Version 1.0: First version. There ISN’T the part II of the FAQ (Parts Settings)
I: Tune Shop
Here there are all buyable parts of the game
SUSPENSIONS & BRAKES: SUSPENSIONS
Sports: An all-purpose, beginner-friendly suspension kit that covers all types
of driving, from street to circuit. Both front and rear shock absorbs
are adjustable to one of 10 damping force levels. Camber angle is also
adjustable. Clearance is lowered approximately 1 inch in the front and
back. Two-way low-pressure gas shock absorbs (adjustable to 10 levels)
Cost: 3.200Cr.
Semi-racing: A ride height-altering suspension kit for intermediate drivers.
Spring rate and the shock absorb damping force are harder than
with normal sports suspension. Front and rear ride height is
adjustable in 1-millimeter increments. Damping force is adjustable
to one of 10 levels, and camber angle is also adjustable. Single
high-pressure gas shock absorbs
Cost: 7.400Cr.
Full Customizable*: Enables tuning of all suspension parts. Adjusts shock
absorbs, replaces springs with ones with different spring
rates, and replaces the stabilizer (anti-roll bar), which
controls the vehicle’s lateral roll stiffness. Wheel camber
can be changed, and toe-in is also adjustable. Shock absorb
compression (bound) and extension (rebound) are independently
adjustable to one of 10 levels
Cost: 17,000Cr.
SUSPENSIONS & BRAKES: BRAKES*
Racing Brakes: Contains carbon metallic brake pads for dependable stopping
power, even during long-distance driving. With far more initial
stopping power and fade resistance than ordinary brakes, these
brakes are also suitable for endurance races. Brake fluid (DOT 5)
is also changed
Cost: 4,800Cr.
Brake Balance Controller: Controls the anti-lock braking system to maintain the
desired balance in braking power between the front and
rear brakes. Strengthen the front to increase
understeer for extra stability, or strengthen the rear
to increase oversteer for better maneuverability.
Remember that a too-strong rear brake balance
increases the likelihood of spinout
Cost: 11,000Cr.
ENGINE & INTAKE SYSTEM: MUFFLER & AIR CLEANER
Sports: Combines a less-restrictive replacement sports-model air cleaner with a
low back-pressure sports muffler to improve intake and exhaust flow.
Ideal as a first-time turbo upgrade. Improves high-rpm torque in non
supercharged engines
Cost: 1,700Cr.
Semi-racing: A competition-grade air cleaner with urethane sponge filter is
combined with a low-back pressure muffler designed to enhance
engine performance at high rpm. Ideal for large-displacement turbo
engines. When using with a non-supercharged engine, proper tuning
beforehand is a must
Cost: 3,000Cr.
Racing*: Delivering even better intake efficiency than the semi-racing model,
this racing air cleaner with a velocity stack is combined with a high-
efficiency straight muffler designed for racing cars that normally
operate in the high-rpm range. Suitable for tunings that maximize peak
power. Reduces low-rpm torque and so requires proper consideration of
engine characteristics, gear ratio, and other factors
Cost: 5,000Cr.
ENGINE & INTAKE SYSTEM: NA TUNE-UP
Stage 1: Boosts the power of non-supercharged engines by adjusting the ignition
and valve timing and by installing thinner head gaskets for a higher
compression ratio. The exhaust manifold is also replaced. Peak power is
enhanced without affecting low-rpm torque
Cost: 4,900Cr.
Stage 2: Picks up where Stage 1 leaves off. Not only raises the compression
ratio even further with high compression pistons and head polishing,
but
also boots high- rpm output by replacing the cams, mounting reinforced
valve springs, and Port and Polish. Although low-speed torque is
diminished somewhat, the emphasis here is on boosting high-rpm power.
The Engine Management Computer is also reset according to your vehicle
specs
Cost: 13,000Cr.
Stage 3*: Following up on Stage 2 enhancements, this upgrade completely
overhauls the engine to enhance high-rpm performance. Higher-
compression pistons, special high-lift racing cams with a large amount
of valve overlap, heavy-duty competition valve springs and connection
rods, and engine block strengthening are all part of the package. The
power band is shifted to the medium to high range to boost maximum
horsepower
Cost: 80,000Cr.
ENGINE & INTAKE SYSTEM: ENGINE
Port Polish: Polishes the interior of the intake ports, reducing air-flow
resistance boosts engine power by what may seem a low degree, but
is essential for normally aspirated and supercharged engines alike
Cost: 5,500Cr.
Full-Engine Balancing: An extensive upgrade that includes piston and connecting
rod weight balancing, and a precision balanced
crankshaft.
Reduces vibration and bearing loads, and allows higher
engine speeds. The rev limiter is reset to take advantage
of this
Cost: 12,000Cr.
Displacement Up: There’s no replacement for displacement. This upgrade raises
cylinder displacement by increasing engine bore and stroke.
Greater displacement generally boosts the engine’s torque in
all rpm ranges
Cost: 6,000Cr.
Racing Chip: The most basic upgrade. Altering the Engine Management Program
settings allows you to boost power by adjusting engine ignition
timing, the air/fuel ratio, and other variables. For turbocharged
vehicles, the air filter and muffler are also replaced, for a
beginner’s-level upgrade
Cost: 1,500Cr.
DRIVETRAIN: CLUTCH
Single Plate: Changes the clutch feeling during upshifting, so that upshifting
feels more direct than with a normal clutch
Cost: 1,800Cr.
Double Plate: This racing clutch kit features dual clutch places, ideal for
high-torque, high- power vehicles. Reduces clutch slippage during
upshifting, improving acceleration
Cost: 2,700Cr.
Triple Plate*: Featuring three clutch places, this clutch kit boosts torque
transmission and enhances the directness of the power. Ideal for
highly-tuned cars
Cost: 4,900Cr.
DRIVETRAIN: FLYWHEEL
Sports: A lightweight flywheel made with chrome molybdenum steel. Lets the
engine rev more quickly. Improves acceleration slightly, but with
narrow-powerband engines, revs may drop below the powerband unless a
close-ratio transmission is also used
Cost: 450Cr.
Semi-racing: Even lighter than the sports type, this flywheel is especially
designed for racing. Makes for a quick revving engine. Improves
acceleration slightly, but with narrow-powerband engines, revs may
drop below the powerband even more easily unless a close-ratio
transmission is also used
Cost: 700Cr.
Racing*: A super-lightweight flywheel exclusively for racing. Makes for a quick-
revving engine that also drops revs quickly. Improves acceleration and
deceleration, but with narrow-powerband engines, revs may drop below
the powerband unless a close- ratio transmission is also used and the
driver can master the proper shifting technique
Cost: 1,200Cr.
DRIVETRAIN: PROPELLER SHAFT
Carbon Propeller Shaft: A lightweight driveshaft made with a carbon composite.
Situated between the engine and the differential gear in
front-engined, rear wheel drive or all wheel drive cars,
the driveshaft is just as important as the flywheel for
acceleration performance
Cost: 3,000Cr.
DRIVETRAIN: TRANSMISSION
Sports: Replaces a normal transmission assembly with a transmission with closer
gear ratios in all five gears. Prevents revs from dropping below the
powerband when upshifting, and allows
smoother downshifts. Ensures
useful power in a variety of turns. Recommended for non-supercharged
engines
Cost: 5,700Cr.
Semi-racing: These gear ratios are even closer than those of the Sports Close-
Ratio Transmission. This gearbox is ideal for highly-tuned cars
with a narrow powerband. Note that upshifting and downshifting will
become more frequent. Because of time loss during shifting, this
transmission may be counterproductive in cars with high-torque,
wide-powerband engines
Cost: 5,700Cr.
Full Customizable*: For races that permit the replacement of all gears,
including the final drive gear. This upgrade also makes it
possible to fine-tune the gear ratios according to vehicle
specs and circuit features
Cost: 11,000Cr.
DRIVETRAIN: LIMITED-SLIP DIFFERENTIAL (LSD)
1-Way: This limited-slip activates the limited-slip effect only during
acceleration, and so is suitable for front wheel drive vehicles, which
are difficult to turn under any conditions. The absence of the limited-
slip effect during braking makes it possible to maximize turning power.
However, the tendency of the vehicle to lose stability during braking
should be noted. The shortcoming of this type of limited-slip is that
vehicle characteristics during acceleration change greatly when the
accelerator is released to decelerate
Cost: 4,500Cr.
1,5-Way: Reduces the limited-slip effect during deceleration while maintaining
the full limited-slip effect during acceleration. This ensures powerful
traction, and during braking, prevents excessive reduction in the force
of the car attempting to turn. Free of quirkiness, this is a good all-
around limited-slip unit
Cost: 4,500Cr.
2-Way: A limited-slip differential that delivers the limited slip effect during
both acceleration and deceleration. Stabilizes the vehicle attitude
during braking, thereby permitting even harder braking. Delivers powerful
traction during acceleration, but clearly makes turning more difficult
and so is suited to drivers who are skilled at turning
Cost: 4,500Cr.
Full Customizable*: This special racing modification allows independent
adjustment of the limited-slip effect during acceleration
and deceleration. Although capable of greatly changing a
car’s performance, this modification requires careful
adjustment as improper adjustment can destroy the car’s
balance
Cost: 6,600Cr.
TURBO KIT SYSTEM: TURBO KIT
Stage 1: A turbo kit that uses a compact turbocharger to generate high-rpm
torque without sacrificing torque in the low to medium range. Minimal
turbo lag and high response combine to create an excellent balance
suitable for all types of circuits. metal gaskets, oil cooler, a
reinforced oil pump, and other high-durability parts are also installed
Cost: 5,000Cr.
Stage 2: A turbo kit that stresses high-rpm peak power and low to mid-range
balance. Torque in the low range is somewhat low compared to Turbo Kit
1, but mid to high range power is boosted considerably. In addition to
metal gaskets, oil cooler, a reinforced oil pump, and other high-
durability parts, a fuel pump, injector, computer, and other turbo
components are also installed
Cost: 14,000Cr.
Stage 3: A turbo kit that focuses on quarter-mile acceleration. The powerband
shifts further into the high-rpm range than with Turbo it 2. For
greater effectiveness, this turbo kit should be combined with a close-
ratio transmission and other parts. The cam is also replaced with one
designed for turbo characteristics. In addition to metal gaskets, oil
cooler, a reinforced oil pump, and other high-durability parts, a fuel
pump, injector, computer, and other turbo components are also installed
Cost: 45,000Cr.
Stage 4*: An oversized, high-rpm, high-output turbo kit designed purely with
maximum horsepower in mind. Suitable for maximum-speed contests, for
instance. The cam is also replaced with one designed for turbo
characteristics. In addition to metal gaskets, oil cooler, a
reinforced oil pump, and other high-durability parts, a special fuel
pump, injector, computer, and other turbo components are also
installed
Cost: 85,000Cr.
TURBO KIT SYSTEM: INTERCOOLER
Sports: This air-cooled intercooler cools the hot intake air after it is
pressurized by the turbocharger. By lowering the intake air temperature,
air density is increased, allowing for more fuel to be used and boosting
power. An essential part for a high-performance turbo engine
Cost: 1,800Cr.
Racing*: Boosts the power of a supercharged engine by lowering the intake air
temperature. The larger capacity increases the temperature-reducing
capabilities but slightly lowers engine response. This high-capacity
intercooler is a suitable upgrade for engines with a high maximum
supercharging pressure
Cost: 3,000Cr.
TIRES: RACING TIRES
- Super Hard*: 10,500Cr.
- Hard: 13,500Cr.
- Medium Hard: 16,500Cr.
- Medium: 22,500Cr.
- Medium Soft: 27,500Cr.
- Soft: 35,000Cr.
- Super Soft: 47,500Cr.
TIRES: OTHER TIRES
Simulation Tires: A tire that even more closely approximates the characteristic
of actual, real-life tires. These tires make driving with the
game controller extremely difficult and so provide a virtual
experience of real-life driving (as opposed to video-game
driving), requiring early braking, careful steering, and
delicate accelerator manipulation. This is a set of front and
rear tires for paved surfaces
Cost: 6,000Cr.
Sports Tires: Sports tires are for paved-road driving and have a greater grip
than normal tires. Mounting high performance tires enhances a
car’s
cornering, acceleration, and braking performance and is the most
effective upgrade. Purchasing tires entitles you to subsequent
tire services for as long as you own those tires. Front and rear
tires must be purchased together
Cost: 6,000Cr.
Dirt Tires: Dirt racing tires, which must be mounted on all 4 wheels for racing
on dirt courses. These tires are designed to ensure vehicle
controllability on slippery gravel and other unpaved surfaces. Dirt
racing tires are available only for certain vehicle types
Cost: 22,500Cr.
STABILITY CONTROL & OTHERS: WEIGHT REDUCTION*
Stage 1: Lightens the vehicle by removing unnecessary parts and replacing others
with parts made of lightweight-material. The numerous advantages of a
lighter car include enhanced acceleration performance, improved
cornering and braking, and better tire durability
Cost: 1,500Cr.
Stage 2: Lightens the vehicle more by removing more parts and/or replacing more
with lighter materials
Cost: 5,500Cr.
Stage 3: Takes Stage 2 lightening a step further
Cost: 22,500Cr.
STABILITY CONTROL & OTHERS: CONTROLLERS
AYC Controller: This component changes the setting of the Yaw Control System,
which generates rotational moment in the vehicle by controlling
the distribution of torque between the left and ride drive
wheels. Raising the setting creates rotational moment during
cornering, for better acceleration during turns. Note that too
high a setting increases oversteer, and thus the likelihood of
tire spinning
Cost: 10,000Cr.
Variable Center Differential (VCD): This center differential makes it possible
to change the front and rear torque
distribution in a 4WD vehicle. The setting
range is 100% front/0% rear to 0% front/rear
100%. A 4WD vehicle can be made to handle
like an FF car by shifting the torque
distribution to the front wheels or like an
FR car by shifting the torque toward the
rear wheels. Torque distribution cannot be
changed while the vehicle is moving
Cost: 10,000Cr.
NON-BUYABLE: SYSTEMS
Traction Control System (TCS): This system when activated, adjust the wheelspin
(see above for more info)
Cost: 0Cr.
Active Stability Management (ASM): This system when activated, adjust the car’s
stability (see above for more info)
Cost: 0Cr.
Downforce: The downforce can be adjusted for obtain more control (increasing the
downforce) or more speed (decreasing the downforce). Many cars don’t
can adjust the downforce or only the front or only the rear. The Race
Cars and Rally Cars can adjust both front and rear downforce(see
above for more info)
Cost: 0Cr.
GT AUTO: OIL CHANGE
Oil Change: Changing the oil of your car you have a temporal increment of power
Cost: 250Cr.
