htxt000: Shorter, tighter tracks require more acceleration and
better fuel economy. High speed tracks require greater
horsepower.
0
htxt001: The gears are selected based on a ratio of input speed
(from the engine) to output speed (to the tires). The
larger the value, the faster the engine will turn
relative to tires.
Gears should be selected so that the maximum amount of
acceleration is achieved when exiting corners. Top gear
should be set for fuel efficiecy.
0
htxt002: For a high speed oval use a compound that has good
stopping power but high wear rates. On a twisty road
coarse select a set with long wear times and resistance
to fading.
If you experience oversteer while braking, add front bias.
0
htxt003: Springs and Dampers (or shock absorbers) affect the way
weight is transfered and therefore the amount of force
produced by each tire. Spring rates are measured in pounds
per inch of travel. Dampers are velocity sensitve springs
and are measured in pounds per inch per second. Adjusting
springs and dampers will affect the handling
characteristics of the car.
Stiffening the front springs will add understeer.
Stiffening the rear springs will add oversteer.
Stiffening front dampers increases understeer in bumpy turns.
Stiffening rear dampers increases oversteer in bumpy turns.
Roll bars, or anti-roll bars, affect weight transfered
while cornering. Roll bars transfer weight from a
loaded tire to the opposite, unloaded tire. The Roll
Rate is the stiffness of the bar. The Roll Arm is the
distance from the bar's pivot point to the bar's
connect point. The longer the arm, the stiffer the bar.
Stiffening the front anti-roll bar adds understeer.
Stiffening the rear anti-roll bar adds oversteer.
0
htxt004: Adjust the tank size so that the minimum amount of fuel is
used to fill the tank at each pitstop.
0
htxt005: Steer Ratio is the relationship of the amount of
steering input (steering wheel) to the amount of front
wheel turn. Decrease Steer Ratio to make steering faster.
Steer lock is the angle (in degrees) that the front
wheels can turn. Increase Steer Lock to increase the
amount of steering available.
Speed Scale adjusts the amount of steer input based on
the car's speed. Speed Scale helps to reduce the tendancy
to over-correct at higher speeds. Increasing the scale
reduces steering input the faster you go.
0
htxt006: Wings provide downforce and therefore extra tire grip.
The size and shape of the wing affect the amount of
downforce and drag provided by the wing. The wing's
Length, Width, and End Plate are measured in feet. The
End Plate is the vertical piece on the edge of the wing
and has minor affects on downforce. The Chord Angle is
the fixed angle or curve of the wing and is measured in
degrees. The Angle is the additional angle of the wing
produced by rotating the wing. This angle can be
adjusted during a pit stop.
For high-speed tracks, use smaller wings for minimal
drag. On a twisty track use larger wing for higher
cornering speeds.
Wings are also used to correct handling problems.
Increasing front wing increases oversteer.
Increase rear wing to add understeer.
0
htxt007: Tire pressure is used to make minor adjustments to tire
temperature and to add small amounts of understeer or
oversteer.
Camber affects a tire's cornering force and should be set
to achieve the highest forces.
Toe affects the steer characteristics of the car and are
typically set near zero.
0
htxt008: By analyzing the telemetry data it is possible to determine
what forces are acting on the car, what the driver was doing
at the time, and how the car responded.
0
htxt009: The High Speed Oval is used for testing aerodynamic effects,
engines, and handling at high speeds.
The Skid Pad is used for testing steady state cornering and
tire grip.
The Braking track is used for testing both 1/4 mile speed
and braking distance.
The Handling track allows you to test transient handling
properties.
0
htxt010: You will typically want a different setup for each track
and each car.
0
htxt011: The Paint Shop is used to customize the look of a car.
