About Us

Bad Ass Cars is owned by Arron Johnson, a long time racer and hot rodder that grew-up in the east bay area of northern California. Remember when you were in school and there was that kid with the baddest car in town?... that was Arron. Never took auto shop, never played by the rules, and never took any prisoners when it came to building cars and engines. Arron was truly the "John Milner" from American Graffiti in his area.

Since then, Arron has built countless cars and engines that have won all kinds of shows, been in numerous magazines, have set track records at several tracks, and have been class champions in numerous race circuits, from drag racing, to road racing, to mud bogs, to Baja off road racing, to drag boats, to Bonneville & beyond!

I deal on a personal level with each of my clients and provide the highest quality & best service possible. My reputation and track record of thousands of happy clients around the world speaks for itself."
