One critical aspect that GT4 really missed for a "sim" was using throttle modulation to rotate the cars with high torque around long corners.
In a high torque car once it's settled into the corner you can simply tighten or open up your line using the throttle and no steering input. This helps the car rotate and point without using more traction out of the front tires, which if they happen to be on the limit, would cause understeer and scrub off corner speed.
And as Powder pointed out, 2mins a lap faster just isn't due to tires.
