Would you like to know more about what happens every time you change a parameter in your NASCAR car? NASCAR The Game: 2013 showed a label which describe the usefulness of each parameter into tuning screen, but it was inexplicably removed on NASCAR '14. Here you can find its contents again.

Post Scriptum: If you need to know something more about setups, I suggest you to read the Beginner's Guide from K Steinwand.

The overall weight of the vehicle never changes. However, teams can transfer weight to different areas of the vehicle. Adjusting the distribution of weight using the chassis affects the vehicle's balance and handling. Teams create light chassis and use metal weights that add ballast to the vehicle. Altering the balance and weight of a vehicle can tailor a vehicle to any team's needs.

Wedge & Bias

• Front Bias - Adjusts the weight toward the front of the chassis. More front bias tightens the chassis when entering a corner under braking.
  
  
• Left Bias - Adjusts the weight toward the left of the chassis. More left bias loosens the chassis when making left hand turns.
  
  
• Wedge - Increase wedge to tighten up the chassis, or decrease to loosen up the chassis.

Front & Rear Sway Bar

• Front - Increase front sway bar diameter to reduce body roll and tighten up the chassis.
  
  
• Rear - Increase rear sway bar diameter to reduce body roll and loosen up the chassis.

The drivetrain and aero comprise several different areas of the car, but noth can be altered to fine-tune performance. These areas can be tweaked to compliment the changes made to the rest of the car.

Gearing

• COG - Type A provides slightly better torque and fuel mileage, and Type B provides quicker acceleration but a slightly lower top speed.

Brakes

• Bias (Front) - Adjusts brake pressure toward the front to tighten the car under braking.

Steering

• Steering Lock - Controls how far the wheels turn, adjusting the amount the front wheels can turn under steering input.

Aerodynamics

• Grill Tape - Adding tape increases the air flow over the splitter, enhancing its effect.
  
  
• Front Splitter - Adjusts how far the splitter extends from the bodywork. Higher setting improve front end downforce, loosening the car.

Stiffer suspension makes the car quicker to react to steering inputs, while a softer suspension can result in a more controllable car when driving over the limit. If the suspension is too stiff, it can cause the car to lose traction over bumps and become hard to handle. Suspension that is too soft will mean the car will suffer from excessive body roll and handle sluggishly.

Front Left

• Ride Height - Adjusts ground clearance at this corner. More front left clearance will decrease wedge, loosening the chassis in left turns.
  
  
• Bump - Stiffens or softens the front shock during bump. Higher (stiffer) settings tighten the car in corner entry, but loosen on exit.
  
  
• Rebound - Stiffens or softens the front shock during rebound. Higher (stiffer) settings tighten the car in corner entry, but loosen on exit.
  
  
• Spring - Adjusts how the car reacts under acceleration and braking. An higher setting (stiffer front springs) will make the car tighter.

Front Right

• Ride Height - Adjusts ground clearance at this corner. More front tight clearance will increase wedge, tightening the chassis in left turns.
  
  
• Bump - Stiffens or softens the front tight shock during bump. Higher (stiffer) settings tighten the car in corner entry, but loosen on exit.
  
  
• Rebound - Stiffens or softens the front tight shock during rebound. Higher (stiffer) settings tighten the car in corner entry, but loosen on exit.
  
  
• Spring - Adjusts how the car reacts under acceleration and braking. An higher setting (stiffer front springs) will make the car tighter.

Rear Left

• Ride Height - Adjusts ground clearance at this corner. More rear left clearance will increase wedge, tightening the chassis in left turns.
  
  
• Bump - Stiffens or softens the rear left shock during bump. Higher (stiffer) settings loosen the car in corner entry, but tighten on exit.
  
  
• Rebound - Stiffens or softens the rear left shock during rebound. Higher (stiffer) settings loosen the car in corner entry, but tighten on exit.
  
  
• Spring - Adjusts how the car reacts under acceleration and braking. An higher setting (stiffer rear springs) will make the car looser.
  
  
• Trackbar - Raise the trackbar to loosen up the car, or lower to tighten up the car.
  
  
• Rubber - Adding a rubber to the left rear will tighten the car. Removing one will make the car looser.

Rear Right

• Ride Height - Adjusts ground clearance at this corner. More rear right clearance will decrease wedge, loosening the chassis in left turns.
  
  
• Bump - Stiffens or softens the rear right shock during bump. Higher (stiffer) settings loosen the car in corner entry, but tighten on exit.
  
  
• Rebound - Stiffens or softens the rear right shock during rebound. Higher (stiffer) settings loosen the car in corner entry, but tighten on exit.
  
  
• Spring - Adjusts how the car reacts under acceleration and braking. An higher setting (stiffer rear springs) will make the car looser.
  
  
• Trackbar - Raise the trackbar to loosen up the car, or lower to tighten up the car.
  
  
• Rubber - Adding a rubber to the right rear will loosen the car. Removing one will make the car tighter.

The tires affect how well the power of the engine is transferred to the road. When the pressure of the tires is increased, performance will also increase over a short distance. However, performance will suffer over longer distances. For this reason, qualifying setups often run with high tire pressure because they only have to last a short distance.

Front Left

• Cold Pressure - Adjusts handling characteristics. Higher front left settings increase spring rate, reduce grip and will tighten the car.
  
  
• Camber - Adjusts the tire's angle to maximize the contact patch on the track. Excessive camber may reduce grip and increase tire wear.
  
  
• Caster - Provides directional steering stability. Higher settings loosen the chassis the more the wheel is turned through a corner.

Front Right

• Cold Pressure - Adjusts handling characteristics. Higher front right settings increase spring rate, reduce grip and will tighten the car.
  
  
• Camber - Adjusts the tire's angle to maximize the contact patch on the track. Excessive camber may reduce grip and increase tire wear.
  
  
• Caster - Provides directional steering stability. Higher settings loosen the chassis the more the wheel is turned through a corner.

Rear Left

• Cold Pressure - Adjusts handling characteristics. Higher rear left settings increase spring rate, reduce grip and will loosen the car.
  
  
• Camber - Adjusts the tire's angle to maximize the contact patch on the track. Excessive camber may reduce grip and increase tire wear.

Rear Right

• Cold Pressure - Adjusts handling characteristics. Higher rear right settings increase spring rate, reduce grip and will loosen the car.
  
  
• Camber - Adjusts the tire's angle to maximize the contact patch on the track. Excessive camber may reduce grip and increase tire wear.

Front Toe Adjustment

• Front Toe-in - Turns the tires in or out at the front. Too positive (toe out) will make the car turn slower into a corner, and handle tighter.

Rear Toe Adjustments

• Left Rear Toe-in - Turns the tires in or out at the rear. Too positive (toe out) will make the car turn slower into a corner, and handle tighter.
  
  
• Right Rear Toe-in - Turns the tires in or out at the rear. Too positive (toe out) will make the car turn slower into a corner, and handle tighter.
