As the flagship model for Subaru, the STi packs a punch when it comes to tearing up asphalt or dirt. This is a serious, high-performance machine that requires the best in suspension to keep it glued to terra firma.

Yes, there are plenty of choices out there for Subarus…but the problem is, you have been lured by all these other incredible, slammed cars , and you secretly long for that look on your Subi.  Plenty of people out there think it’s wrong to bag a Subaru, because they think it will somehow degrade the sporty, sedan handling, or make it ride like a marshmallow. Maybe you’re worried about those dangers yourself, but that slammed stance still has you daydreaming…

Well, believe it or not, you really can have both.  Air Lift Performance has created the perfect suspension kit to tear up a racetrack, shred some back country roads, or stop people dead at a show.  As the leader in aftermarket high-performance air suspension, we know what it takes to perfectly balance ride, handling, and stunning good looks.  The engineering team involved in the design and development of these kits has over 35 years of road racing experience as drivers, engineers, and crew members. Performance is not only in our name—it’s in our blood.

So what does it take to have such a versatile suspension? It all starts with having a strong foundation.  In this case, that foundation is the struts. Air Lift uses 30-way adjustable, monotube struts—with a serious range of damping adjustment—that have been specially tuned to match the air springs. Monotube construction is the preferred choice, both in racing and for us, for its sensitivity to small inputs and its great ability to shed heat when pushed to the limit.  The 30 clicks of adjustment aren’t just for fun, but rather allow the user to dial in his preferred handling feel or desired ride quality.  The range goes from super-stiff to really soft, adjusting rebound and compression simultaneously. The struts weigh considerably less than the coil spring parts you remove, reducing unsprung weight—a benefit to both ride and handling.

Another notable feature is the presence of adjustable camber plates on all four corners. This allows for easy, precise adjustment of camber angle, making quick work of alignments for road or track.  These plates are packed with high-quality, Japanese-manufactured pillow block bearings for long life and low noise level.

What really sets these struts apart from the coil crowd is the addition of our adjustable, progressive-rate air springs.  These high-rate springs create a stable platform for aggressive track driving, while providing a level of comfort not typically found with lowered suspension systems. By using this progressive nature of air springs and maximizing available suspension travel, we can give you ta low stance without the punishing ride.  And since ride height can be adjusted with a button, no longer do you have to suffer through the curses of static suspension lowness!  Don’t deal with scraping against speed bumps or steeply angled drives; raise it up as high as the original stock height to ride off-road without damaging the underbody…and think how easy it will be to load it on the trailer.

Having good components in a kit is important, but it’s just as critical to make sure they work together effectively to produce the desired result.  Extensive testing at various racetracks has proven to be important in creating the proper handling balance…and hours of running hard at triple digit speeds in a 550hp beast certainly illustrates the toughness and durability of the parts!

That’s not all!  Before a kit makes it to the track, the components are torture-tested on our hydraulic test rig for over one million cycles, simulating a real-world 100,000 miles.  As an ISO-9000-certified company, Air Lift is committed to quality disciplines and continuous improvement in all areas.

Worried about installation?  Every kit comes with a detailed instruction manual to guide you through all the steps. If you can install suspension or wire a stereo, then you have the skills necessary to complete this installation on your own.  If you have questions or a problem, our industry-leading customer service department will take good care of you.

The time has come.  Stop making excuses.  Haven’t you waited long enough to have it all?
