Well after looking at the trailing arm thread, Maybey you whould just have them Waterjet from 1" plate:

http://dtsfab.com/index/index.php?topic=988.0

We need a picture of Enemy's setup hint hint.  He is the only one on here running rear A-arms that I know of.  His didn't seem to have a ton of gusseting, and wasn't as wide based at the frame, which IMO will add quite a bit of strenght to yours.


Ok I decided to grab some of Enemy's pictures from another thread.......   Couple crosstubes to keep anything from buckling.  No undergusseting for the shock mount....  You better ask DS what tube he used to get a baseline.

If I believe I cannot do something it makes me incapable of doing it. But when I believe that I can, then I acquire the ability to do it , even if I didn't have it at the beginning.

I'm not too sure it would save weight.

    Find out what a Tatam car front arm weighs. and a alum spindle.  That would give a good idea. 

    Or some of the engineers on this site could just figer out what crom verse's alum is.

My concern would still be the shock attachment point.

Youd have to weld that on, or water jet a hole in the arm for it to set in, then drill thru the arm for the shock bolt...

Youd still have to mill the bushing holes and stuff anyhow, Make it a bit thicker, like 1.5"

          There would be no concern. The shock attachment point could be machined in the arms.  anything in the way of 6061-t6 or 7050t351 would be supper strong.  Machining a double shock tab on the lower arm would not be a prob.

1" is 14lbs per sq ft... so 1.5 21 lbs per sq.... 36 arm 12" wide 63lbs, Less 3/4 material 16 lbs or so sound about right?

The problem with that is the expense of all that extra aluminum just to get the mount tabs integral to the arm.Another 1.5" or so of plate to buy and machine most away.
