Hi all, Ive studied Skipbarber's pushrod's spindle, body, inboard and outboard explanations and i think i understand about the coordinates relative to the rigid bodies but am wondering about their placement within the car. from what i see from Spkipbarber's hdv file is that the rear spring damper is almost horizontal with the chassis of which length of spring/damper to be 29 mm. PushrodSpindle=(-0.12,-0.14,-0.05) // spring/damper connection to spindle or axle (relative to wheel center) PushrodBody=(-0.413, 0.1100455,-0.05) // spring/damper connection to body (relative to wheel center) where as isi's NSX. the Push rod body is 2m vertical as seen below: PushrodSpindle=(0.02,-0.12,0) PushrodBody=(0.02,2,0) Would like to understand: 1. why the discrepancy of the spring/damper locations between the cars, in particular the nsx's pushrod body position at 2m seems so wrong but works well in game. 2. Am im guessing what each function does correctly? or am i missing something here? im wondering as well, being the spring damper locations having mechanical properties, how come this parameter is not within ptool? thanks for reading!
