thanks for the reply lordpantsignton. I found these two threads which offer some clues (below). Need to process them a bit more and look at the files to know for sure. http://isiforums.net/f/showthread.php?t=259 Getting the suspension and wheels to move in unison http://isiforums.net/f/showthread.php?t=21237 Suspension / spindle problem I gather that the graphical animation can be a bit limited which leads me to believe the game wouldn't be capable of positioning the graphical wishbones accurately from full droop. Although I suspect you'll likely have much better success with a traditional a-arm suspension rather than a rocker type mentioned in the thread. I'm getting close to this step so I guess I'll know soon enough. BTW: When you say "uni-ball joint" are you referring to a point half way between the two inboard pickups? Basically the rotation axis for the kinematic curve on each wishbone? It appears that the suspension on each corner, including both upper and lower wishbones, would only have one pivot point unless they can somehow be in two separate gmts. If it can only be one gmt per corner I'd choose the top wishbones rotational axis over the lower to move both since it would be more noticeable (assuming that's the proper pivot placement). It sounds like there will be some compromises with whatever method but fortunately my suspension won't move much. May have to look closely at the legends era cars to see how their suspension arms move in game. May provide some clues. If anyone has sorted this already your insight would be greatly appreciated.
