Hint: Drift mode:

In drift mode, set your car up using the following this basic structure. Tune the ECU to have as much torque as you can get in the early gears. Make all of the suspension settings as hard as possible to eliminate shock travel. This will help get the back end out. Turn the tire grip to weak. Also, make the cars acceleration as quick as possible. For the toe settings, lower it all the way. Make the aero settings as weak as possible. Set the brake bias towards rear. By doing this, you will greatly increase your score, especially on the downhill. On the straight-aways you can do Choku-Doris (go from side to side) to rack up big points. You can then link them to power over-steer drifts, which is when you will use the torque and acceleration to lose traction in the back tires, then use carefully timed throttle control to get around the corner as sideways as possible. This will help your drifts scores get as high as possible. Throttle control is very important -- do not get discouraged if you spin out a lot. Note: This has not been attempted on FF or AWD cars. FF and AWD cars will most likely have a softer suspension setting but everything else would probably remain the same. FF and AWD cars also need the hand brake to initiate drifts more than a FR car would.
