What do you think or am I missing something?
Off the top of my head, I THINK your upper control arm may be too short (you'd need to move the inner mounting points inboard, then lengthen the arm). (From "Chassis Engineering" :Herb Adams p.47). "In general, the upper control arm length will be between 50% and 80% of the lower control arm length... With computer analysis, it is possible to make the upper control arm length exactly right so there is little change in the roll center location...". Your roll center height may be a touch on the high side as well. (p.51) ...But a higher roll center causes jacking effects and erratic suspension movements... Most sucsessful cars have the roll center height between 1.00 inch below ground to 3.00 inches above ground..." (Most of us will probably end up at the 3" above ground end of things)
