The above link demonstrates the new Endura-Tech Monotube coilovers in action on an 06 STi. I know that the STi is not of interest here in the 240SX crowd, but I think the information and video is pertinent none the less to see the actions that the coilovers on any car are undergoing. It is just a cool little piece of video.
This video was taken at the Joliet, IL Autobahn Race Course on the South Loop. It is a pretty good piece of video (although you probably won't want to watch the whole 7 minutes) showing the compression and rebound of the coilovers, the spring working in conjunction with the damper.
The specs on these coilovers are:8k front / 7k rear spring rates. The video shows the right side rear coilover.15 levels of rebound adjustment. In the testing, the dampening level was set at 2 front and rear from full soft.
225/40/18 Yokohama Tires on 18" OZ racing Ultra Leggra wheels.-2 degree of camber in front, -1.25 in the rear.
The intent of these coilovers is for the enthusiast that is looking for a more track worthy set up with use on a DD (meaning they are willing to make some compromises to the daily driver for a more track oriented set up). In comparison to these are the Endura-Tech twin tube coilovers that are for the more DD user who wants to be able to track their car without compromising their DD comforts.
Enjoy!
