Product details
With the 2015 to 2018 Subaru WRX, STI included, air suspension makes a daily driver livable at a very low stance, and this Deluxe system adds convenience through a wireless remote and electronic switches in place of manual paddle valves. It builds on the Basic package of four struts, a Viair 444C compressor, tank, valves and gauge.
What sets Deluxe apart from the lower tiers is how it is operated. Switch inputs go to the paddle valves electrically, and the remote lets you change ride height from outside the car. Each strut offers 36 levels of damping via the supplied knob, and the air bags are sleeve-type or double-bellow depending on the original suspension design. Camber-adjustable top mounts exist on certain MacPherson-strut applications; ask a technician whether they apply here.
A quick-disconnect plug, hoses, wiring and installation manuals are part of the kit. Pro Plus and Executive versions are separate part numbers if you prefer four-corner control or auto-leveling. The 2008 to 2014 Impreza WRX STI (GRB) is shown as a compatible application, but confirm with the year, make and model checker.
Supported features
Run the air lines to the box, connect four wires to the quick-disconnect plug, wire the compressor and relay, and you are done. The included remote adjusts ride height from outside the vehicle.
36 levels of damping adjustment on every strut using the included damping knob.
Sleeve-type and double-bellow bags engineered to match the vehicle and its OEM suspension design.
Fine-tune ride height at any pressure through the adjustable lower mount.
The single 444C can raise the car from lowest to maximum height in as little as four seconds.
Available on certain MacPherson-strut applications.
