The basis of the Roaring Forties GT40 is a triangulated space frame with all mounting and fixings factory welded on precision jigs. With the chassis, the intention is that it can be used as the basis of an inexpensive but high-performance road car, while at the same time capable of more serious use, even competition. In this form the chassis would have an integrated roll-over bar, four or five point seat harness mounts and full rose-jointed suspension. All chassis are individually tested and certified to comply with all appropriate Australian Design Rules (ADR’s), which are stringent enough to cater for most registration requirements in many other countries.
The suspension is very similar to the original Ford GT40, with double wishbone front suspension which comprises of independent, non parallel, unequal length “A” frame control arms. The rear suspension has lower reversed “A” control arms, single top link and double radius arms and uses our own cast aluminium or magnesium uprights. All suspension “pickup” points have been positioned via computer design, CAD modelling, CNC machining and extensive road and track testing by professional racing drivers, to ensure optimum performance. The springing is provided by coil-over adjustable dampers front and rear, which are custom built for our car.
The power plant has been extended to include 3 Ford based engine platforms, 302 Windsor, 5.4 Quad-cam and the latest Coyote and Miami derivatives all of which are fully ADR and registration compliant in all Australian States and Territories. The engine is mated to a Getrag 6 speed transaxle via specially designed and manufactured adaptor plates and flywheels.
With the standard configuration, top speeds of 250 km/h and 0-100 km/h times of 5 seconds are normal, but with modified & tuned engines, these figures can be dramatically improved upon.
The body finish is smooth, strong and ripple free. It is constructed from hand laid GRP, manufactured by professional laminators. The roof centre section and the doors are both double skinned and reinforced to ensure a good fit. “Eyebrows” are also available to further enhance sealing of the door/roof area at high vehicle speeds. The recesses for all catches and fuel fillers are ready molded. All edges are fully returned to aid panel fit lines.
Inside the car, again the painstaking attention to detail is obvious. The VDO “Ford GT40 replica” 300 km/h speedometer (specially made for Roaring Forties) together with 8000 rpm rev counter, sit amongst replica fuel gauges, oil pressure gauge, water temperature gauge, battery voltage gauge and clock, together with original “Lucas style” toggle switches. We offer a high degree of original authenticity combined with modern reliability and accuracy.
The holed seats, to replicate the original units, are manufactured specially for Roaring Forties. These items are fully tested to comply with ADR’s, and come standard in black leather with lumbar support, but are available in various styles, including coloured leather and embossing. Original style steering wheel & boss are available to complete the picture.
The footwells have been extended to accommodate a fully adjustable floor mounted pedal box, to assist in accommodating taller drivers. A25mm “drop floor” and door top blister, originally known as a “Gurney Bubble” (after the great racing driver Dan Gurney who won Le Mans in 1967 in a GT40), is also available to accommodate taller drivers.
On the outside of the chassis, all the bright-work is supplied in laser cut aluminium. Even the rivet holes are laser cut for accuracy and hence aesthetic appeal, as well as to ease the build process. Door handles and fuel filler caps are exact replicas of the original, and are cast and machined in Australia for Roaring Forties. Purpose made, AS tested & approved wheels are available from us in a choice of sizes and offsets. The wheels are replicas of those fitted to the original cars (BRM) and are available as knock-on variations, to give that extra attention to detail.
All wiring harnesses are specifically formed, fully terminated, tested plug and play systems. They cannot be installed incorrectly as each connector will only fit to its specified ‘mate’.
