How do I adjust the ride height and damping on these coilovers?

Ride height is adjusted using the composite spring perches on the strut body. Rebound damping is adjusted via a knob on the top of the damper, offering 16 distinct clicks to change the firmness of the suspension.

What is the benefit of the composite spring perch with a stainless steel insert?

The polyamide composite material prevents oxidation and corrosion between the spring perch and the strut body, ensuring that height adjustments remain easy over time. The stainless steel insert adds strength and durability to the perch itself.

Are these coilovers covered by a warranty?

Yes, these ST XA Coilovers come with a 5-year limited warranty with unlimited mileage, reflecting their construction and testing standards.

Product Details

ST Suspensions is known for providing well-built suspension components, and their ST XA Coilovers are a prime example of that commitment. If you're looking to fine-tune the stance and handling of your 2008-2013 BMW 1 Series E82 Coupe, these coilovers give you the control you need. They allow for extensive adjustment of both ride height and damping, so you can dial in the perfect balance between sporty road control and everyday comfort.

What sets these coilovers apart is the attention to detail in their construction and adjustability. The spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This combination prevents corrosion between the strut and perch, ensuring that height adjustments remain easy over time, while the stainless steel provides solid strength. Each damper is hand-tested on a shock dyno by experts at KW in Germany to confirm it meets factory-recommended forces before it's boxed. You get 16 distinct clicks of rebound damping adjustment, easily controlled with a knob, allowing you to precisely tailor your car's driving dynamics to your preference, whether that's a more comfortable ride or a sportier feel.

The galvanized zinc-coated steel struts offer robust corrosion protection for long-term use, and ST has included an integrated dust protection system. This system, featuring elastomer bump stops, works to keep dirt and water away from the hardened chrome piston rod and valve packs, preventing premature wear. Inside, a multi-layered sealing package, mono block guide system, and low-friction piston band operate within a pressure-resistant housing for smooth, reliable damper performance. This kit comes with a detailed manual to help you understand and reset the damper settings.
