Each GC Kit includes the following: (4) Eibach  Linear Springs: All of our ride height adjustable kits exclusively feature Ground Control springs, manufactured by Eibach USA. A broad selection of street and race spring rates are available. All Eibach / GC springs offer a lifetime warranty against spring rate change and sagging. Eibach springs are used on all of our VAC cars and we trust them implicitly. (4) Height 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 handsome 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.   (2) Front Camber Plate Strut Mounts: Ground controls brand latest revision Touring Camber / Caster Plates feature waterproof, German-made, axial load steering bearings and feature: . Unique slot design allows for caster correction. . Revolutionary caster adjustment that can be locked or unlocked. . Urethane center mounts reduce NVH, yet do not flex. . All components plated or anodized for corrosion resistance. . Zinc plated mounting bracket for ease of install and adjustment. Adds extra travel to avoid excessive bottoming out, this is a very well engineered product. . Camber and caster are separately adjustable by sliding the mounts, without removing any components from the car. (2) Rear-Upper Shock Mounts: Billet aluminum rear upper mounts eliminate the failure prone stock pieces and allow a more predictable & sporty Koni adjustable shock. Bump stops are provided and assembled on the shock. Urethane upper spring pads are used to insulate the spring for sound and comfort.   (4) Ground Control valved Koni Dampers/ Shocks: The shocks and struts in this GC kit are not the standard off-the-shelf Koni. The front struts are adjustable from the top, and are shortened with special valving designed by Ground Control. The rear shocks have a slightly more aggressive valving compared to off the shelf Konis, but still offer streetable damping like the front struts.   (4)Bump Stops: This kit includes four Ground Control bump stops, designed and manufactured for GC, and matched to your kit for direct compatibility with the Koni dampers. Ground Control Wrench Set: Plates steel for a lifetime of use. Used for height adjustments as desired

 

Notes, Tips, and Questions when ordering:

Low Ride Heights: For Customers who wish to have the most comfort  and performance at low ride heights, we recommend going with option B or C, to allow proper suspension travel if you plan to keep the ride height low.

Rear Suspension- Lower than 2 inches can cause rear alignment problems and excessive suspension geometry changes (Lowering more than 2" is recommended for cosmetics only, and can hurt performance). If you wish to lower more than 2" on a non M-car model, we recommend you install our Rear Camber-Caster adjustment kit for Semi-Traling arm BMWs.
Front Suspension- For very low street cars, or cars that are being built for track use, both of these types of cars have low ride heights and need front struts capable of performing while the car is lower than stock. For this, we recommend options B or C...

Whats Option A, B, C?  This refers to teh front suspension. There are no PARTS price difference in these options, however there is labor involved if you select option C.
Option C means that we send your front spindles to Ground Control. They then convert them to coil-over, shorten, reinforce, and powder-coat your strut housings for $205 a pair and they come back ready to bolt to your car.
