A lot of people who say this, who say there isn't a big difference between the physics/control of Forza vs Gran Turismo haven't played Forza. I own both GT4 and Forza 2, and I will tell you for a fact that Forza 2 has more realistic physics. GT's driving leans a little more toward the arcade.
With Forza, you can look at your telemetry and see how calculations are being done (did you know calculations are done 360 times per second with Forza 2?). The game is just more hardcore, it's for more hardcore racing sim type gamers. Tires have different zones taken into account -- different parts of the tires are hotter or cooler and provide different amounts of friction. Friction is properly calculated -- ie: acceleration or deceleration into a corner will /always/ affect the amount of grip you have in that corner, like real life, but that is only approximated in GT.
When you look at the telemetry, which, again, is calculated many times as often in Forza 2 than it is in GT4, you'll notice some very realistic things: the friction occilates rapidly when you are accelerating or decelerating quickly and putting the tires under significant stress.
As the physics for games like this get better, you cannot compensate for frequency of calculation. Forza 2 did 360 times per second and I believe Forza 3 is expected to do even more frequent calculations. GT4 did 30 or 60 calculations per second, with the GT5 demo doing 30/second, I believe.
At 60 calculations per second a car going 150 mph will travel more than a foot between physics calculations. That's a LOT of approximating. If you up that to 360 calculations per second, you get closer to 2 inches per calculation. And in a racing game where precision is important, that's critical.
