Custom machining · fabrication · automotive wiring
M20 combines precision CNC machining, custom fabrication, and real-world racing experience to build parts and systems that fit, function, and perform.
Three ways M20 can help
From a billet component to a complete automotive electrical system, every job starts with the same question: what does it need to do?

About M20
M20 Machine and Fabrication is led by Matt Obertanec—owner, operator, programmer, fabricator, and racer. That combination matters. Parts are considered as pieces of a complete system, not isolated objects on a print.
Motorsports is a proving ground, not a limitation. M20 brings 20 years of mold experience, extensive mold-design capabilities, and CNC capacity spanning prototypes, custom one-offs, small runs, and full production work.
