Wedge adjustment can make a dramatic difference in how a race car handles during a race. Specifically, wedge adjustment refers to changing the amount of tension on a spring in the rear suspension. … These openings allow the crew easy access to tubes that go directly to springs in the suspension system.
How do you loosen up a 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 does tape and Wedge do in Nascar?
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 does wedge affect work?
A wedge makes work easier by increasing the force applied to the object, although it applies the force over a shorter distance. This gives the wedge a mechanical advantage greater than 1.
How do you increase cross weight in a race car?
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 wheel offset affect handling on a race car?
Reduced offsets result in larger track widths. This can improve cornering speeds by reducing lateral load transfer from the inside tires to the outside tires. By keeping the tire loads uniform, tires can generate increased lateral grip. This is why most race car tires are as far outboard as possible.
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 does Wedge mean in racing?
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 does a wedge help us?
Wedges are used to lift heavy objects, separating them from the surface upon which they rest. … They can also be used to separate objects, such as blocks of cut stone.
What is the use of wedge?

What is wedge example?
A wedge is simply an inclined plane that moves to do its work. Examples include knives and anything with a blade, like scissors and saws, axes, nails, and even teeth.
What is bite when scaling a car?
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.
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.
