Is that bent square tubing going over the front of the differential?
Yes. I have a couple of bent square pieces laying around, and would like to use them.
Where did your rear roll center land up? Long arms are good, but you may have gone a little too far. With the lower arm angled like that the suspension is effectively in a 2" bump at normal ride height.
Your upper wishbones are an interesting shape also.
Don't be discouraged, but now is the time to work out all the thinking, before you weld it up.
The RC is 2" off the ground and does not move much in relation to the center of gravity. Camber gain is ~2Deg from ride height to full compression. I am happy with those results, because if I was to make either of those values any better, I would make my swing arm length too short. I understand your concern about the long arms, but I have found better results with these lower arms, compared to with ones that were shorter, and angled slightly down, towards the wheel. Maybe I haven't explored enough options? I will work at it some more...
Don't feel that you are discouraging me. If anything, you are encouraging me to learn more, which will benefit me in the long run.
Any suggestions/criticism is encouraged...
P.S. I'm using Solidworks to figure out the geometry. I know about Wishbone, and have used it, but prefer to use Solidworks.
