Putting spacers in the springs is a really stupid idea. It effectively turns one spring into two or three, depending on how many spacers you install, by interfering with the compression of the springs in a uniform manner from top to bottom. The ride will get incredibly stiff, and you'll get permanent spring damage in a very few miles. If you want a taller ride height, install taller and/or stiffer springs. You'll also be running the suspension geometry out of its normal relationship by the height change, which induces tire wear problems and handling issues. Bad idea!
