also to quote YAMPUG.
"adjustable coilovers are not designed to be used to make your car sit lower or higher so you can think it looks pretty. if you lower it your springs are going to be so squashed up they won't work and if you higher it they won't do **** all.
Shadeyman, AndyRKett liked this post"
lowering the car does not even slightly squash the coil......... it lowers the lower attachment to the strut so slides the strut further up into the spring. the compression on the spring doesnt even slightly change
.
and although there not designed to slam the car, it does allow you to lower the car and increase the damping to stiffen it up.
