Working on my model and my suspension design today:
My plan is to use ATV spindles. They're the lightest set-up that fits in my budget. In order to get a front facing steering arm, I turned the spindles upside down. This throws a few things off in the design, but I've done my research and compensated accordingly. The only negative of my suspension is a positive scrub radius but, based on my reading, this might actually be a good thing. Car manufacturers used positive scrub radii for years to make the car easier to maneuver in parking situations.
Here is a link to my suspension:
