ENGINE (FUEL & TEMP) |
TOO LOW
stiffer shocks and/or springs
lower tire pressure
TOO HIGH
softer shocks and/or springs
slower entry into corner
adjust camber (front)
adjust tire pressure (see TIRE WEAR)
|

ACCELLERATION/WHEEL LOCK |
WEIGHT BIAS/RIDE HEIGHT |
HANDLING |
POOR ACCELLERATION
shorter gears
WHEEL LOCK
Road courses, short tracks - more
Large ovals - less
|
WEIGHT BIAS
ovals - more left weight
road courses - even, or slightly biased to the side with the most corners
RIDE HEIGHT
higher rake - more downforce, slower speed
even rake - less downforce, higher speed
|
UNSTABLE IN CORNERS
