|January 10, 2009 - Okay, I think I have it.|
The crossmember to mount the steering rack actually has to go directly in line with the front lower control arm mounts. I can use a plate or some bars to triangulate the upper mount points to this, getting rid of my twisting problem. It's still a ladder frame with the torsion problems that implies, but a full space frame isn't going to happen at the front of this car.
I'm going to keep thinking about this, both how to implement with the lower control arms as-is and how to deal with the upper location, but I think I'm on the right track.
