Drop: 0 to 2". For 9th Generation Honda Civic Si.
Ground Control Adjustable Coilover Kits allows you the option to customize the ride height of your vehicle. Unlike other spring kits that require removal of the strut assembly, the unique design of the Ground Control kit allows for quick, easy adjustment. Simply lift the corner(s) to be adjusted and spin the adjuster up or down to raise or lower the vehicle. Ground Control spring kits are designed to be used with either stock or aftermarket shocks.
All height adjustable kits feature Eibach Springs. These high quality springs offer a lifetime warranty against defects. All adjusters consist of a threaded sleeve and adjustable spring seat and are made using 6061 aluminum, anodized for greater durability and appearance. All other adapter hardware is machined from the same high strength 6061 T-6 aluminum.
