Why need Splitter And Spoiler?
Both front splitters and rear wings are essential components in enhancing a vehicle's aerodynamic performance, which in turn improves handling, stability, and the overall driving experience. 
Front splitters are instrumental in increasing downforce at the front of the vehicle. They effectively minimize the airflow beneath the car, establishing a high-pressure zone above the splitter and a low-pressure zone below, thereby pushing the front of the vehicle downward. At elevated speeds, airflow underneath the car can lead to lift, which diminishes tire grip and can result in instability. Front splitters mitigate this lift, allowing for a more grounded front. Additionally, they manage airflow around the front of the car, directing air away from areas that may induce unnecessary drag.
Rear wings are engineered to generate downforce at the rear of the vehicle, thereby enhancing stability, particularly at high speeds. When utilized in conjunction with front splitters, rear wings contribute to a balanced aerodynamic configuration, ensuring that the vehicle remains stable and predictable across a range of speeds.
