Australian Engineering. Global Performance.
Founded in Australia in 2019, ZAC Motorsport was built on a simple mission: create beautifully engineered performance products that deliver a superior driving experience.
What began in Greg Geldard’s home garage has grown into a globally recognized brand trusted by enthusiasts who demand exceptional design, premium materials, and proven performance.
Today, ZAC Motorsport proudly combines Australian engineering expertise with U.S.-based operations to better serve customers around the world.
Our Story
ZAC Motorsport was founded by Greg Geldard, an experienced designer and engineer with more than two decades of product development expertise.
Greg launched his own design consulting business in 2005, working across industries ranging from agriculture and mining to aerospace. His practical, hands-on approach and passion for automotive performance led him to design and manufacture the very first ZAC carbon fiber air intakes himself.
Greg’s engineering philosophy remains the foundation of every product we offer: innovative design, uncompromising quality, and real-world performance.
A New Chapter
In 2026, ZAC Motorsport entered an exciting new phase when the company was acquired by Steve DeFrancesco, owner of Junkyard Holdings, LLC.
Steve is an automotive enthusiast and entrepreneur with extensive experience building and operating e-commerce businesses serving restoration and performance customers.
Under Steve’s ownership, ZAC Motorsport continues to build on Greg’s vision while expanding operational capabilities in the United States.
