BMW E9X M3 Coil Over Conversion Kit. This kit is available for E90 M3 sedan and E92 M3 coupe variants and is fully compatible with both the base stock suspension (non-electronic) as well as the the M Adaptive electronic damping system (EDC). Not only is it compatible with EDC, it was designed with the EDC shocks in mind! The end result is a true coil-over suspension, with all the adjustability and performance, while retaining the EDC system if your M3 came with it. This is a GREAT option if you want to retain the factory damper adjustment, but control your ride height and handling characteristics.
At checkout please note the last 7 of your VIN and the desired spring rates (if choosing your own). You may also note your intended vehicle use, and we'll help select the best starting point.

This adjustable 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.
- Springs: 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.
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. Ground Control can only have a guarantee like this because every single part of the Ground Control Street coil-over kit is made by Ground Control or someone they trust. None of these parts are made in Taiwan. Everything is made in the USA.
Kit includes everything you need to convert all four corners using your existing dampers.
