Manufacturer Insight

GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered products.

The company's founder, Justin Grimm, has always had a passion for Subarus. 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 Subaru, Justin decided to turn his passion into a career. He immediately realized the niche market for Subaru aftermarket performance and founded GrimmSpeed, initially performing all of the work out of his own garage. As the demand for his own high quality products grew, he opened a new shop in St. Paul, MN. Enthusiasts quickly took to GrimmSpeed, and it became necessary to expand even further to a larger location. In January 2010 GrimmSpeed moved into a 6500 SQ FT shop in Minneapolis, MN. This move has given GrimmSpeed the opportunity to expand for years to come.

Due to the extreme weather conditions of Minnesota, GrimmSpeed has unique opportunities to test their products to ensure quality performance. This allows the engineers to take advantage of a very wide range of conditions for product testing. This enables GrimmSpeed to continuously perform research and development on all products and make revisions accordingly.
