Detailed explanation of wheel adjustment parameters of extreme racing horizon 5
Let's talk about wheel adjustment first, starting with four-wheel alignment.
First of all, camber, negative camber can enhance the steering performance of the car, increase the contact area between the tire and the ground when turning, and increase the grip.
The principle is very simple, because turning causes the center of gravity of the car body to shift, and the camber angle of the outer wheel will increase, and the negative camber angle can offset this part, so that the outer wheel can ensure the grip as much as possible when turning.
Then toe angle, a negative toe angle can make the front wheel show an outward figure of eight, while toe angle shows an inward figure of eight. The inner eight characters lead to understeer and the outer eight characters lead to oversteer. The principle is also very simple, and the angle difference between the outer wheel and the inner wheel can be increased when the outer figure is rotated.
Then there is the caster angle of the kingpin, which refers to the angle between the rod and the vertical ground, and mainly cooperates with the lateral force to provide steering positioning.
Finally, the tire pressure, tire pressure will increase the contact area between the tire and the ground, increase the tire heating speed, increase the rolling resistance, and weaken the high-speed performance. High tire pressure is the opposite.
Then there is the numerical aspect. No brainless widening is recommended, especially in toe angle. Such a little change will have a great impact. Usually, the toe angle of the front tire is changed, and the change of the rear tire is smaller than that of the front tire. The camber angle can be changed a little, but it is not recommended to be too large. Similarly, the former rotation can be changed to the later rotation.
