The Ground Control Coilover Kit is a street/sport kit designed to fit the BMW 5 series (E34) model for the years 88-97. It allows for customization of the ride height, with an expected change in height of 0 to 2 inches. Please Note: lowering the vehicle more than 2 inches can result in rear alignment problems.

Ground Control spring kits that have been adapted for street use after being used in racing applications for several years. The unique design of the system allows for easy adjustment by simply lifting the corner(s) of the vehicle that requires adjustment and spinning the adjustable spring seat up or down to raise or lower the vehicle. The kit is designed to be used with either stock or aftermarket shocks.

Ride Feel Options	1- Street Ride 1. (with clients and/or wife)
	2 - Street Ride 2. (with friends and/or dates)
	3 - Sport Ride. (1 track day a year)
	4 - Hot Rod. (surprise a Vette)
	5 - Frequent Track Visits

Springs: All of our ride height adjustable kits now exclusively feature Ground Control springs, manufactured by Eibach USA. A broad selection of street spring rates are available. All Eibach / GC 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.

Rear upper shock mounts: Billet aluminum rear upper mounts eliminate the failure prone stock pieces. On the e34 M5, they also eliminate the nivomat suspension, to allow an adjustable shock. Bumps stops are provided and assembled. Urethane upper spring pads are used to insulate the spring.

Bump Stops: This kit includes four Ground Control bumpstops, designed and manufactured for GC, andmatched to your springs.

Camber Plates: HYBRID Camber / Caster Plates A special version of our camber/caster plates, toned down for dual-purpose cars. Uses a proprietary upper perch with a urethane spring insulator. More camber adjustment than stock, caster adjustment, aircraft bearings, engraved with calibrated degrees. Every component is anodized or plated, including fasteners. 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.

The Ground Control camber plates feature two sets of bearings, a proprietary bearing, made to our specs by Aurora in the USA, which allows for articulation of the shock shaft. This spherical bearing is very understressed, as the GC design does NOT support the weight of the car on the spherical bearing. Instead, the weight of the car is supported by a completely separate articulating needle bearing, which is also manufactured for Ground Control in the USA.

The shocks and struts in this kit are not the standard off-the-shelf Koni struts for the e34. 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, but still streetable damping like the front struts.

Ground Control works with Eibach USA to manufacture these springs to high standards. The kit comes with a lifetime guarantee on everything, not just the springs. If any component fails while being correctly installed, it will be taken care of. Every single part of the Ground Control Street coil-over kit is made by them or someone they trust.
