i must agree with mrbrace about the spring rate. these things will be stiff as hell. dropzones (unfortunately i knew someone who had them) are typically pretty stiff and if you look at the springs, they are very small, similar to that of a sleeve coilover which are usually on the stiffer side. save a few more bucks and spend the money on some quality parts. don't get something just b/c the price is appealing, unless you have done the research and discovered that they are quality parts. like said many times before........you get what you pay for.
