Also, you can make a good comparison of the physics engine of both games. You get airborne too often in GT4 on the Nurb in stock cars -- but in footages that I've seen, I've never seen any remotely stock car ever take air...only race-bred machines or heavily modded street machines should be taking flight. (like the 1st long straightaway).

I have to strongly disagree here. Take any road car, go over 160 km/h (100 mph), and take that car, on soft, stock road car suspension, over a crest (even a slight one) and I will guarantee you will get at least one wheel off the ground. Changing altitude that quickly, going that fast, you
will get airborn. It's just simple physics, the car will get light at the crest of that bump, or hill, whatever, and at a relatively high speed that you can attain on the 'Ring, you will certainly get airborn, if only slightly.
As for the videos you have seen, a lot depends on why you may not have seen the cars becoming airborn. The camera angle, for one. If it isn't the same as in GT4, where it is almost at ground level after the crest, then it will not appear as if the car is becoming airborn. Also, if you have seen videos from on-board, then no, you certainly won't see the car becoming airborn, because unless you are jumping a ramp, in-car footage will not show you becoming airborn, because the amount they actually lift off of the ground is only noticeable from outside the car, or actually being in the car (the split-second weightlessness, for example).

Lastily, you gotta remember that both Nurbs aren't exactly the same. GT4s Nurb is definatley shorter.

Well, perhaps that is the case, but that is probably due to the fact that, as you said, the layout from the 1960's was slightly different than the layout from 2004. The layout in GT4 (length wise) is, I'm sure, much more accurate as, with anything, technology in this area for games has improved substantially since 1998 (despite Papyrus using GPS) PDs model is more than likely more accurate, simply due to the fact that GPS has improved since 1998, and can give more accurate measurements.
