rldzhao, if the stock spring preload compression is indeed 2" (JAJ's numbers suggest that is more like 0.8"), then that creates even more room for using shorter and stiffer aftermarket springs, and would explain how H&Rs are stiffer and result in 1" drop. I haven't taken any measurements on any of this, so I'm going with what you guys have posted here so far. All I can measure is the natural length of the stock springs as they are in my basement. I believe the fronts are ~11.5".
