- SUSPENSION
SPRING RATIO
Adjust the hardness of the springs.
The stiffer you make the springs, the faster and more responsively the car steers.
However, over-stiffening the springs makes the car very unstable on rough roads.
Some courses have smoother roads than others -- the smoother the road,
the stiffer you can make the springs.
RIDE HEIGHT RATIO
Adjust the height of the car.
Lowering the car's height lowers its center of gravity and makes it more stable on the road.
However, over-lowering the car causes it to bottom out,
which means you can completely go out of control following a jump or particularly vicious bump.
This can be balanced by increasing the spring ratio and damper ratio
but race the track continually while adjusting to ensure maximum balance for each particular track.
Again, the smoother the track, the lower you can adjust the car.
DAMPER
Adjust the decreasing strength (dampening ratio) of the damper.
The softer the dampers, the more the car rolls into corners and over-reacts to bumps in the road.
The harder they are, the more unstable the car gets out of corners.
Some of the lighter cars have problems getting their power down cleanly on the road
their tires spin and the car shakes. By softening the dampers, the tires are able to grip better
the down-side is that the body roll is over-exaggerated through corners.
When this happens, adjust the Spring Ratio and to lessen the effect.
CAMBER
Adjust the negative camber angle.
This makes little difference to overall performance, and setting this wrongly can completely
ruin the car's handling, braking and steering.
A slight tweak negatively increases the car's stability through corners,
but this is offset by loss of braking ability and steering effectiveness.
In most cases, it's best to leave this as is.
STABILIZER
Adjust the roll rigidity of the stabilizers.
The stabilizers affect the car's cornering ability by making it more stable.
Over-adjusting the stabilizers causes the car to become over-reactive on the straights.
Under-adjusting makes it roll through corners and become very unstable.
Just remember -- the car's stability is also directly affected by the dampers and spring ratio --
so adjust this in relation to the other two.
BRAKE
Adjust the brake balance front and back.
The more powerful the brake setting, the more the car's weight is thrown forward during the
braking process. This can cause real handling problems if you brake while turning. Basically,
the more powerful the front brakes,
the more the car understeers (that means it wants to carry on in a straight line)
and the more powerful the back brakes, the more the
car oversteers (the back wants to slide around).
The latter condition is more preferable because it helps the cornering effort,
but can cause a loss of traction. Tweak the brakes to suit your driving style,
starting with the rear brakes first.
- ENGINE
TURBO BOOST PRESSURE
Adjust the turbo boost pressure.
The higher the setting, the higher the peak power is raised, but this detrimentally affects
the low-down acceleration is affected.
Generally speaking, you want to have turbo pressure at maximum,
unless you're driving a course that requires strong low- and mid-range acceleration
(such as Special Stage R11).
GEAR RATIOS
Adjust the ratio for each speed gear.
Lowering the final drive ratio reduces the car's acceleration, but enables it to reach faster speeds
(idea for a top speed test, for example, or very high speed courses).
The higher the final drive, the better the acceleration,
but it lowers top speed. Adjusting each individual gear ratio enables you to ensure that the engine
revs are always kept in the car's power band.
This is particularly important for turbo cars where the power band kicks in at higher revs --
by not keeping the revs in the power band results in very poor pickup,
reducing the car's low- and mid-range performance,
drastically affecting the car's performance on the more twisty tracks.
- AERODYNAMICS
DOWNFORCE
Adjust the downforce.
Increasing the overall downforce (by adjusting both front and rear by the same amount)
essentially makes the car heavier, this making it more stable at higher speeds.
However, this increase in "weight" is to the detriment of top-end performance.
Lowering the downforce increases top-end performance but makes the car less stable at top speed.
Increasing the front downforce alone causes it to understeer.
Increasing the rear downforce causes it to oversteer.
- PROFESSIONAL
DOWNFORCE
There are also "Professional" items that you can buy for your
car in the tuning menu. Basically, these are for super-advanced GT2 drivers.
Although it's fine to buy this stuff, I don't recommend you use them
until you have a really good understanding of the physics of car handling.
The professional items really enable you to make serious tweaks to your car
but it's also very, very easy to completely screw up the car's handling.
So if you are going to do this, make sure you save your game before you do,
so you can always go back to where you started if you completely much up your car.
