For infinite adjustability you need Ground Controls Rear Spring Kit. You can go shopping for individual components but these will come in at the same price or better.  One and done.


This spring kit gives you the option to customize the ride height of your 914. After several years of use in racing applications, Ground Control spring kits are a much welcome adaption for street use. Most other spring kits offer a few off the shelf settings or 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.

*Some applications require the use of a provided wrench.

Springs: We are pleased to announce that Eibach has chosen Ground Control as the west coast distributor for their ERS (Eibach Race Spring) line of springs. All of our ride height adjustable kits now exclusively feature Eibach springs. All racing and street/show spring rates are available. All Eibach springs offer a lifetime warranty against spring rate change and sagging.

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.

Helper Spring Option: Tired of your springs flopping around when you lift the car?  Get some help with a helper spring option.  This is a zero value spring that keeps the top of your spring in the top hat groove when you lift the car. (totally worth it in our book).

Ground Control works very hard with Eibach USA to make these springs to the standards that you demand. Lifetime guarantee on everything, not 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.
