BMW E30 Complete Coilover Suspension,
THIS KIT INCLUDES THE FOLLOWING: (click items for details)
Koni Single Adjustable Front Strut - Strut inserts are externally adjustable from underneath the hood. 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.
Ground Control / Koni Single Adjustable Rear Shocks - Preadjusted by Ground Control to match your rear spring rates using our shock dyno. The GC version of this kit is the "top-adjust" version, which adjusts from inside the trunk or under the hood with no tools needed.
Eibach Springs - 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!
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.
Ground Control Rear Ride Height Adjustment Kit - Billet aluminum threaded adjusters pressonto the top of the rear control arm.
Ground Control Rear Shock Mount - Billet aluminum, urethane bushings, pre-assembled. Includes gaskets and reinforcements.
