2015 - 2021 Subaru WRX STI
As the flagship performance model for Subaru, the STi packs a punch when it comes to tearing up asphalt or dirt. With the reputation and heritage that accompany a close involvement in the World Rally Championship for many years, Subaru owners expect their cars to perform well on any surface, in any weather. This is a serious performance machine that requires the best in suspension to keep it glued to terra firma.
Yes, there are plenty of suspension choices out there for Subarus…but the problem is, you have seen countless other incredible cars slammed to the ground, and you secretly long for that look for your Subi. Plenty of people out there think it’s wrong to bag a Subaru, because they think it will somehow degrade the sports sedan handling or make it ride like a marshmallow. Maybe you’re worried about this danger yourself…but still, that lowered stance is tempting.
Fear not—you really can have both a lowered look and unbeatable handling. Air Lift Performance has created the perfect suspension kit to tear up a racetrack or stop people dead in their tracks 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 members of the engineering team involved in the design and development of these kits have over 35 years of road racing experience as drivers, engineers, and crew members. Performance is not just in our name, it’s in our blood.
What does it take to have such a versatile suspension? It all starts with having a strong foundation. In this case, that strong 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 actually allow you, the user, to dial in your 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 the front struts. This allows for easy, precise adjustment of the camber angle, making quick work of alignments for the road or the track. These plates are packed with high-quality, Japanese-manufactured spherical bearing bearings for long life and low noise. The rear shock assemblies utilize rubber-isolated upper mounts for smooth, quiet operation. These features are part of providing a total performance package for the customer.
What 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 suspensions. By using this progressive nature of air springs and maximizing available suspension travel, we are able to ride low without the punishing ride. And since they allow ride height to be adjusted with a button, no longer do you suffer the curses of static suspension lowness! Don’t put up with any more scraping against speed bumps or steeply angled drives. Raise it up as high as stock, so you can 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 is just as critical to make sure they work effectively together to give the desired result. Extensive testing at various race tracks has proven to be important in creating the proper handling balance. After hours of running hard at triple-digit speeds in a 550hp beast, we are certain of the remarkable 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 Performance is committed to quality disciplines and continuous improvement in all areas.
