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.
