THIS KIT INCLUDES THE FOLLOWING: (click items for details)
Koni Single Adjustable Front Strut
- Struts 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. The sway bar
bracket is reinforced beyond the stock or regular Koni bracket.
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
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.
Koni Single Adjustable Rear Shocks - Preadjusted to match rear spring rates using our shock dyno. The street/track is now exclusively the "top-adjust"
version, which adjusts from inside the trunk with no tools needed. The
rear shocks are custom built and valved by Koni to GC specifications,
and are shorter than standard Konis.
- All popular street spring rates are available. Ground Control springs
are made by Eibach 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
Ground Control Bump Stop
- We do not just ask you to reuse your stock bump stops. 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 OEM
BMW parts, but made to our specs in Germany.
Ground Control Rear Ride Height Adjustment Kit
- Billet aluminum threaded adjusters bolt on top of the rear control
arm. The e36 M3 has a larger diameter rear axle than the standard E46,
so it is necessary for clearance to not have any portion of the adjuster
below the control arm.
Ground Control (Street) Camber/Caster Plates
- More camber adjustment than stock, caster adjustment, aircraft
bearing, 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
Camber is quickly
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. Caster is adjustable, when necessary to
correct tha car, by changing a shim under the plate.
Ground Control camber plates feature a urethane bushing that carries
the side loads only, and does not rotate (no squeek!) and allows for
articulation of the shock shaft. This urethane bushing is very under
stressed, as the Ground Control design does NOT support the weight of
the car on the urethane bushing. Instead, the weight of the car is
supported by a completely separate rotating ball bearing, which is also
manufactured in Germany. The entire assembly is machined at an angle,
just like the stock upper mount. Beware of less expensive machining that
bends the strut shaft after installation.
Ground Control Rear Shock Mount - Billet aluminum, urethane bushings, pre assembled. Includes gaskets and reinforcements.
All Ground Control products carry a lifetime guarantee against defects when
installed and maintained correctly. We strongly recommend that all of our products be installed by a competent, qualified mechanic.
