Built to be the best.


Our founder Rob Primmer knows a thing or two about getting things right the first time. A former engineer on the Boeing Delta IV rocket, he brings attention to detail together with manufacturing know-how, mad design skills, and a life-long passion for anything with wheels (well, maybe not anything). Rob established his business in Costa Mesa, CA to do three things: make cool stuff, build kick-ass projects, and save his clients money.

Mission Accomplished. 

Quality. Personal Service. Precision.

"We keep moving forward, opening new doors, and doing new things, because we're curious and curiosity keeps leading us down new paths."

- Walt Disney
