How do I adjust the ride height and damping?

Ride height is adjusted using the composite spring perches on the coilovers, which feature a unique trapezoidal thread pitch for smooth adjustment. The rebound damping can be adjusted with a simple turn of the knob on each damper, offering 16 distinct clicks to refine your car's handling.

What is the warranty on these coilovers?

Product Details

This ST XTA Coilover Kit includes a set of four height-adjustable coilovers, linear race springs, aluminum unibal top mounts with adjustable camber plates, and a detailed damper setup manual. These components work together to let you precisely tune your Lexus IS250, IS350, or IS300h's suspension for a more performance-oriented feel.

The adjustable spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This design helps prevent corrosion between the strut and perch, ensuring that you can adjust the ride height smoothly over time. The galvanized steel struts offer good corrosion protection, and each includes an integrated dust protection system to keep dirt and water away from the piston rod and seals. You get 16 distinct clicks of adjustable rebound damping, allowing you to fine-tune the driving dynamics to your preference, whether you're aiming for a more comfortable ride or sharper performance. The aluminum unibal top mounts allow for front axle camber adjustment, which is useful for dialing in aggressive wheel and tire fitment or maximizing tire contact patch for better grip in corners.

ST Suspensions is known for its well-built suspension components, and these coilovers are built by hand by experts at KW in Germany. Each damper is tested on a shock dyno before shipping to ensure it meets factory-recommended settings. This kit is designed to fit your 2014-2020 Lexus IS250, IS350, or IS300h, whether it came with electronic suspension or not. A 5-year limited warranty with unlimited mileage is included.
