Description

This spoiler rectifies the flow of air from the front to the side of the vehicle and improves driving stability. It controls the flow of air under the vehicle body and prevents it from lifting the vehicle by diverting it toward the rear. It was designed under the assumption that the already available front under spoiler is also installed on the vehicle. These parts deliver optimal performance when used in combination.
