jdm
Stands for Japanese Domestic Market. It is for car parts. Main compaines are Honda, and Nissan. The reason for JDM is because many import cars such as Civics and Integras have been "detuned" to meet regulations in the United States. Therefore swaping a Japanese engine into an "American" Honda Civic is considered intergration to its truest form.

Many difference that many people don't know is it is seperate from the ricer street racing scene. Many races are on profession tracks. Which many enthusist race in Time Attack. JDM compared to ricers are much cleaner in their styling.
