The Factory Five Mk4 Roadster is the world's best-selling, best-engineered, and best-performing replica of all time.
There is no better way to honor a legacy than to continue it. The Mk4 Roadster is designed to accurately reproduce the looks of the legendary 427 Cobra*, keeping its essence intact, while using modern technology, parts, and materials to improve performance, reliability, and comfort.
"Brawny good looks, high quality materials, outta-my-way exhaust note, abundant thrust. A primal brute that will confirm all your mother-in-law's worst suspicions."

Kit Options
Two Ways to Build Your Mk4
There are two ways to build your Factory Five Mk4 Roadster. You can use parts from a Mustang donor car (Base Kit) or you can get all-new parts from us (Complete Kit). Either way you choose to build your Factory Five Roadster, we have engineered the kit to make the process of building your own car as simple and straightforward as possible.
Mk4 Roadster Base Kit
$14,990
The original Factory Five Mk1 Roadster was based on the innovation of using running gear from a single donor vehicle, namely, the high-performance Ford Mustang. The concept was, and still is, so simple. If you have our base Mk4 kit and running gear parts from a 1987-2004 Mustang GT donor car, you already have all the parts you need to build and drive your car!
Mk4 Roadster Complete Kit
$20,990
Over the years we have expanded our chassis kit to include factory-new parts as well. Our Mk4 complete kit delivers to you… well, a complete kit. The only additional things you’ll need are your own engine/transmission/rear end, wheels/tires, and paint.
