Factors that cause the vehicle to oversteer
1. Unbalanced car body mass distribution: Balanced car body mass distribution should be 50:50 before and after. If the front part of the car body is smaller than the rear part (quality allocation <50:50, such as 40:60), the vehicle will behave as a turn. Excessive. If the mass of the front of the car body is greater than the rear (quality allocation > 50:50, such as 60:40), the vehicle will be understeer.
2, too low front suspension hardness (including roll stiffness, shock absorber hardness, anti-roll bar hardness)
3, too high back stiffness (including spring stiffness, shock absorber hardness, anti-roll bar hardness)
4. The front roll center is too low relative to the rear roll point.
5. The roll center is too high relative to the front roll.
