UMI's lowering package consists of four Viking double adjustable shocks, a hybrid front coil over spring system and either 1 or 2 inch UMI rear lowering springs. With moderately increased spring rates for improved handling, this kit allows you to adjust your cars altitude and attitude for maximum performance and a cool appearance. The hybrid front coil system features 0-3" front drop and is easy to adjust and lock in place. The 1 or 2 inch rear lowering allows you to knock the factory height down a bit or go the extra inch for the Pro-Tour look. Double adjustable Viking shocks feature 19 compression and 19 rebound settings. These independently adjustable settings allow you to change from street to strip to corner carving handling simply by turning the knobs. No tools required.
Spanner Wrench & Thrust Bearing Kit: Spanner wrench tool is used to adjust vehicle height while shock stays mounted. This wrench is needed to make height adjustments. The thrust bearing kit is designed to be placed between the spring and the spring seat attached to the shock. This makes for easier adjustments since the spring seat is rotating on a bearing. This kit is recommended for easier adjustments but is not needed to complete the installation. We do not recommend adjusting without a thrust bearing kit.
Baseline shock settings - 6C,8R all around street, 10C,12R all around corner carving, 6C,2R front and 6C,6R rear strip
Double adjustable features 19 independent compression and rebound settings (for a total of 361 possible combinations)
