Garage - Chassis

The player can select the chassis or body style that is used to build the vehicle. The chassis is the basic structure of the car that includes the body design, placement of components, placement of tires, center of gravity location, and the basic aerodynamic properties. The user can choose from any of the cars and modify its attributes so that it conforms to a particular class or style.

Center of gravity: The center of gravity (CG) is the location where, if suspended, the car would rotate. The center of gravity affects both the static weight placement and how weight is transferred over acceleration. Generally, the lower and more forward the center of gravity, the less weight is transferred to the rear. In drag racing, the ideal setting would be the one that allows all the weight to be evenly transferred to the rear with the front tires just barely leaving the ground. This will eliminate the rolling and inertial resistance of the front tires and guarante that all the weight is on the rear tires.

Wing: The vehicle's aerodynamics greatly affect top end perfomance. Each vehicle has different aerodynamic properties. Frontal area and drag factors are based on the design of the car and can't be changed by the user.

Wings are added to the chassis to provide an adjustable means to keep the car glued to the ground with the greatest amount of pressure on the driving tires. The size and angle of the wings have the largest effect.

All chassis can be equipped with a rear wing. Only some cars can have front wings. The following items can be edited for each wing:

Elements: Specifies the number of wing elements. Multiple elements typically give higher downforce with less drag.

Width: This is the width of the wing. It should be thought of as going in the same direction as the car's width.

Chord: This is the front-to-back size of the wing.

Angle: This is a measure of the angle the wing chord makes relative to horizontal.

Endplate: An endplate is a vertical plate attached to the edges of the wing. The endplate helps keep airflow from spilling off the side of the wing and helps increase downforce with little iduced drag.

Wheelie Bar: A wheelie bar is a bar attached to the rear of the chassis that helps keep the vehicle from flipping over backward. Any chassis can have a wheelie bar attached.

Wheelie bars can be customized to give the car lift and balance in a desired way. The parameters that determine the characteristics of the bar are:

Style: The bar can be a single or double bar. A double bar will provide more strength and stability.

Length: This is the length of the bar in inches from the attachment point of the chassis.

Static Height: This is the height off the ground when the car is at rest.

Stiffness: This is a measure of the stiffness of the bar. Think of the bar as a spring. The stiffer the bar the more force the bar will apply to the chassis.
