How do you adjust cross weights?
If you want to add cross weight put a turn in the right front and left rear and take a turn out of the left front and right rear. On non coil over cars you may need to go two turns on the rear for every one turn on the front. By adjusting all four corners you will help maintain your ride heights.
How does corner weighting work?
Corner balancing adjusts the diagonal weight distribution (the weight that sits on each tire contact patch at rest). This means that the driver should be in the car with the fluids topped off and a proper amount of fuel in the tank to simulate race-weight conditions as accurately as possible.
Is Corner balancing necessary?
The tires bearing more weight will wear out faster. If you have installed a height-adjustable suspension, you absolutely should corner-balance the car, even if it’s just a street vehicle. If you don’t corner balance it, you have literally no idea how the weight is distributed.
How much does it cost to corner balance a car?
Even on street cars, a proper corner balance can deliver a more balanced, neutral feeling car. This can help increase performance, allow the owner to drive the car more confidently, and reduce component wear. Corner balancing packages begin at $300.
What is Corner balancing?
Corner balancing is the process of shifting the weight carried by each wheel to approach optimal values. Although some weight can be shifted between wheels by physically relocating parts of the car, the corner balance process is focused on shifting weight by adjusting the suspension spring height.
How is 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.”
How do you calculate weight distribution?
The Weight Distribution Analysis Process Multiply the center of gravity distance times the weight to get the moment for each component and item. Add all of the moments and divide by the wheelbase to get the weight on the rear axle. Subtract the rear axle weight from the total weight to get the front axle weight.
What is wedge in a dirt race car?
Wedge is defined as the difference in weight between the left rear and right rear tire. Since the left rear tire looses the most weight it is usually the heaviest corner weight on the car.
What does Wedge do to a race car?
Round (of wedge): Slang term for a way of making chassis adjustments utilizing the race car’s springs. A wrench is inserted in a jack bolt attached to the springs, and is used to tighten or loosen the amount of play in the spring. This in turn can loosen or tighten up the handling of a race car.
What does it mean when a Nascar is tight?

Why do they put tape on the front of Nascar’s?
The reason they do this is to either clean the grill to remove debris that can interfere with cooling, (NASCAR cars have much, much smaller grill openings then normal) or to add a bit of tape to reduce the opening size and help the aero of the car.
How do you make a Nascar tighter?
You can use a ratchet a turn that long jackscrew attached to the suspension in either direction to make a car looser or tighter. Each NASCAR track has its own unique characteristics that can affect a car’s handling.
What does tape and wedge mean in Nascar?
Wedge makes the car looser or tighter. A loose car is better on the short runs but a tighter car is better for long runs. Tape can make the car go faster. The more tape you put on your car, the faster your car will go. If you put too much tape on the car, the motor will overheat and you will begin to slow down.
How does tire pressure affect Nascar?
NASCAR tires routinely change pressure by 20-40 psi from the tire sitting on the pit wall to the time it’s run a couple of laps. So the pressure you put into the tire is no where near the pressure you have three to five laps into the race. It’s a calculated risk teams take in how low they will start their tires.
How do you tighten a loose race car?
Change rear spring rates. Softening the right rear spring, and/or stiffening the left rear spring will increase the rear roll angle and will tighten the car, as will softening both rear springs. The inverse is true, stiffening the RR spring and/or softening the LR spring will loosen the car.
What is a track bar in Nascar?
The track bar is located underneath the rear of the car. By raising or lowering the right side of the bar, a driver can alter the position of the rear axle in relation to the car’s centerline. Any changes affect the weight distribution of the car and how it moves through the corners on the track.
Is a track bar the same as a sway bar?
Track bars, correctly called Panhard bars, control side-to-side movement, which is really horizontal, not vertical. Sway Bars, correctly called Anti-Sway bars, reduce lean or sway, or roll. Track bars control the yaw (vertical axis) and sway bars control the roll (longitudinal axis).
Is it safe to drive with death wobble?
Death wobble, as I mentioned above, is a terrifying experience. Slow down immediately and, if possible, pull off to the side of the road. Otherwise, you should be able to drive it, but keep your speed under 45 to prevent death wobble from reoccurring or try driving quickly thru the 45-55 trigger point.
Can death wobble be fixed?
Something as simple as a tire’s misaligned camber or toe could cause enough vibration to trigger the wobble again. One thing many people do is install a new steering stabilizer, but this is not a permanent fix. Jeep steering stabilizers can temporarily get rid of death wobble, therefore masking a more serious problem.
