GROUND CONTROL COILOVER KIT E46 M3, STREET / SCHOOL LEVEL (with complete front assemblies)

Ref: 2031.75

THESE KITS ARE CUSTOM BUILT TO ORDER, PLEASE LET US KNOW THE EXACT MODEL AND USAGE OF YOUR VEHICLE, INCLUDING ANY TRACK USE ETC.

THIS KIT INCLUDES THE FOLLOWING:

-2 KONI single adjustable struts
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 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.

-2 SHORT Koni single adjustable rear shocks
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.

-4 EIBACH ERS springs, driver school or track event rate
Eibach Springs - 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 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 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.

-2 REAR Ride Height Adjusters
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.

-1 PAIR front Street Camber Plates
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 plate.
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.

The 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.

-1 PAIR rear upper shock mounts
Ground Control Rear Shock Mount - Billet aluminum, urethane bushings, pre assembled. Includes gaskets and reinforcements.

Estimated Volumetric Shipping Weight : 24.00 Kg

THESE KITS ARE CUSTOM BUILT TO ORDER, PLEASE LET US KNOW THE EXACT MODEL AND USAGE OF YOUR VEHICLE, INCLUDING ANY TRACK USE ETC.

THIS KIT INCLUDES THE FOLLOWING:

-2 SHORT single adjustable, custom valved Konis in Ground Control short strut housings

Complete Shortened Front Strut Housing - Machined from seamless DOM 1026 steel alloy tubing. Heavy-duty sway bar bracket welded on. Our design is much stronger and more rigid than any of the aftermarket housings that are actually modified stock housings, with skip-welded gussets and and all original brake line and abs tabs retained.

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.

Ground Control Threaded Sleeves - This system is designed to eliminate stress risers caused by machining notches into the strut housing.

-2 SHORT Koni single adjustable rear shocks

Koni Single Adjustable Rear Shocks - Preadjusted to match rear spring rates using our shock dyno. Your choice of two adjustable versions. The standard version, which needs tools and a jack to adjust, and the "top-adjust" version, which adjusts from inside the trunk with no tools needed. The "top-adjust" option adds $100 to the kit price.

-1 PAIR 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 under stressed, 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, any racing 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!
