Product Details
Ground Control Coilover Completion Kits for the 1992-1999 BMW 3 Series RWD (E36) bring true ride-height control to your 3 Series, letting you dial in exactly the stance and corner balance you want instead of living with one fixed factory height. Built around a threaded, spin-to-adjust spring perch system, this kit lowers the car and tightens up body roll for a flatter, more planted feel through corners — all while working with the stock or aftermarket struts you already run.
Every kit is hand-built in the USA and backed by a lifetime guarantee on the complete assembly, not just the springs. Ground Control is the West Coast distributor for Eibach's ERS race spring line, so your car rides on premium springs warrantied against sag and rate change for life, paired with anodized 6061-T6 aluminum adjusters that lock securely under load.
