What does a spoiler do to a car?
The spoiler raises the downward force on the back of the car increasing both traction and braking ability. Even at higher speeds, drivers have an easier time braking, making driving even safer with the addition of the spoiler. Fuel efficiency can also be affected by adding a spoiler to your vehicle.
Is it a spoiler or wing?
An automotive airfoil (wing) is shaped like an upside-down airplane wing — it deflects airflow upward to generate down-force on the rear of the vehicle. A spoiler is an obstruction to localized airflow that improves the overall airflow around a vehicle.
What material is best for spoilers?
Spoilers are usually made of lightweight polymer-based materials, including: ABS plastic: Most original equipment manufacturers produce spoilers by casting ABS plastic with various admixtures, typically granular fillers, which introduce stiffness to this inexpensive material.
