Tein 14+ Lexus IS250 (GSE30L)/IS350 (GSE31L) Street Advance Z Coilovers

For all those who want to influence more than just their ride height. ST XA Coilovers deliver the look you need through a wide range of height adjustment. With an extensively adjustable damper setup, you can precisely adjust the driving behavior of your car to achieve enhanced road control without a compromise in comfort. ST XA Coilover kits deliver precise adjustment to your ride height and look of your car. We manufacture the adjustable spring perch made of durable and friction-optimized polyamide composite material with a stainless steel insert. Thanks to the composite material corrosion is prevented between the strut and perch ensuring long lasting height adjustability while the stainless steel insert provides strength and confidence! ST XA Coilovers come preset to our factory recommended damper settings, the same configuration we test them at on our KW shock dynos before they go into your box. The 16 distinct clicks of adjustable rebound damping allow you to refine the driving dynamics with a simple turn of the adjustment knob. Each kit includes a detailed damper setup manual making it easy to reset to our recommended setting at any time. Whether your preference is comfort, sportiness, or something in between; ST XA puts the finer details of the driving dynamics in your hands. Galvanized zinc coated steel struts optimize corrosion protection for long lasting use. We add a dust protection system to prevent unwanted dirt and particulate from coming in contact with the hardened chrome piston rod or getting into the valve packs. We reinforce the system with a multi-layered pressure resistant sealing package, mono block guide system and a low friction piston band which works inside the pressure resistant internal damper housing.
ST XA Coilovers deliver the look you need through a wide range of height & damping adjustment. Precisely adjust the driving behavior of your car to achieve enhanced road control without compromising comfort.
ST Coilover Kits enable you to individually adjust the ride height of your car to improve the appearance and driving behavior. Depending on your selection, ST coilover kits offer a wide range of adjustments giving you the tools needed to dial them into your requirements.

• Elastomer Bump stop with integrated dust protection system prevents water and dirt particles reaching the piston rod and seals. The highly resilient bump stops act as dynamic load limiters while maintaining ride quality and durability.
• Composite spring perch made from wear-resistant, friction-optimized polyamide composite with an embedded stainless-steel insert. The polyamide composite prevents oxidation while the stainless-steel insert maximizes strength.
• ST coilovers are built by hand by the experts at KW in Fichtenberg, Germany. Each damper is tested on a shock dyno to verify it’s making the proper forces before being put into the ST box.
• Seamless Ride Height Adjustment – ST’s composite spring perch and unique trapezoidal thread pitch make ride height adjustability a breeze so you can dial in your preferred look
• ST XA coilovers feature adjustable rebound damping which puts you in control of how comfortable or sporty your car feels.
• Zinc galvanized steel housing for improved resistance to corrosion.
• 5 Year Limited Warranty – Unlimited Mileage
• Made in Germany

Cutting-edge motorsports technology for more performance on the road. Like every suspension product developed by KW automotive, the suspension manufacturer, and manufactured in Germany, the KW V3 Coilover suspension kit also provides a significant plus in safety reserves in road traffic. Thanks to the chassis with its high-quality dampers, springs, and elastomer spring elements, pitching and rolling movements during load changes such as evasive maneuvers, cornering, acceleration, and braking are significantly reduced. The braking distances are also shortened. Thanks to improved support and feedback, drivers not only feel safer but driving in everyday life becomes even safer. With compression and rebound stage damping, that can be set separately and independently of each other, the damper setup can be customized to your personal driving preferences or vehicle changes such as weight, tire characteristics, or altered vehicle rigidity. True performance optimization is only possible with this unique, patented system. For example, this allows the compression damping force to be increased and get more grip from the tires, to improve cornering behavior and reduce squat without simultaneously altering the rebound stage damping which is optim ally matched to the spring rate, a scenario which results in reduced grip and the associated loss of performance. The KW V3 coilover kit is the ideal tool for performance-oriented drivers and experienced tuning enthusiasts who place a strong emphasis on the overall performance of their suspension. The Variant 3 features patented TVR-A and TVC-A technology that provides separately adjustable rebound and compression damping. The extensive adjustment range of the independently configurable rebound and compression make it easy to directly influence the steering behavior, directional stability, grip and handling characteristics for confident and repeatable results at the limit of driving dynamics.
Unparalleled street performance bred from motorsports heritage, the patented KW-valve technology -or the separate Adjustment -f rebound and compression damping, allows you to individually adapt the vehicle-specific base setup.
For over 20 years, KW automotive has been the market leader and driving innovation as a manufacturer of individual suspension solutions for the road and in all types of motorsports. No matter where in the world, gearheads, automobile manufacturers and reputable tuners rely on our KW coilovers “Made in Germany”. Every KW coilover kit undergoes extensive stress testing before production and is developed and manufactured exclusively in our company headquarters in Fichtenberg, a small in town in Germany, to meet the high standards of our KW quality management. For us as a German manufacturer, it goes without saying that our KW coilover kits will exceed the original equipment manufacturer quality and offer useful and innovative solutions. With an application list comprising more than 4,600 options KW guarantees an outstanding selection backed by our Limited Lifetime Warranty.

• TVR-A (Twin Valve Rebound – Adjustable) technology – allows oil to flow passed an adjustable, conical low-speed bypass during slow damper speeds, while at higher speed, the main rebound stage valve opens for maximum fluid displacement.
• Elastomer Bump stop with integrated dust protection system prevents water and dirt particles reaching the piston rod and seals. The highly resilient bump stops act as dynamic load limiters while maintaining ride quality and durability.
• TVC-A (Twin Valve Compression – Adjustable) technology – patented compression valve allows fine tuning of low speed. During sudden high piston speeds, the low speed needle and main valve blow-off feature open to maximize flow.
• Composite spring perch made from wear-resistant, friction-optimized polyamide composite encompassing a stainless-steel insert. The polyamide composite prevents oxidation while the stainless-steel insert maximizes strength.
• Inox-Line Stainless Steel – Truly Permanent Corrosion Resistance. Inox-Line coatings will not wear off while adjusting the suspension making KW coilover struts 100 percent corrosion resistant with an unlimited lifespan.
• Road legal motorsports technology featuring independent rebound and compression adjustability and application specific spring and damper tuning resulting in unparalleled street performance.
• KW suspensions V3 coilovers are hand built by our expert team and given a uniquely individual serial number at our headquarters in Fichtenberg, Germany.
• Each damper is dyno tested to ensure accuracy and preset to our recommended shock settings before being released for delivery.
