Concept III was established by CEO William Chang. His passion and lifelong dream of one day owning an empire in the automotive industry began at a young age. When William was a teenager, he would spend most of his time not only modifying cars, but also learning to repair all types of cars. His talent and skill for modifying and repairing cars stems from his diligence and dedication acquired through the times and from his work experience with top companies in the industry. With this cultivated knowledge, William had an idea to reconstruct automotive parts in order bring out the full potential of the car in every aspect.

Concept III was an idea, turned reality, bred from a passion for speed, performance, and automotive customization. Over the years, KDM (Korean Domestic Market) was laying low under the radar until a line of performance vehicles were released from manufacturers such as Hyundai and Kia. William capitalized on the opportunity to capture the clientele of this newly emerging market by offering fine tuned performance parts along with customized aesthetic parts to make his clients cars stand out from the sea of newfound KDM machines. 

Concept III is striving to be the one-stop shop that caters to all vehicles for aftermarket and OEM parts. We stock nothing but the best top quality products while providing excellent customer service to all of our clients. We provide our services to our customers with the utmost respect and integrity. Allow us to provide you with the services you need in order to gain the best performance from your vehicle. With our dedication to customer service and performance enhancements, we will “Revolutionize the way you drive!”
