I have been thinking a lot about tubular LCAs and also about the toe adjustable LCAs on this aftermarket IRS

As it stands now my current trailing arms are going to be rigidly mounted to the wishbones as I am going to weld in a second pickup off of the trailing arm to line up with the bottom shock mount for the purpose of taking said mount out of single sheer.  This got me thinking why not simply make tubular lower control arms that incorporate the trailing arm location, that I have built in to my system,  as part of the control arm.  in other words eliminates the trailing arm   all together and have the  LCA connected in 3 locations.  The following picture is a ruff example of what I am thinking of doing. 


As to the purple line I have three options there.

1.   For the sake of the pic, make it red.  in other words weld it in solid and put heim joints at the hub so I have some toe adjustment.
2.  Make the purple line an adjustable link that ties back in to the control arm, like in the picture above, so that I can easily adjust toe.
3.  Make the purple line an adjustable link that ties back in to my sub frame some where near the differential to be able to adjust toe and create a little rear steer.


Right now I am just rattling around ideas.  My current plan is to build a fixture based off of my current trailing arm and wishbone configuration that way I can put the car together with the current set up and then fabricate my tubular lower control arms at a later date.  As I am in the planning stage I would love to get some input on these ideas.  SOOOOO what do you think
