Adam,
You have hit on the 2 points that we found running DASD in 2013. We were trying to package the pushrod/rocker, and there was no real structure where we wanted to put things. But, we rotated the model around, and there was a straight line between the control arm and mount. Draw straight line, make a circle the size of DASD and done. As for the anti-roll devise, we had one designed, but not yet manufactured when it was time for first drive. So we re-calculated some wheel rates/anti-roll torque distribution, changed the front springs, and went testing. The car worked well enough that our drivers were always the limiting factor, so we left the extra bits off.
