What is JDM?
It stands for Japanese Domestic Market. What that means is, parts that were built in Japan and intended to be used in cars sold in japan. The parts are different than the parts available in other countries outside of Japan. Sometimes they're significantly better in quality, performance,or appearance. And sometimes they're just simply different. They are difficult to find, and they are expensive. JDM parts consist of either OE(original equipment) or aftermarket parts made by Japanese companies such as Mugen, Spoon, C-West, Buddy Club, Veilside Etc.
