This is a glossary of terms commonly used on our forum and the DSM forums. It contains terms that have to do with our cars, parts for our cars, and the DSM's we borrow them from. Since there tends to be alot of talk about JDM parts, these terms will be included also. Feel free to post some of your own so I can add them, just don't get offended when it gets deleted after I use it.
