Gran Turismo 4 Cheats

When using the automatic transmission option, hold R2 to make your car remain in the same gear. This is great for remaining at a given speed through a corner, or stretching the top end of a gear for a little extra speed/performance.

To speed up your replays simply press down L3 and to turn off the background music simply press O.

To get a Blue (acceleration) and Red (brakes) Licence Test Guide simply push R3 during 3,2,1,Start. It shows you the best route to go and where to start braking. This only works on the B and A license tests and tests where there is no pace car.
