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 does cross-weight affect handling?

On oval track cars, cross-weight is usually used in conjunction with stagger (where the right rear tire is larger in circumference than the left rear tire) to balance handling. More stagger usually loosens the handling in left turns, so more cross-weight is used to tighten it up.

Where do you put weight in a race car?

You need to locate the ballast as close to the Center of Gravity of the car and as low as possible while maintaining the minimum total weight rule, maximum left side weight rule and car builder recommended rear weight. In other words, you want the ballast to be located in the smallest area possible.

What is side bite in a dirt car?

To the typical dirt racer, side bite is the idea that the car is rolling to the right, forcing the tires to dig into the dirt providing more traction. Like a paddle in the water, the further you push the paddle down into the water, the more force you can put through the paddle to propel the boat.

What does Wedge do 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.

What does NASCAR 5 heat tape do?

Higher tape % will increase speeds, water/oil temps, loosen the car. Lower tape % will decrease speeds, water/oil temps and tighten the car. Tape causes aerodynamic changes that have very little affect at speeds less than 140 MPH. to turn in the middle of a corner.

What is cross weight on a race car?

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.

How do you increase side biting?

Another way to increase or decrease side bite is the anti squat adjustment in the rear of the car. Adding shims to the front of the block will increase anti-squat and give less side bite WHILE ON POWER. Anti-squat only works while you are on and off the gas initially.

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 does wheel offset affect handling on a race car?

Offset and its effects

Altering offsets affect how much load each of the two wheel bearings see both in straight-line driving and during cornering. Production-based race cars like the CRX and Integra that run stickier tires and less positive offset, exhibit somewhat high-bearing loads.

How does weight affect a race car?

Weight transfer hurts overall vehicle traction. In cornering situations, weight moves off the inside tires to the outside tires. This changes vertical load on all four tires. The inside tires lose vertical load while the outside tires gain vertical load.

What is left side weight?

Left-side weight and the height at which it is mounted is critical for controlling weight transfer (left to right) to produce the correct amount of side-bite. Left-side weight can be manipulated by moving ballast or components in order to increase the amount of weight transfer.

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).

How can I reduce cross 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 are corner weights?

Corner weighting (or balancing) involves adjusting a cars suspension to achieve an even weight distribution across the diagonals of the car, and if possible left to right. However we also take into account the driver's and passenger weight to simulate how the car would be used on-track.

What is a dry slick track?

Dry slick is when the track is so dry, theres no moisture in the track to get bite and gets very hard and slick like glass, that is dry slick.

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 is wedge in a race car?

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.

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.

Is more wedge tight or loose?

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. If you want a tighter car, up the wedge ; a looser car, decrease the wedge.

What is grille tape in NASCAR?

Tape is used as an aerodynamic tool in NASCAR, as well as a repair device. If you look at pictures of the cars, you'll see the grille openings on the front. Teams will cover these with tape to improve aerodynamics and increase speed. If you watch qualifying, you'll see the openings are completely covered.

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 factor into horsepower?

Horse power doesn't matter with the weight of the car. It is the power of the engine.
