roof spoilers are an aerodynamic device which can be mounted to the roof of the car, which function to optimise air flow and promote the creation of downforce, reducing lift and drag. More downforce leads to greater traction, improving the way the car handles on the road and producing greater stability overall.
Roof spoilers are basically a streamlined panel, which can come in varying styles and shapes, designed to assist with the aerodynamics of a vehicle. Fixed to the roof of the car, roof spoilers are commonly made of fibreglass or thermoplastic.
Many car owners opt for the roof spoilers for style and design reasons but it was devised to improve the aerodynamics of a vehicle. Its streamlined shape and positioning on the top of the vehicle helps to reduce the drag of the air passing over the car when travelling, improving the lift balance between the front and rear of the car, bettering the stability and handling of the car at high speeds while improving fuel efficiency.
Although roof spoilers are designed to be rigid, strong and durable, it's a part that can be subject to damage in accidents. In the course of a lifetime the roof spoilers may need replacing due to corrosion and rust from exposure to the elements. Car body parts, such as roof spoilers, are not all compatible with all models so it's important to ensure you buy the right roof spoilers for the make, model and year of your car, ensuring that the colour will match the rest of the car bodywork.
