Mace Manufacturing

Welcome to Mace Manufacturing. I’m Stuart Mace, a Mechanical Engineer by trade, with a journey rooted in the exciting world of automotive design and manufacturing.

Attending UNC Charlotte and receiving my Mechanical Engineering degree with a concentration in motorsports was hardly the beginning. Upon graduation, I immediately accepted a position as an aerodynamics design engineer for a NASCAR cup team and began honing my skills in component design and rapid prototyping. These skills complimented my responsibility to develop innovative machining methods when I joined an aerospace company in 2017.

In 2023, I took a leap of faith and founded Mace Manufacturing. My tinkering on nights and weekends began with 3D printers and CNC routers. This eventually evolved into acquiring a CNC plasma table to design and fabricate a replacement floor for my 1974 Toyota Land Cruiser. As most of you know, as we get older, our tools just get bigger and more expensive. In February of 2023, I decided to sell my dream car, which was a 1993 Nissan Skyline GTR, to purchase a HAAS VF2 and challenge myself to develop unique and innovative automotive machined accessories.

Mace Manufacturing intends to start writing our Cinderella story right now. We don’t claim to have a state-of-the-art manufacturing operation. Our humble beginnings begin in my home garage, and we want you to embark on this journey of developing and growing with you, the customer, by our side.

At Mace MFG, our principles are simple but unwavering:


Exceeding Expectations

We don’t aim to mass-produce outsourced products. Everything is made in-house in Fort Mill, South Carolina, undergoing rigorous quality inspection and fit tests.


Customer Care

Focusing on quality over quantity allows us to build meaningful relationships with our customers. We’re available every day to answer your questions because you chose to invest in us.



It’s the heartbeat of our company, setting us apart from other automotive component manufacturers. While our product range may be limited now, we’re committed to expanding our offerings in the years to come.

I invite you to explore the world of Mace Manufacturing and join me on this exciting journey. Let’s connect, share ideas, and together, explore the endless possibilities that the world of innovation holds.

Thank you for being a part of this adventure!
