Hey guys,

Bought a lightly used Ground Control suspension kit from another member, the rears sit too high, the rear springs are loose, and Ground Control claims that we're "missing 50 parts and it would be better to just buy a new kit from them."

Any help would be appreciated.

Thank you

What are the spec's on the spring?

Height, rate, diameter?

Did you roll the car a few feet forward and back after setting back down on the ground to get things to settle? There is not 50 parts in a complete kit.

The only thing it looks like you are missing is that alignment cone. Unless that part is already in the car. I assume you got new rear shock mount or its already installed ?
