GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered aftermarket products. On a more personal level, we are a group car enthusiasts who are working our passions in the lovely city of Minneapolis, Minnesota. Our bread and butter started out anything Subaru. However, after growing our team and engineering expertise, we started developing products for Mitsubishi, Ford, MazdaSpeed, and Hyundai markets. We are a true garage start-up (single stall townhouse garage in Maplewood, Minnesota) and we've been lucky enough over the years to be able to turn it into exactly the business we had dreamed....actually, much more. We have a wide breadth of product offerings including; intercoolers, exhausts, intakes, gaskets, engine pulleys, phenolic spacers, boost controllers, and many more.
