Product main functions:
Reduce the drag coefficient, in addition to static function:
     Automotive, also known as shark fin car roof wing, the product design idea is to nature fish (including sharks) dorsal fin imitation, because fish have dorsal fin effect, can reduce the water resistance, but also can easily adjust the swimming posture. Roof-mounted shark fin fish dorsal fin function is to combine modern aerodynamics and designed product.
When the car in the air, high-speed movement, it will drag out a long vortex. When this vortex from the rear of the car, it will produce pressure drag, but at a suitable location to add a spoiler, you can force the airflow ahead of the transfer, from laminar to turbulent flow circulation, reduce friction and pressure drag, thereby reduce the drag coefficient, but also to discharge static electricity, effectively reducing the body from dust, dirt, reduce noise, etc., but also to provide some downforce to stabilize the body!

Installation method:
1, before installation please dust, dirt and other clean with a mild detergent.
2. Remove the double-sided adhesive stickers, the product will stick to the roof near the rear car window in the middle position.
