Ground Control E36 3 Series Koni/Eibach Track/School Coil-Over Kit

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, 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.

2 SHORT Koni single adjustable rear shocks

Koni Single Adjustable Rear Shocks Preadjusted to match rear spring rates using our shock dyno. Your choice of two adjustable versions. The standard version, which needs tools and a jack to adjust, and the "top-adjust" version, which adjusts from inside the trunk with no tools needed. The "top-adjust option adds $100 to the kit price.

2 Urethane/aluminum rear shock mounts

Machined Aluminum Rear Mounts from Ground control have a durable urethane bushing and include shock tower reinforcement plates.

Eibach Spring Any Ground Control spring rate is available, (this is not exactly the same as the full race kit, for which any GC or Eibach spring 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.

Ground Control Bump Stop We do not just ask you to reuse your stock bump stops. 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 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.

Simple, easy to install, excellent road feel
