It seems that Amar found those vids.
I'm not sure if I should point point plenty of mistaken statements that have been done in the latest paragraphs, but I will point out something that I found last night, regarding GT4 vs FM3 suspension model:
You see, when I played GT5 and FM3 I could not stop noticing that the movement of the chasis is more noticeable in GT games, and is significantly reduced in FM, even compared to GT4 chasis movement, I can notice the tyre deforming but there is very little movement on the chasis, specially in cars like the Honda NSX in Suzuka, IRL Clarkson vid also supports this by showing the movement of the chasis in Laguna Seca on the NSX, I compare them both(in fact I compare GT4/GT5/FM2/FM3) and the movement of the chasis is really reduced on FM2, even more reduced on FM3, needless to say IRL version was closer to a mid ground between GT5/GT4, this aspect also seems to affect the weight transfer on each game because I was able to spin like Clarkson did on GT5 after going very aggressive in the last corner, and this never happened on FM(in neither).
