THIS KIT INCLUDES THE FOLLOWING: (click items for details)
Complete Front Strut Housing - Machined from seamless DOM 1026 steel alloy tubing. Heavy-duty swaybar bracket welded on. This strut DOES NOT need wheel spacers, it is a clean sheet design, not a modified stock housing.
Double Adjustable Strut - Externally adjustable rebound and compression on top, US patent 5,988,330.
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 and 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.
Double Adjustable Rear Shock - 2024 alloy construction means this shock weighs 2.2 lbs, less than 1/2 the weight of a Bilstein adjustable. This shock is also shorter than stock, Bilstein, or standard Koni to prevent constant bottoming of the suspension.
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!
Ground Control Bump Stops - 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. Our race bump stops are even different than our street bump stops.
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 e36, so it is necessary (for clearance) to not have any portion of the adjuster below the control arm.
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.
Ground Control Rear Shock Mount - Billet aluminum, spherical bearings, preassembled. Includes gaskets and reinforcements.
This kit can be made as a rear coil over for NO additional charge.
* Suspension is shipped completely assembled and preadjusted*
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.
