What does the J Bar do on a race car?
We use the J-bar to keep the rear-end of the car in the desired position. The placement of the J-bar controls several settings on the rear of the car. With it we can set the side-to-side measurement, which allows us to define the placement of the rear-end from one side or the other.
What is LR bite?
Most dirt teams refer to the amount of “bite” or “left-rear weight” in the car, which is the number of pounds of weight that the LR tire supports over the right-rear (RR) tire.
What is AB mod racing?
Modified stock car racing, also known as modified racing and modified, is a type of auto racing that involves purpose-built cars simultaneously racing against each other on oval tracks.
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 does ride height affect handling?
LOWERING the ride height at the rear of the car will shift the weight and grip to the rear. This shifts the handling balance toward UNDERsteer. RAISING the ride height at the rear of the car will shift the weight and grip to the front of the car. This shifts the handling balance toward OVERsteer.
What is forward bite?
Foward bit is straight line traction (think dragrace). Side bite keeps tires from sliding sideways in a corner. The front can push and you will not turn very well. If the rear slides you can end up spinning around.
What does the left and right track bar do?
The purpose of the trackbar is to control the left-to-right offset of the rear axle. The attachments at the left and right side of the trackbar allow for up and down motion, but not side-to-side motion. A trackbar has two mounting points – one on the frame and one on the rear-end housing.
How fast do late models go?
Late model These cars are considered to be the most sophisticated cars in dirt racing. They hit speeds well over 100 mph (160 km/h) and slide around the dirt corners. They are raced on dirt tracks throughout the country anywhere from 1/5 to one mile.
Why are drag cars lower in the front?
The main reason for a low ride height however, is for aerodynamic reasons. Lowering the ride height increases a car’s downforce without any significant increase in drag.
Does lowering a car reduce drag?
Less Air Drag There’s less air hitting the wheels and tires (that are not streamlined shapes). This makes these cars faster. Some owners of low-stance vehicles also notice improved gas mileage. BUT, lowering a car too much will actually increase wind drag.
What happens with too much caster?
Vehicles with too much positive caster can be prone to understeer, so most modern vehicles don’t have a caster greater than 3 to 5 degrees.
