MK4 Roadster - Concept

Vintage Looks, Modern Technology Underneath

The marriage of modern CAD based engineering and vintage design is a winning combination. The world’s best selling AC replica began with a simple but revolutionary concept. Improve performance, reliability and safety, while reducing cost by using the latest CAD/CAM technology, state-of-the-art suspension parts, and using modern running gear.

Build Your Mk4 Roadster TWO Ways

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).

Base Kit – $12,990
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 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!

Complete Kit – $19,990
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 things you’ll need are your own engine/transmission/rear end assembly, wheels/tires, and paint.

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.
