Vehicle Stats
There are a variety of vehicle stats that can be improved with upgrades. In the Tab menu, you can view your and other players' Performance Ratings. You car's Performance Rating is calculated based off of a combination of your car's stats.

Engine
Horsepower: Affects acceleration and top speed.
Torque: Affects acceleration a small amount.
RPM: How high your engine has to rev to make peak power. (Horsepower = Torque * RPM / 5,252)
Top Speed: Max speed without using nitrous (calculated based on horsepower and downforce).
Roll Speed: Max speed when using nitrous or going downhill (you can coast faster than your roll speed downhill if you lift off the gas).
Reverse Speed: How fast you can reverse.
Engine Health/Output: How much stress your nitrous and forced induction upgrades are putting on your engine. You need forged internals to make your engine strong enough to handle nitrous and forced induction upgrades. If this value goes below 100% you will lose that percentage of horsepower and vehicle health (I.E. 95% of 500 horsepower is only 475 horsepower and 95% of 300 health points is only 285 health points). If your engine health is above 100%, horsepower will be lost or added and you will gain in health points however many engine health percentage points you are over 100 (I. E. 105% engine health will not increase your horsepower and will add 5 health points to your vehicle health, not increase vehicle health by 5%, so 300 health points with 105% engine health is 305 health points).

Nitrous
Nitrous Boost Speed: The maximum speed you can get full boost at. If your roll speed is lower than this, your car will be more likely to spin out when boosting. If your roll speed is higher than this, your will continue to accelerate up to your roll speed while boosting but it will not accelerate as rapidly once you are past your max nitrous boost speed.
Nitrous Boost Force: The amount of acceleration that is added while boosting.
Nitrous Duration: How long your boost lasts.
Nitrous cooldown: How long you have to wait for your engine to cool down before you can use nitrous again.

Steering
Slow Steering Angle: Steering angle when driving below 3/7ths of your top speed.
Fast Steering Angle: Steering angle when driving above 4/7ths of your top speed.
Boost Steering Angle: Steering angle when using nitrous.
Front Grip: Grip/acceleration factor of the front tires.
Rear Grip: Grip/acceleration factor of the rear tires.
Axle Ratio: The final drive ratio of the rear differential.

Axles
Springs: The stiffness of the front and rear springs in the suspension.
Damping: The stiffness of the front and rear shock absorbers.
Brakes: The strength of the front and rear brakes.

Defense
Health: The amount of health your car has.
Armor: The amount of armor your car has.
Mines: The number of mines your car has.
Missles: The number of missiles your car has.
Attack: Your car's overall ability to damage other cars.
Counter: Your car's overall ability to withstand attacks from other cars.

Upgrades
You can improve your car's performance by purchasing and installing upgrades. There are a plethora of different upgrades that you can install on your car:

Performance Parts

Intakes - add a small amount of horsepower for a small amount of money

Camshafts - add a medium amount of horsepower for a medium amount of money; increases the maximum RPM that you can tune your engine to rev to in the tuning menu (RPM tuning also requires the PCM tuner or the SU Camshaft upgrade to be enabled)

Forced Induction - add a large amount of horsepower but also are expensive and put stress on your engine, reducing health and total engine output

Forged Internals - increase your engine health to withstand the stress of using Forced Induction and Nitrous upgrades

Engines - add a large amount of horsepower, but are also heavy and expensive

Nitrous - increases speed and acceleration when using nitrous, but puts stress on the engine, possibly reducing total output

Exhaust - increases the duration of your nitrous boost and adds a small amount of horsepower; enables boost duration tuning in the tuning menu

Cooling - deceases the cooldown time of your nitrous boost

Clutch - increases roll speed and acceleration

Tires - increase roll speed, acceleration, braking, and improve handling

Brakes - increase braking power, enable brake bias adjustment in the tuning menu

PCM Tuner - enables RPM tuning and boost duration tuning in the tuning menu

Suspension - allows you to adjust your suspension in the tuning menu

Driving Basics
When you are starting out with a slower car, you will have to use your nitrous boost strategically to ensure you can get over jumps and pass other players. Sometimes it is better to wait to use boost even if it is done cooling down. As you get faster, you may want to reduce your boost duration for smaller, tighter tracks so that you are able to get around corners and not understeer into walls. Once you get to about 500-600 horsepower, you will begin to need a rear wing to add downforce and make your car more controllable.

Drifting
GMR is best played with a rally car sort of driving style, meaning a mix of drifting and grip. Some corners will be faster to drift around while other will be faster to go around normally. It all depends on the track, your car's setup, and the driving conditions. Slower cars will struggle to drift so it is better to wait until you have more upgrades to start drifting. Drifting in GMR is done by boosting first, then turning into the corner while holding handbrake down, then once the slide has been initiated, lifting off the hand brake and counter steering through the corner. You will get bonus money for drifting based on the speed, slip angle, and duration of the drift.

Demolition Derbies
Demolition derbies are won by doing the most damage to other vehicles. You get money whenever you ram someone or get rammed by someone, hit someone with a missile or a mine, or when another player is eliminated.

Prestige
Once you have bought all the main upgrades in the game, you have the ability to buy prestige. This will reset your car back to stock and reset your money back to starting cash and will give you 1 super upgrade (SU) point and 2 chiptuning (ECU) points. There are 10 levels of prestige and each time you prestige you get more SU and ECU points, up to 10 SU points and 20 ECU points once you reach 10th prestige. SU points allow you to buy SU parts, which are the highest level parts in certain part catagories. ECU points allow you to tune your ECU in the tuning menu.

The tuning menu allows you to adjust various vehicle stats. In it there is a more detailed vehicle stat section with three pages. Here are descriptions for all the stats not already included in the main stat panel:

Page 1

The first page shows all stats pertaining to the powertrain of the car:

Displacement: size of your engine

Cylinders: number of cylinders in your engine

Drivetrain Efficiency: how efficient your transmission/drivetrain is at transferring power to the wheels. (This will auto-increase if the torque to weight ratio becomes too low so that slow cars can still get up hill.)

Gear Ratios: the ratio of each gear in the transmission

Page 2

The second page shows all stats pertaining to the handling of the car:

Ride Height: how high off the ground your car's center of gravity is

Total Grip: the total grip of your front and rear wheels under acceleration

Total Downforce: the total downforce from the rear wing on your car

Front Downforce: the amount of downforce on the front of your car

Rear Downforce: the amount of downforce on the rear of your car

Anti-Lock Braking System: the setting of the ABS system

Traction Control System: the setting of the TCS system

Electronic Stability Control System: the setting of the ESC system

Page 3

The third page shows all stats pertaining to the defensive and offensive capabilities of the car. There are no new stats on this page.

The tuning menu has two main sections: the chip tuning section and the vehicle tuning section.

Chip Tuning Section: requires chip tuning points to use which you can only get by prestiging.

Vehicle Tuning Section: does not require chip tuning points to use, you just have to buy the tunable part that each slider requires.

Chip Tuning
There are five different stats that can be tuned with chip tuning points:

Horsepower: Each point adds a certain percentage to your horsepower and takes away a certain percentage from your engine health depending on which forced induction upgrade you have:

• Naturally Aspirated: +0.5% Horsepower, -0% Engine Health
  
• Supercharged: +2% Horsepower, -1.5% Engine Health
  
• Turbocharged: +3% Horsepower, -2.5% Engine Health
  
• Twin Turbocharged: +4% Horsepower, -3.5% Engine Health
  
• Quad Turbocharged: +5% Horsepower, -4.5% Engine Health

Nitrous: Each point adds a certain percentage to your nitrous boost force and takes away a certain percentage from your engine health depending on which nitrous upgrade you have:

• Stock Nitrous: +1% Boost Force, -1% Engine Health
  
• Nitrous 50 DryShot: +2% Boost Force, -2% Engine Health
  
• Nitrous 100 WetShot: +3% Boost Force, -3% Engine Health
  
• Nitrous 150 WetShot: +4% Boost Force, -4% Engine Health

Nitrous Cooldown: Each point reduces cooldown time by 2.5% but also reduces horsepower by 0.5%.

Roll Speed: Each point increases roll speed by 2%.

Health: Each point increases engine health by 1%.

Vehicle Tuning
There are seventeen additional stats that can be adjusted by purchasing a tunable part without the need for chip tuning points:

RPM: Increases horsepower with slight reduction in torque and an equivalent percentage reduction in engine health. For example: if your engine revs to 5000 RPM and you add 1000 RPM so it revs to 6000 RPM then the increase will be calculated as 6000 / 5000 = 1.20 which means a 20% increase in horsepower and a 20% decrease in engine health. You can only increase RPM up to a certain amount depending on which camshaft upgrade you have and which engine upgrade you have. DOHC engines can rev higher than OHV engines.
Required part: PCM Tuner or SU Camshaft Upgrade

Axle Ratio: Adjusting the gearing in your car to be shorter (a bigger axle ratio number) will increase acceleration and help going up hill, but reduce top speed. Longer gearing (a smaller axle ratio number) will increase top speed up to certain point, but decrease acceleration.
Required part: Adjustable Axle Ratio

Nitrous Duration: You may want to reduce your boost duration on smaller tracks with shorter straights and more turns.
Required part: PCM Tuner or any Exhaust Upgrade

Downforce: Downforce gives your car increased grip at high speed, but also increases drag. Increasing downforce will help your car corner better, but reduces your top speed. Reducing downforce will increase your top speed, but will also reduce grip.
Required part: Rear Wing

Downforce Bias: You can adjust the Downforce on your car to be stronger on the front or the rear of your car. More downforce on the front of your car will reduce understeer but may increase oversteer. More downforce on the rear of your car will reduce oversteer but may increase understeer.
Required part: Rear Wing

Springs: Springs support the weight of the car's chassis. Stiffer springs will reduce body roll and increase steering response, but may make the car slide more. Softer springs will allow the wheels to conform to bumps in the road better, but will increase body roll. Stiffer front springs will create oversteer, while stiffer rear springs will create understeer.
Required part: Adjustable Coil-overs

Damping: Dampers, or shock absorbers, affect how the bouncing of the springs is dampened. Stiffer dampers will stabilize the suspension more quickly, but may make the suspension feel jittery. Softer dampers will allow more smooth suspension reactions, but the suspension will react more slowly to bumps and cornering. Stiffer front dampers will create oversteer, while stiffer rear dampers will create understeer.
Required part: Adjustable Shocks

Ride Height: Ride height will affect how high off the ground your car's center of gravity is. Having a lower center of gravity will reduce body roll and weight transfer when cornering, but can make the car slide more. A higher ride height will help the car travel over rough terrain more easily.
Required part: Adjustable Coil-overs

Brake Bias: Brake bias is the ratio of front to rear braking power on your car. Adjusting the brake bias to be more powerful at the front will result in more stability under braking, but will also create more understeer. A rearward brake bias will allow for tighter turns while braking, but will reduce stability and increase oversteer.
Required part: Any Brake Upgrade or Electronic Assist

Anti-Lock Braking System: The anti-lock braking system will help reduce lock up under braking to help you to brake and turn at the same time. A higher ABS setting will make turning while braking easier, while a lower setting will give you more raw braking power.
Required part: Anti-Lock Braking System

Traction Control System: The traction control system helps reduce wheel spin under acceleration. A higher TCS setting will reduce oversteer around corners, but may decrease acceleration and increase understeer, making it harder to drift. A lower TCS setting will allow more oversteer but increase acceleration.
Required part: Traction Control System

Electronic Stability Control System: The stability control system helps the car remain stable while cornering. A higher setting will reduce oversteer, but may create understeer. A lower setting will reduce understeer, but allow for more oversteer.
Required part: Electronic Stability Control

Low Speed Steering: The steering angle when going less than 3/7ths (43%) of your top speed.
Required part: Any Power Steering Upgrade

High Speed Steering: The steering angle when going more then 4/7ths (57%) of your top speed.
Required part: Any Power Steering Upgrade

Steering under Nitrous: The steering angle when boosting.
Required part: Any Power Steering Upgrade
