A "spreewell" is a generic term for any rim that has a part that keeps spinning when the tires stop. However, TRUE "spreewells" come a the shop that Latrell Spreewell owns, and they run about $10,000. The "spreewells" that come from a kit are not real "spreewells."
Any regular "Joe" on the street does not have genuine "Spreewells"; they simply have a "spinner kit." So in all honesty I can't begin to give you an example, because NOBODY out here has them.
