Billetworkz - Dedicated to the Enthusiast

Driven by Passion. Built for Performance.

Founded in 2014 by Austin Barnett, Billetworkz was born from a deep love for custom builds and the car community. With a Mechanical Engineering degree from Penn State, Austin brings a sharp eye for performance, precision, and personalization. His passion for cars started young—fueled by time spent with his father—and has only grown since. His iconic “Rexzilla” RB26 build is a true reflection of the craftsmanship and dedication behind everything we create at Billetworkz.

From One-Off Builds to a Full Line of Custom Parts

Billetworkz began in 2014 with a single focus: designing custom shift knobs that elevated both form and function. As the car community embraced our work, our product line quickly expanded—from a few knob styles to a full lineup of interior accessories, engine bay dress-up kits, and exterior components. In 2020, we moved into a larger facility to support increased demand and bring more of our machining and anodizing processes in-house. Today, Billetworkz continues to grow with new product categories, vehicle fitments, and finishes—serving both weekend wrenchers and show car veterans with the same passion and precision that started it all.

Looking Ahead

At Billetworkz, we’re just getting started. As the automotive world evolves, so does our vision. We’re exploring new manufacturing techniques, expanding our lineup with even more customizable components, and tapping into emerging vehicle platforms. Our goal is to continue pushing the limits of both performance and personalization—giving enthusiasts more ways to make their build truly their own. No matter how the industry changes, our commitment remains the same: delivering precision-crafted products that blend innovation, style, and function.
