Increase your max. speed (stats):
Go for Hill Climb, Windy Point A, which is almost a long straight with 
some turns. Try using the Toyota Tacoma.

CORR Rallys:
When doing the CORR Rallys, if the race has a bend first, wait until the 
other cars have gone then accelerate. This will get you out of the pile 
up at the first corner.

Acceleration
Accelerate about halfway down at the beginning. When you are familiar 
with all tracks, accelerate hard on the straights and brake a good time 
in advance before a turn.
