ST Suspension Height Adjustable Coilover Suspension System With Adjustable Rebound Damping (2008-2013 128i Base, 135i Base, 135is Base) - 18220062
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 feature adjustable rebound damping which puts you in control of how comfortable or sporty your car feels.
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.
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.
