GC E34 RACE COILOVER KIT

$2,438.00

If you want to get the most out of your E34, a good suspension setup is key. Ground Control has developed a very functional modular E34 coilover system that can take you wherever you need to go. This coil-over kit gives you the option to customize the ride quality and ride height of your E34 and will handle the way it should on a spirited drive to and from brunch, or on a hard drive on a weekend track day. GC offers a lifetime guarantee on everything. No excuses. If anything fails, while being correctly installed, it will be taken care of, period. 

All components are American made:
  • Ground Control Race Camber/Caster adjustable, Bearing clad front mounts
  • Ground Control Heavy Duty urethane rear coilover mount
  • Eibach Race springs
  • Race proven rebound damping adjustable twin tube struts up front/Custom valved Special Purpose Koni Race rear dampers; rebound damping adjustable, made specifically for GC. Adjustments to rebound damping you can feel, not just clicks of a knob.
  • Fully rebuildable (except koni dampers) with each individual part in stock at GC
  • No gimmicks, just solid, proven suspension. 
Springs: The front and rear spring rates on the race kit are 650F/500R. All GC ride height adjustable kits now exclusively feature proprietary 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. Ground Control works very hard with Eibach USA to make these springs to the standards that you demand.

Shocks: 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.

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 bump stops, designed and manufactured for GC, and matched 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 under stressed, 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.
