Mk4 Anatomy, Part 1: A Closer Look at the Summit Racing/Factory Five Mk4 Roadster

OK, we’ve had several people ask for the specs on the Summit Racing/Factory Five MK4 roadster project. You ask, and we deliver—sort of.

In today’s post, we’ll show you what the guys at SKJ Customs received from Factory Five as part of the kit. We’ll give you the rundown of what Summit Racing used to complete the project in an upcoming post.

Remember, Summit Racing will offer the parts and accessories it supplied in pre-packaged kits so you can duplicate the build yourself…if that’s your thing.

So without further ado (sorry for the delay)—here’s what Factory Five supplied:

The Factory Five Racing MK4 frame is a complete jig-welded original style four-inch round tube frame, which includes all mounts ready to accept small block Ford and 1987-2004 Mustang running gear. It comes powdercoated in gloss black, includes a three-point roll bar, and also includes mounts to accept a passenger-side roll bar.

Body
The hand-laid 3/16-inch laminate composite body and panels are made with vinylester resin. The body comes with driver and passenger doors, hood and centered hood scoop, trunk, trim, fasteners, and weatherstripping. You also get hinge kits for the doors, hood, and trunk.
