Justin Grimm developed a passion for Subaru vehicles in 2002. He enjoyed taking them apart and improving their performance. After a few years of enjoying his passion for Subarus, he decided to make a career out of it. After realizing the niche market for aftermarket performance products, he founded GrimmSpeed out of his garage. He then later opened up his shop in St. Paul, MN where today the company produces innovative products for other nationwide Subaru enthusiasts.
