This Ground Control Spring Kit is the perfect option to customize the ride height of your BMW 2002 model with stock, Sachs, Boge, Tokico Premium Performance, Tokico Illumina, Koni, or Bilstein shocks (please specify shock type before ordering). However, removal of stock spring seat and welding is required, and an expected ride height change from 0 to 2 inches can be expected.
Ground Control's Spring Kits have been adapted for street use after several years of successful use in racing applications. Unlike most other spring kits that only offer one set ride height when installed, the Ground Control system's unique design allows for easy adjustment. Lift the corner(s) of the vehicle that needs to be adjusted and spin the adjustable spring seat up or down to raise or lower the vehicle.* The kit can be used with either stock or aftermarket shocks, depending on the preference of the customer.
The Eibach Race Spring line of springs is exclusively featured in all of Ground Control's ride height adjustable kits. With a lifetime warranty against spring rate change and sagging, all racing and street/show spring rates are available. The adjusters consist of a threaded sleeve and adjustable spring seat made of high strength 6061-T6 aluminum, anodized for greater durability and appearance. The square-cut threads on the adjusters lock the adjustable spring seat in place under load, with a setscrew in the adjustable spring seat to secure adjustment for further precaution. Upper spring perches are used to insulate the spring.
Ground Control takes pride in their partnership with Eibach USA, ensuring that their springs are made to the highest standards. All parts of the Ground Control Street coil-over kit are made in the USA, and a lifetime guarantee is offered on everything, not just springs. If anything fails while being correctly installed, it will be taken care of, period. This guarantee is only possible because of GC's commitment to using trusted manufacturers for every single part of the kit, without relying on parts made in Taiwan.
