Summary
A spoiler can influence airflow, but on a road car it is often chosen primarily for its visual finish. Its effect depends on the complete geometry of the vehicle, its position, and its speed. An added part therefore does not guarantee increased downforce or reduced fuel consumption.
What is the difference between a spoiler and a wing?
A spoiler generally extends the bodywork and disrupts or guides the flow at its edge. A wing is more often separated from the bodywork by supports to work in a distinct airflow. In catalogues, however, the two terms are sometimes used interchangeably.
Does a spoiler improve road holding?
Only tests can quantify a gain. A light decorative shape may have an imperceptible effect, while an element designed with the vehicle can modify lift and stability. A poorly positioned part can also increase drag or create noise.
Do not modify your driving style by assuming that an accessory provides new performance.
Adhesion or drilling: which method to choose?
The method depends on the weight, anticipated forces, and instructions. Adhesion requires clean, degreased surfaces at the correct temperature, followed by a respected curing time. Drilling offers mechanical fastening but exposes the sheet metal to moisture if the holes are not protected and sealed.
How to choose the right model?
Check the bodywork, year, shape of the tailgate or boot, the presence of an original spoiler, and access to the third brake light. For Volkswagen Group models, compare the references in our Volkswagen spoiler collection.
