Over the couple years that I've been on the boards I've repeatedly run into some common misconceptions regarding coil spacers, tbar cranking, and preloading. For instance, a lot of people incorrectly think that adding spacers or cranking tbars add preload.

To dispell these myths I've put together an article that discusses basic suspension component functions and how simple modifications effect the system. Keep in mind that this is a basic look at suspension systems and there are many more things going on than I have explained. Also, this article focuses on coilover suspension but the theory transfers over to any coil sprung suspension and to torsion bars.

I welcome any comments, questions or suggestions you may have. Enjoy.
