The basic kit includes the coil springs and mounting system. The front is height adjustable with a 17mm bolt that you access through the hole in the A-arm. The rear adjuster is at the top but can be adjusted rather easily with a wrench provided. The adjustments should be made with weight off the wheel being adjusted. It does away with the stock coil spring and spring rubber.
The dampers are the shocks. My understanding is they have different springs for stock shocks, basic Koni yellows or KYB's, then the Koni Sport and Race shocks.

In other words, it's completely customizable. You can get a luxury ride kit, a sport upgrade, or kidney busting full race crazy.
