About Underground Dynamics

We are a lifestyle brand that promotes the custom performance car culture through its parts offerings, resources, and services. We founded Underground Dynamics in 2007 and have continued to develop it because of a common love for cars. We believe that expressing yourself through your car---whether its performance, styling, or both---is special. We aim to be the best resource for that expression.
