Who We ARE

Aaron Stauber Owner and Lead Fabricator
ASE Certified Master Technician

    The driving force behind Big 3, Aaron is skilled and experienced in nearly every aspect of automotive performance and restoration. After years of working in high-end shops, Aaron decided it was time venture out on his own and was presented with the opportunity to buy Big 3 Performance in 2011 and take the business in a new direction. Aaron strives to provide results that customers will brag about and give them the proper service that they pay for.
    While Aaron is a muscle car guy at heart, he is equally comfortable restoring a 32 Ford, tuning a turbo import, rebuilding a Ferrari V12, building a custom set of twin turbo headers or setting up a nitrous system on a big block chevy.
