MIA's Description

It features two separate working chambers: one for the air-free hydraulic piston and valve, and another for high-pressure nitrogen gas with a floating piston. This design allows for instant, automatic adjustment to driving conditions and driver inputs, preventing fade due to aeration and providing a comfortable ride during normal driving with added performance on demand.
