An air cup kit consists of pneumatic pistons in the form of aluminum cups, that are installed between the spring, and the top hat / camber plate of a coilover suspension system. On the other hand, will only raise your car around 3″-5″ from the lowest point you set it at on the coilovers.
When the air cups are deactivated, it returns the car to its original suspension configuration, sitting on its coilovers, thereby not compromising its geometry, handling, and characteristics. Hybrid Series is designed to raise it up temporarily to clear obstacles. They weren’t made for you to ride with air in them, or you risk ruining them. So essentially, you set the coilovers with the “parked” and “riding height” as the same, then you get to air up to avoid obstacles.
