It constitutes the heart of the game. Yellow flags are included but can be disabled. When playing in veteran and legend modes, the driver is afforded some set-up modifications. Among the tweaking available is spoiler angle, suspension, wedge, gearing and tire pressure. A help key will assist the user on the effect each setting has on his ride.
Adjustment is simply a matter of more or less of each parameter.
In essence, N2K1 for PS2 offers a watered down ride adjustment suite suitable for the probable audience for the game. This is not, nor does it try to be, a Papyrus product. As mentioned, setups can be saved. He'll then save the set-up and take a few more laps so as to dial in the right line and speeds going into corners. Finally, he'll run two qualifying laps to try and post in the top five or six pole positions.
