So I'm pretty certain I know at what point the suspension will bottom out, and with each revision the motion up and down becomes a bit more smooth, but I still think the UCA need to come in further.
The frame I built is sort of like having a jig that you can mount things to, and move things and tune things until you have a fluid motion. Her I moved the LCA up about 1.5", and it's created a bit of tire clearance. For the purpose of demonstrating what I'm talking about, I put a zip tie on a...
So with the LCA in the wrong position the ball joint reaches it's full travel and binds. Two remedies fix this problem. One raise the lower control arm about an inch. ( something that totally never crossed my mind. The next is creating the UCA mount straight up from the k frame to just inside...
Here is the secondary choice for where the rack can be positioned, and it doesn't require a special oil pan. Below you can see where I mounted the LCA in too low a position. I just sort of guessed since corvettes, and dusters frames are so different. I did this without the car when it was snowing.
So without copying anybody's design, I tooled around with building a coilover suspension using only part that can be bought through a wrecking yard, or auto parts store. Theoretically it should function fine if i make two upper control arm mounts that come straight up from my k frame, knock 2...
