THIS KIT INCLUDES THE FOLLOWING: (click items for details)
Complete Shortened Front Strut Housing - Machined from seamless DOM 1026 steel alloy tubing. Heavy-duty swaybar 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. 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, which 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.
Koni Single Adjustable Rear Shocks - Made in Holland and custom valved to GC specs. Shorter than standard length, with reduced droop length. Preadjusted to match rear spring rates using our shock dyno. Adjusts from inside the trunk with no tools needed. (standard Koni must be removed to adjust)
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 Rear Ride Height Adjustment Kit - Billet aluminum threaded adjusters bolt on top of the rear control arm.
Ground Control STREET Camber/Caster Plates - More camber adjustment than stock, mild caster adjustment, 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. This is designed to be used with the factory strut reinforcements. Camber is 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. Caster is adjustable, when necessary to correct the car, by sliding the plate. The Ground Control camberplates 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 andreinforcements.
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.
