Standard kit includes:
Complete front strut housing, machined from seamless DOM 1026 steel alloy tubing. Heavy duty swaybar bracket welded on. This strut is designed to be easier to install than the stock strut, because the lower control arm does not need to be removed when using our strut housing. You will need to remove the lower control arm or separate the ball joint to remove the stock strut however.
Koni double adjustable strut . Externally adjustable rebound on top, externally adjustable compression underneath the strut.
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.

we don't cut threads in our strut housings.
Ground Control adjustable spring perch. A unique design, that uses a 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.
Eibach spring. Several choices of rates are available. Street, track, or school. 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 Camber / Caster Plates. More camber adjustment than stock, caster adjustment, urethane bushings, engraved with calibrated degrees, with a 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.
Ground Control Bump Stop. 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.
