Ground Control single adjustable coilover kit
for the BMW E30 is a hugely popular setup for the enthusiast. We
have the best price!
Everything you need in a package deal that can't be beat...
Dollar for dollar the best setup around!
Provided is everything you need to make a great performance street
vehicle or track setup from your E30...
Most people find that the stock, or even the popular H&R +
Bilstein setup is just far from what they expect from one of BMWs
most celebrated 3 series: lack of suspension stroke and height
adjustability means uneven ride quality, lacking performance, and
awkward looks.
Certainly not what you were looking for, and far from ideal on
either your street car or track vehicle.
The Ground Control kit is a winner... We recommend selecting the
"Short Front" housing option above for those who want to lower
their E30 more than 1.2" and get the best looks, ride quality, and
importantly -function at a low ride height. We also recommend
adding our bolt-on VAC Roll Center Spacers for best results by
correcting suspension geometry if you have an E30 M3.
*Image is an example of a fully assembled kit. Product will
require assembly. Shown with Ground Control Welded and
Powder-Coated Service available as an option. Your strut housings
must be sent in for this service.*

- GC front Camber Plates with aurora bearings; either Standard
style or Hybrid [hybrid uses polyurethane cushion, a bit quieter on
the street]

adjusters

Each Kit Includes the best components. See the GC
difference:
(4) Ground Control custom valved
Koni single-adjustable dampers ([2] front strut inserts, [2] rear
shocks)
Koni Single Adjustable Front Strut Custom Valved strut inserts are
externally adjustable from underneath the hood, even with the
factory strut brace. This strut is prepared for coil over use, and
eliminates machining of critical suspension components.
Koni single adjustable rear shocks
Ground Control / Koni Single Adjustable Rear Shocks Preadjusted by
Ground Control to match your rear spring rates using our shock
dyno. The GC custom valved version of this kit is the "top-adjust"
version, which adjusts from inside the trunk or under the hood with
no tools needed.
Ground Control Hight adjustment
Ground Control Threaded Sleeves
This system is designed to eliminate
stress risers caused by machining notches into the strut housing.
Unlike other companies that claim superiority by cutting threads
into a critical component of the suspension, Ground Control uses
engineering common sense to maximize the strength of the
suspension.
Ground Control Adjustable Spring Perch A unique design, that uses
an allen head bolt to clamp the single threaded perch into the
correct position. No secondary pieces are needed to "jam" the
threaded perch into position. This method of clamping onto the
threads also prevents sand, grit, and water from getting into the
threads, which is a common problem with jam nuts.
Pair (2) front Camber
Plates
Ground Control Racing Camber / Caster Plates More camber adjustment
than stock, caster adjustment, aircraft bearings, engraved with
calibrated degrees, with stainless steel reinforcement. Every
component is anodized or plated, including fasteners. Adds extra
travel to avoid excessive bottoming out, this is a very well
engineered product. The stainless steel reinforcement prevents
electrolysis between the steel fender and the aluminum camber
plate.
Camber and caster are separately adjustable by sliding the mounts,
without removing any components from the car. The priority of this
design is to allow fast, repeatable alignment changes at the
track.
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 Ground Control 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.
4 Eibach ERS springs, (not pro-kit), with a race OR street
spring rate.
Eibach Springs Any spring rate is available. Eibach springs are
made on German machines both in the USA and in Germany, however all
Eibach springs have a lifetime guarantee against sagging, rate
change, or any manufacturing or material failure. Lifetime
guarantee. Compare.
(4) Ground Control bump stops (made in Germany)
Ground Control Bump Stop We do not just ask you to reuse your stock
bump. The stock bump stop is designed for stock suspension we
provide a bump stop designed to work with our suspension. These are
soft foam, same quality as OE BMW parts, but made to our specs in
Germany.
2 Rear ride height adjusters
Ground Control Rear Ride Height Adjustment Kit Billet aluminum
threaded adjusters press onto the top of the rear control arm.
(2) Rear Upper Shock Mounts, heavy duty (urethane) for great
feel and control with comfort. Reduced fatigue to chassis shock
mounting points.
Bushings can be installed in either a stiff or semi-stiff position,
this is the perfect rear shock mount . 6061 aluminum, with two
steel studs mounted to a steel bracket sandwich this mount to the
body, and allow quick access from under the wheelwell for adjusting
rear shocks, especially Konis. lifetime guarantee.
For those who want the ultimate Ground Control
setup, GC can shorten housings, reinforce mounting points,
install perches and powder coat your struts casings for $190 per
pair (select this option above, requires your housings to be mailed
in)
professional install is highly recommended.
