What does lowering the track bar do?

Raising the track bar makes the car looser (oversteer) and lowering the track bar makes the car tighter (understeer). In a turn, a car transfers weight from the inside of the car to the outside of the car due to centrifugal force.

How do you increase side bites in a dirt track car?

To give the car more lateral traction, go to a softer right rear bar or a stiffer right front spring. A stiffer left rear bar will have two effects: raising the car (higher CGH), and adding static left rear weight.

How is ride height calculated?

Answer: Ride height is the space between the base of your tire where it touches the ground and the underside of your vehicle.

How does ride height affect handling?

For a higher ride height, the center of mass of the car is higher, which makes for less precise and more dangerous handling characteristics (most notably, the chance of rollover is higher). Higher ride heights will typically adversely affect aerodynamic properties.

What kind of suspension does Nascar use?

NASCAR will be moving from a solid-axle rear suspension to an independent rear suspension for the first time in history.

Why are track bars adjustable?

And an adjustable track bar allows you to correctly position the axle after making any suspension height changes. If you run 6” lift coil springs and decide to change over to 8” lift springs, then an adjustable track bar will allow you to easily correct the axle position and retain proper vehicle drivability.

What does left side weight do in a dirt car?

Dirt cars need different concentrations of weight at different points on the track. Going into the turn, left-side weight should transfer to the right-side tires to produce side-bite, which makes the car take a set (stop sliding).

How is left rear bite calculated?

Subtracting the amount of weight supported by the RR tire from the LR tire’s weight, we arrive at a number and call that the amount of bite in the car, i.e., “100 pounds of bite or left rear.”
