Hotchkiss Leafs Installed
Yes, as GT pointed out my Challenger has a bigger stock bump steer issue than A bodies do, by virtue of the e-body suspension being used as the same platform for all the station wagons. They ended up with more anti-dive etc built into the design to handle the MUCH heavier station wagons.
The frame attachement points don't change with the drop spindles. But, because you move the "axle" on the spindle upright, you increase the distance between the "axle" and the outer steering arm attachment. This in effect lowers the outer steering arm attachement, as the wheels are the same. So, with the drop spindles the upper and lower control arms take on a more stock appearing angle, much closer to design than a severely lowered stock suspended car, raising the roll centers etc. But the tie rods end up with more angle.
You can see it in the computer model here, the thing that you have to keep in mind is that because the wheels aren't located in the same place on the spindle, both of these models end up with similar ride heights, even though it looks like my car has been raised. I added in the orange lines to show the axis point of the wheels. Its not to scale, but it gives a little more perspective on what you're looking at. The magenta looking lines below the LCA are in fact the steering arms.
You can also compare the stock spindle (top) to the drop spindle (bottom). Since the wheel is still the same height, and has to sit on the ground, you basically lower the outer steering arm attachment point by 2".
