How does cross weight work?

In circle track racing, the use of the term “crossweight” gives us an indication of the weight distribution on the four tires. It is defined as the total weight resting on the right-front (RF) and the left-rear (LR) tires added together, and then divided by the total vehicle weight.

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 do you calculate cross weight percentage?

To calculate cross-weight percentage, add the RF weight to the LR weight and divide the sum by the total weight of the car. Cross-weight is also called wedge: If the percentage is over 50 percent, the car has wedge; if below 50 percent, the car has reverse wedge.

How does weight affect car performance?

The heavier the vehicle is, the more energy it needs to get moving. Heavier vehicles have greater inertia and greater rolling resistance, which both contribute to increased fuel consumption. Reducing weight is a very effective way to improve a vehicle’s efficiency (RMI 2011).

Where should the weight be in a car?

For best traction you want a greater percentage of the vehicle’s weight centered over the drive wheels, the wheels where the engine sends the power to propel the car. Basically: Do add weight in the back of a rear-wheel-drive vehicle. Don’t add weight to the back of a front-wheel-drive vehicle.

Why do car corners weigh?

Why Should I Corner Weight My Car? Within many motorsport categories, corner weighting a car before an event is crucial due to the large affect it can have on the lap times and capabilities of the car. It can significantly increase lap times and make the car feel much more predictable for the driver.

How do you adjust corner weight?

To add weight to a given corner, raise the ride height at that corner or lower the ride height at an adjacent corner. For example, if your initial setup is 52 percent cross-weight, and you want 50 percent cross-weight, lowering the right front or left rear corner will decrease cross-weight percentage.

What is Corner balancing a car?

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.

What does Wedge mean in racing?

Wedge, or cross weight, is the total weight of the RF and LR corners divided by the cars total weight. It is used to keep the back of the car tight entering a corner while also adding bite exiting a corner. Wedge is required to get through the corners.

What is wedge in a dirt car?

The tire at the rear on the left loses the greatest amount of weight, and the difference in its weight compared to the right-hand rear tire is known as the wedge. If the wedge is too high, then that means the left-hand rear tire is too heavy, and the car will not handle well as it’s steered through the corner.

How do you get more forward bite in a sprint car?

Re: Forward Bite – Wing Sprint Car

Over rotating in corners, and loosing alot of speed in corners. then you start to catch up going into corner. All still applies, as far as what to do! To improve cornering raise car, reduce stagger, decrease LR rebound, add RF plus 1/4 or 1/2 turn for more wedge.

How do you calculate front/rear 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 net weight vs gross weight?

Gross Weight is the total weight of a shipment of goods, including their packaging such as crates, pallets etc. Nett Weight is the weight, or mass, of the goods themselves without any packaging. Tare is the weight of packaging or a container without the goods.

What is rear bite?

The rear bite number appears to be the weight of the LR minus the RR. When reviewing my data I noticed I have over a 20 lb spread on the rear bite number. These are all at the same overall weight (350 lbs) between a few different karts. I hang 70 lbs to make weight.

Why do heavier cars go faster?

Weight affects speed down the ramp (the pull of gravity), but it’s the mass (and friction) that affects speed after a car leaves the ramp. Heavier cars have more momentum, so they travel further, given the same amount of friction.

Does weight really matter in cars?

Weight is important when two vehicles collide. The bigger vehicle will push the lighter one backward during the impact. That puts less force on the people inside the heavier vehicle and more on the people in the lighter vehicle.

Is 200 hp enough?

The same applies for an automobile. To break it down in quarter-mile drag racing, every 100 lb removed from a vehicle equals [approx.]

How do you add cross weights?

To raise the cross weight, you can do one or all of the following:
  1. Decrease the turns in the left front torsion bar stop (removing weight from the left front).
  2. Increase the turns in the right front torsion bar stop (adding weight to the right front).

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.
