Who We Are
JM Performance is a dedicated auto repair and performance shop based in San Jose, California. Founded in 2025, the shop was built from years of hands-on experience that began in 2019, starting with the Audi 3.0T supercharged platform.
What started as a passion for high-performance vehicles turned into a mission to provide honest, reliable, and professional automotive services for everyday drivers and performance enthusiasts alike.

Our Story
Our Mission
Our Story
The foundation of JM Performance comes from real-world experience, not shortcuts. In 2019, I began learning and working deeply with a B8 S4, quickly expanding into diagnostics, mechanical repairs, and custom and off-the-shelf performance upgrades. Along the way, we have had modified other cars, such as the N54 and EA839.
Over time, that experience grew into the creation of JM Performance — a shop designed to give customers a trusted place where their vehicles are treated with care, precision, and respect.
Our Mission
We aim to provide dependable workmanship for all vehicles, but mainly focused on German vehicles like Audi, BMW, and Volkswagen. No shortcuts like other places and no high-pressure sales. We just want to keep your car running or help you create your dream build, whether it is a track focused car or a well-balanced street car.
