THIS KIT INCLUDES THE FOLLOWING: (click items for details)
Complete Front Strut Housing - Machined from seamless DOM 1026 steel alloy tubing. High clearance sway bar bracket welded on.
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. 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.
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!
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 OEM BMW parts, but made to our specs in Germany. Our race bump stops are even different than our street bump stops.
Ground Control Top Mount Camber/Caster Plates - More camber adjustment than stock. Ground Control designed bushings, 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. The steering bearing is sealed for long life.
Camber and caster are quickly adjustable by sliding the mounts, without removing any components from the car. The priority of this design is to allow repeatable alignment changes for fine tuning.
Ground Control Rear Camber Plates - Bottom mount, more camber adjustment than stock, caster adjustment, aircraft bearings, with stainless steel reinforcement.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.
*Suspension is shipped completely assembled and preadjusted*
