OUR STORY
GrimmSpeed was born in 2006, inside a single-stall garage in Maplewood, MN. What started as a small operation focused on porting and polishing Subaru manifolds quickly evolved into something far greater than we ever imagined. Fueled by a relentless passion for performance and innovation, we grew—fast. Not just in size, but in spirit, vision, and capability.
As our community of enthusiasts expanded, so did our product line. GrimmSpeed began engineering performance solutions for more platforms—Mitsubishi, Ford, Mazda, VW, Hyundai, and others—without ever compromising our commitment to quality. We weren’t just chasing power; we were building perfectly integrated systems that delivered real results and brought people together. In the end, we decided to narrow our focus back to what we knew best, making the best Subaru parts for our customers. Every product is a testament to our knowledge and love of the Subaru brand, and we love bringing you the best options for your vehicle.
In 2019, we took a major step forward by partnering with an organization of aftermarket performance companies who shared our core values. That collaboration unlocked access to new resources, cutting-edge technology, and better infrastructure—including a brand-new warehouse and engineering facility. The result? Faster product releases, increased manufacturing capabilities, and superior customer service. The GrimmSpeed experience leveled up, and so did our ability to serve the performance community.
From the very beginning, GrimmSpeed has been guided by three core principles:
Innovation That Matters
Every great idea starts with a simple question: Can we make this better? We don’t build parts just to build parts. Every new design—whether an original idea or a smarter version of an existing component—must deliver meaningful value. That means better performance, better reliability, and easier installs. If a product doesn’t raise the bar, we won’t make it. Period. That’s our promise, and the reason GrimmSpeed parts consistently exceed expectations.
Precision Engineering, Built In-House
Quality doesn’t happen by accident—it’s built through precision, experience, and an uncompromising attention to detail. That’s why we engineer and manufacture as much as possible in-house, controlling every step of the process to guarantee our products meet the highest standards. We’re not just some faceless brand outsourcing production; we’re enthusiasts who live and breathe the culture, the kind of people who would rather spend an entire weekend dialing in the perfect setup than settle for “good enough.” We design, test, and refine every product as if it’s going on our own cars—because more often than not, it is.
Customer Service You can Trust
We know the struggle. The waiting, the troubleshooting, the excitement of finally bolting on that new part. That’s why we’re committed to supporting our customers every step of the way. If something is delayed, you won’t get a vague excuse—you’ll get the truth. If you run into an issue with an install, our team will walk you through it, because we’ve been there ourselves. No scripts, no runaround, just real support from people who genuinely care. When you choose GrimmSpeed, you’re not just buying a part—you’re joining a community that shares your passion.
From intercoolers and exhausts to boost controllers and phenolic spacers, every GrimmSpeed part reflects the passion that started it all. We’re not just here to sell products—we’re here to make driving better, to push the limits, and to keep that garage-built spirit alive.
Because at the end of the day, we’re just like you.
