical history.
Anyway this is a discussion any comments.??
Cheers and have a great Christmas and a happy new year..
Regards
Patrick

HI Slammy,
I'm building a custom chev48 IRS, I have looked at most options. Heidts kugel etc. but all of these are at premium price.
one of the option that I'm quite interested in is from team321 www.team321.com
this approach is fairly cool. and uses a standard ford lincolm pumpkin and standard S10 hubs with custom A Arms and coilovers.
I was interested on building something similar using a Chevy Camaro lsd diff. Biggest issue was manufacturing the hub carriers. Hence why I went out and purchased a Jag IRS.
The biggest issue that I'm finding with the JAG IRS is that there is a lot of searching required to find the right ratios, LSD , upgraded rear brakes, bearings etc, lets face it these things are over 20 years old and technology has certainly moved on.
My plans is/was use a camaro diff centre with CV's and mate them to the Jag hubs using a similar adaptor to yours, or see if the s10 hub carriers can be fitted into the Jag hubs.
I will be measuring this combo over the weekend.

HI Slammy,
Looking at the adaptor that you made, do you think a similar adaptor could be made for the hubcarrier end?

Hi Guys,
Is CWI still in business??, their website is not coming up and I have tried to call with little luck.
I would be a real shame to lose these guys!

HI Slammy,
Great stuff, I have heard that the front chevy hubs from a late model 4wd will work.
I can't see relative dimensions on the picture and it may be a dumb question what is the new wheel travel.?

Hi All
Ol48 here, great site daze!, a wealth of info.
I'm in the process of building my second 48 chev ute in Australia.
After months of research, decided to go with a JaguarXJ6 series 2 IFS and IRS on the old gal.
I'm in the process of preparing the frame for the mounting of both ends, pictures as soon as I remember t o take camera to workshop. !
