04-08 Chrysler Crossfire / 96-04 Mercedes SLK R170 Ride Height Adjustable Spring Coilover kit.
This is the full adjustable coil-over kit that can include Koni Race shocks/dampers, 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. The adjustments should be made with weight off the wheel being adjusted. It does away with the stock coil spring and spring rubber.
These can be order either with or without dampers, you can use either your factory dampers or koni adjustable dampers.
The kit has an expected ride height adjustment from 0 to -2.5".
