just playing with the 4 link calc and this is what i've come up with.
i just want a singl triang setup for the rear. After a bunch of reading i have decide that a triang mid arm setup is what would work the best for me. I jsut wanted to run the numbers by some of you and see what you thought.

I would try to get the roll steer a lot closer to zero. The arms look very short as well. Can they be made any longer??

i really dont like using the arms as ramps, this is why i prefer the "mid arm" as opposed to the a full long arm setup.

Thanks

I'd untriangulate you uppers a couple inches, lower your frame lowers an inch and lengthen the links some more if you can. 32-36" c-c is a good length to ballpark the links at. shoot for 70-85% AS for a neutral feeling rear suspension and move the lower links towarads the center of the vehicle some and get it further away from the tire and it'll get hung up a lot less. Triangulating the lowers in at the frame will help with clearance, roll axis and allow some longer links.

got the AS down to 89% and the RA to 2deg

i understand AS is the back of the vehicle wanting to lift under power, but i'm not sure i understand Roll Axis fully. I cant seem to find just a simple..straight up answer.

Thanks again.
