Grimmspeed founder, Justin Grimm, has always had a passion for cars. Just like most enthusiasts, he was satisfied with his vehicle's performance stock, but could not resist the urge to see just how much more potential was left untapped. After a few years of perfecting his ideas and techniques on his own personal vehicle, Justin decided to turn his passion into a career. He immediately realized the niche market for aftermarket performance and founded GrimmSpeed, initially performing all of the work out of his own garage. Enthusiasts quickly took to GrimmSpeed, and it became necessary to expand.
