For me, I can feel the weight distribution of the car VERY well in AC, but much less so in pcars. I use both a G25 and a T500, and both work well (obviously more overall force in the T500, but in both wheels the effects are there and are excellent). Try something where you should *really* feel the weight, like the Yellowbird. I can tell you that the way the FFB feels in AC is very close to the way the wheel feels in a RL Porsche with similar chassis and suspension. Lift off throttle in-corner and you'll quickly feel the wheel tugging as the rear comes around - very true to life, and, IMHO, modeled better than pcars in this regard. AC also models understeer better than pcars, by a mile. In AC I can feel my wheel begin to lighten as I approach the limit of grip, whereas pcars feels more like GT6 in this regard. Not saying that pcars is bad, just saying that they do, definitely, seem to model different aspects. I mean, they've got something to work with that has, maybe 1% the feedback that you get from a real car chassis moving under you, so there will be limits. But as for the weight-transfer effects, at least in the one example where I can directly compare sim to RL, I can tell you that they are excellent in AC, so keep looking for a problem somewhere in your setup. Maybe turn all the "extra" effects as far off as possible, so you're feeling very little "road", which can definitely drown out other effects sometimes if set too high.
