• Streetable ride height change / adjustment from 0 to -2 inches.

  VAC Tech Notes: that for ride highest Lower than 2 inches can cause rear alignment problems and excessive suspension geometry changes (Lowering more than 2" is recommended for cosmetics only, and can hurt performance). If you wish to lower more than 2" on a non M-car model, we recommend: our Rear Camber-Caster adjustment kit for Semi-Traling arm BMWs

  For Customers who wish to have the most comfort  and performance at low ride heights, we recommend going with option B or C, to allow proper suspension travel if you plan to keep the ride height low when street driving.

Springs: All of our ride height adjustable kits exclusively feature Ground Control springs, manufactured by Eibach USA. A broad selection of street spring rates are available. All Eibach / GC springs offer a lifetime warranty against spring rate change and sagging. Eibach springs are used on all of our VAC cars and we trust them implicitly.

Adjusters: All adjusters consist of a threaded sleeve and adjustable spring seat and are made using high strength 6061-T6 aluminum; anodized for greater durability and appearance. The threads on the adjusters are square cut which locks the adjustable spring seat in place under load. For further precaution, a setscrew in the adjustable spring seat can be used to secure adjustment. Upper spring perches are used to insulate the spring.

Rear-Upper Shock Mounts: Billet aluminum rear upper mounts eliminate the failure prone stock pieces and allow a more predictable & sporty Koni adjustable shock. Bumps stops are provided and assembled. Urethane upper spring pads are used to insulate the spring.
 

Dampers/ Shocks: The shocks and struts in this GC kit are not the standard off-the-shelf Koni. The front struts are adjustable from the top, and are shortened with special valving designed by Ground Control. The rear shocks have a slightly more aggressive valving compared to off the shelf Konis, but still offer streetable damping like the front struts.
 

Bump Stops: This kit includes four Ground Control bumpstops, designed and manufactured for GC, and matched to your springs.
