I kinda think it may be a bump stop issue. I'm putting only light pressure on them in these pics. Below is one from post #30 where it looks like I had more pressure on, with the test wheel somewhat higher. What's interesting is the ball joint angle. I had the boots off since it was assembled just for testing. The angle looks "unhealthy". I wonder if a lot of the lowered cars are running angles like this. Perhaps they survive OK like that I don't know.
There's also a pic showing the wheel at max droop.
The good news is I think I found the upper limit of tire size in terms of height. This is a 225/50/15 which is almost 27" tall. I was surprised a tire this tall is functional. With the steering linkage connected, they do not hit the frame. At max droop there is only 1/4" clearance to the frame with full left turn, and there's also about 1/4" clearance to the front of the fender. The upper fender lip clears with the "light bump stop pressure" position. Going higher not so sure yet. Maybe with fender rolling.
