Challenge Car Frame<\/h3>\n

A great car starts with a great chassis.\u00a0A chassis is the foundation of the house. Today’s fourth-generation Mk4 Roadster frame has benefited from years of refinement and development. It is both lightweight (376 lbs.) and strong.<\/p>\n\t\t\t\n\t\t\t\t\t\t\tLEARN MORE\n\t\t\t<\/a>\n\t\t\t\"\"\t\t\t\n\t\t\t\t

“This ain’t no kit car.”
\n– Mustang & Fords Magazine<\/h3>\n

The Challenge car chassis is built on the strong foundation of our world class Mk4 frame. Connected to that beautiful tube steel frame is an array of aluminum panels bonded and riveted in place like any good race car should be. Aluminum panels make-up the car’s sub-frame and liners.<\/p>\n\t\t\t\n\t\t\t\t\t\t\tLEARN MORE\n\t\t\t<\/a>\n\t\t\t\"\"\t\t\t\n\t\t\t\t

Period-Correct Shape,
\nMade Correct. Period.<\/h3>\n

The Factory Five Challenge model comes with the same hand-laid vinylester composite body as the Mk4. The doors are single panel (unlike the double-lined and hinged doors of the Mk4), and have pre-drilled mounting holes and positioned hood. Lamination thickness is 3\/16″ all around with .015″ coat of gloss red gel coat.<\/p>\n\t\t\t\n\t\t\t\t\t\t\tLEARN MORE\n\t\t\t\t\t<\/a>\n\t\t\t\"\"\t\t\t\n\t\t\t\t

\nSuspension & Brakes<\/h3>\n

The strong Challenge chassis is complemented by an outstanding and proven suspension and the ability to use a wide array of excellent brake packages. Suspension design and engineering is an extremely challenging endeavor. Over the years we’ve found what works best in the real world of racing. You can’t get lucky and you can’t say it works unless you prove it. The only way to prove it is at a track and under the most extreme circumstances over many, many years.<\/p>\n\t\t\t\n\t\t\t\t\t\t\tLEARN MORE\n\t\t\t\t\t<\/a>\n\t\t\t\"\"\t\t\t\n\t\t\t\t

\nRunning Gear<\/h3>\n

In the early days most challenge car were built with spec Mustang running gear (engines\/trans\/rears). Nowadays with the proliferation of not only spec legal series cars, but monster open track customs, we can only tell you what fits (with respect to engines etc)… we can’t tell you what to use!<\/p>\n\t\t\t\n\t\t\t\t\t\t\tLEARN MORE\n\t\t\t\t\t<\/a>\n\t\t\t\"\"\t\t\t\n\t\t\t\t

The interior of the Challenge car is all about the business at hand. No carpeting or street seats here. You get all the functional interior pieces and trim that comes with the roadster, except for items that are not needed by racers.<\/p>\n\t\t\t\n\t\t\t\t\t\t\tLEARN MORE\n\t\t\t\t\t<\/a>\n\t\t\t\"\"\t\t\t\n\t\t\t\t

Challenge Car Exterior<\/h3>\n

While it’s true that most folks will only see you as you blur past them from 50 feet at more than 50 mph, a good number of people will look at your car up close in the pits. Just because this is a dedicated race car doesn’t mean the small trim doesn’t matter.<\/p>\n\t\t\t\n\t\t\t\t\t\t\tLEARN MORE\n\t\t\t\t\t<\/a>\n\t\t\t\"\"\t\t\t\n\t\t\t\t

Our Safety Record
\nIs No Accident<\/h3>\n

The legends of the ’60s were built not only from racing victories, but from tragedies as well. Back then, many basic safety features were either not used or not available. Today’s Factory Fives are stronger, faster, and\u2008safer than the original cars.<\/p>\n\t\t\t\n\t\t\t\t\t\t\tLEARN MORE\n\t\t\t\t\t<\/a>\n\t\t\t\t\n<\/a>\n\t\t\t\t\n<\/a>\n\t
