CHASSIS EXPLANATION
A vehicle’s chassis is the main structures of a vehicle where all the other components are being assembled to the frame.
Each vehicle’s attribute were being designed to satisfy the requirements of a desired group of end users.

NORMAL PASSENGERS CARS
Being the most out of street vehicles, normal passenger cars were being formed for a few common goals and comfort is one of them. In order to achieve this, a set of street use suspension and soft spring rate will be fitted. While maintaining the level of comfort, the vehicle would be sacrificing its ride handling.
The vehicle tends to increase in body roll especially during emergency stops which contribute more forces to the front, resulting in poor steering response, stopping power and even result in accidents.
