Coilover Conversion Kit, BMW E30 Chassis Ground Control works very hard with Eibach USA to make these springs to the standards that you demand. Lifetime guarantee on everything, no t just springs. No excuses about "racing" or "special". If anything fails, while being correctly installed, it will be taken care of, period. We can only have a guarantee like this because every single part of the Ground Control Street coil-over kit is made by us or someone we trust. None of these parts are made in Taiwan. Everything is made in the USA. Spring Kit - This spring kit gives you the option to customize the ride height of your vehicle. After several years of use in racing applications, Ground Control spring kits have been adapted for street use. Most other spring kits offer only one set ride height when installed. The Ground Control system's unique design allows for easy adjustment. Simply lift the corner(s) of the vehicle that you wish to adjust and spin the adjustable spring seat up or down to raise or lower the vehicle*. Ground Control spring kits are also designed to be used with either stock or aftermarket shocks. Adjusters - All adjusters consist of a threaded sleeve and adjustable spring seat. And are made using high strength 6061-T6 aluminum; anodized for greater durability and appearance. The threads on the adjusters are square cut which locks the adjustable spring seat in place under load. For further precaution, a setscrew in the adjustable spring seat can be used to secure adjustment. Upper spring perches are used to insulate the spring. NOTES: Fits all popular replacement inserts... Koni, Bilstein, Tokico, KYB, etc. (please specify shock type when ordering) Removal of stock spring seat and welding optional for added tire clearance and range of adjustment. *Some applications require the use of a provided wrench.
