Physics 4wd car rear lift under acceleration

[marty212]

as title 4wd converted a car all good but on ext view the rear lifts similar to front under acceleration instead of squatting lowering ect any one any pointers looked through subaru files ect nothing stands out? so rear suspension travelling up instead of down

Usually because of a bug in AC anti-squat calculations, only happens on some type of suspension though. Shouldn't be a problem for Subarus since they use 4 wheel macpherson struts.
