-2 SHORT single adjustable, custom valved Konis in Ground Control short strut housings, seamless DOM steel, powdercoated for corrosion resistance.
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 sway bar brackets which are much stronger than stock or oem.
Koni Single Adjustable Front Strut - Struts are externally adjustable from underneath the hood, even with the factory framne 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.
-2 X ADJUSTABLE Koni single adjustable rear shocks
Koni Single Adjustable Rear Shocks - Custom made for Ground Control by Koni in Holland, Preadjusted to match rear spring rates using our shock dyno.
-FRONT Street Camber Plates.
Ground Control Street Camber Plates - More camber adjustment than stock, 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 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.
- 4 EIBACH ERS springs, many rates available, with expert consultation at the time of purchase if desired (or you can choose your own)
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!
-4 GROUND CONTROL bump stops (made in Germany)
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.
-2 REAR RIDE Height Adjusters
Ground Control Rear Ride Height Adjustment Kit - Billet aluminum threaded adjusters press into the body, and are isolated by Buna-N rubber, a GC exclusive to reduce NVH compared to metal on metal adjusters.
-REAR UPPER shock mounts (urethane)
Ground Control Rear Shock Mount - Ground Control exclusive, featuring urethane bushings instead of reusing the stock foam, pre-assembled. Includes plated steel washers and reinforcements.
