Car Settings FAQ II

Brake Balance Controller adjustment

When you use ABS (Antilock Braking System), you can adjust the braking balance between the front and rear. Although the basic configuration matches the loading of the front and rear, it is possible to change the balance intentionally to change the handling characteristics of the car. If the front is stronger the car will tend to under steer, and if the rear is stronger the car will tend to over steer. You need to be careful because the car will be easy to spin if the rear is set too high.

Suspension

Suspension: Although the basic role of suspension is to support the chassis of the car while absorbing shocks from the road surface, in sports racing it becomes important to suppress changes is weight loading and to consistently keep the tires in contact with the road surface. Here you can choose from 3 stages of suspension including sports, semi-racing and racing. In the third stage racing suspension, you can adjust the car ride height, camber angle and toe angle in addition to replacing all the suspension parts.

This is a service that lets you adjust all the parts related to suspension. Ride height, spring rates, damper bounce and rebound damping force, stabilizer strength, camber angle and toe angle can all be set independently.

Spring Rate (kgt/mm)

Spring Rate: The reason for stiffening the springs for racing is that you want to reduce movement of the car to the front, rear, left and right while the car is moving, and also so that you can reduce the ride height as much as possible to lower the center of gravity of the car. Doing so allows you to use all four tires equally, thus improving cornering performance. However, lowering the ride height increases the risk of suspension bottoming out. You should be careful because each car has a fixed range through which the suspension can move (the stroke), and if you exceed that range the wheel housing of the body will touch the tires, or the bottom of the body will hit the road surface.

Ride Height (mm)

Ride Height Adjustment: You can independently adjust the front and rear ride heights. Although making the ride height as low as possible will improve dynamic properties of the car, if the ride height is too low the suspension stroke will be insufficient and the car will bounce as a side effect. If you lower the ride height, replace the springs with harder springs, and use other settings that are suitable for the reduced suspension stroke. You can also slightly change the front-rear weight distribution of the car by changing the balance between the front and rear ride heights.

Shock (Bound)

Shock Absorber Damping Force (Bound): This adjusts the strength of the shock absorbers as they compress (contract side). If the shock absorbers are too strong when the suspension is compressed, the suspension will be too rigid and the car will bounce.

Shock (Rebound)

Shock Absorber Damping Force (Rebound): This adjusts the strength of the shock absorbers as they expand. It is possible to make this much stronger than the contract side. As a rough guide, this should be 2 to 4 times stronger than the contract side.

Camber Angle

Camber: This adjusts the front and rear camber angles. Increasing the camber angle allows you to use the tires more effectively while cornering. If you increase the camber angle too much, it will become harder to apply the brakes. You can use an angle in the range of 3 to 4 degrees effectively without side effects. You can also change the grip balance between the front and rear tires during cornering by adjusting the front and rear camber angles.

Toe Angle

Toe Angle: This lets you adjust the toe angle of the front and rear tires. If you give the front tires a slight toe out, the steering response will be slightly reduced but the tendency to lose grip after changing the steering direction is also reduced. Toe in at the rear wheels increases the straight-line stability of the car. If you set the rear wheels to out, although this will make the car easier to change directions, in almost all cases it introduces a small amount of over steer that makes the car harder to drive. You could say that the rear toe angle has a much greater impact on the characteristics of the car than the front toe angle.

Stabilizers

Stabilizers: This adjusts the strength of the stabilizers (antiroll bars). The stabilizers suppress body roll (the car twisting to the left or right). Think of this as a spring that acts against differences between the stroke in the left and right sides of the suspension. For example, when you are braking on a flat road surface, the left and right suspension have the same stroke and so the stabilizers do not move. If you are cornering in one direction, etc, such that one side of the suspension is compressed and the other side is extended, the stabilizer acts to limit this motion. Although the stabilizers are also known as antiroll bars, because of the way they suppress body roll, you should remember that they are only ever a secondary measure for preventing body roll. The main springs are always the primary measure for preventing body roll, and the stabilizers play nothing more than a helping role. If the stabilizers are made stronger, the car will bounce even if the tires only ride up on the inside curb.

Transmission

Transmission: The transmission controls the power generated by the engine though a combination of gears. Designations such as “5 Speed Automatic” and “6 Speed Manual” represent the number of gears. The engine’s power band can be used more effectively if the gearing ratio of each gear is brought closer together. You can change the transmission here. In addition to close and super-close transmissions, you can also choose a full customization that allows you to freely choose the gearing ratios of each gear.

Full Transmission Customization

this allows you to fully configure the gearing ratios of each of the gears in the transmission to match engine characteristics and the stat of the course. You can also change the ratio of the top gear.

1st through 7th gear

Gear Adjustments: You can adjust the ratio of each gear. If the gear ratio is very low, acceleration will improve a great deal, but the gear will only reach a low speed and you will be in a rush to change gears. Take the power band of the engine and the course characteristics into account when changing these settings.

Final

Final Gear Adjustment: You can adjust the ratio of the final gear. If the gear ratio is high, acceleration will become sluggish but top speed will be increased. On the other hand if the gear ratio is too low, accelerating power will be high but the top speed will be reduced. You should familiarize yourself with the course characteristics so that you can set the best gear ratio.

Gear Ratio Auto Settings: All of the gear ratios are set automatically.
