About us
What started as a group of BMW enthusiasts tired of overpriced parts and limited options is now a brand trusted by thousands of owners nationwide.
We designed our own product lines from the ground up and built the production infrastructure to make them happen. No middlemen, no compromises. Just the parts we actually wanted on our own builds.
Now we operate out of Oceanside, California, engineering valved exhaust systems, carbon fiber, forged wheels, front-mount intakes, and more. Everything is designed in-house, tested on real platforms, and stocked locally for fast shipping.
This is just the beginning.
