RATIONALE
The GDT Speedster was designed and built by a team of experienced automotive engineers, stylists and a body-surfacing expert who love cars and who wanted to do a complete vehicle from scratch without the bureaucratic encumbrances of a large corporation. The project was initiated as an exercise in engineering and styling with “no holds barred”. It was also considered to be an engineering challenge because many projects like this one are started and very few are completed. In addition, the project was intended to be completed at a “reasonable” cost when compared to OEM produced one off show cars.
The team selected the vehicle’s name, GDT Speedster. It stands for Gene Dickirson Team Speedster. A speedster is the type of vehicle that typically has no top, no side windows and a raked back windshield intended for fun driving in good weather.
THE VEHICLE
Exterior
The GDT Speedster features a beautiful body designed by stylists Craig Sandvig and Larry Ronzi. The theme is fresh and it is intended to retain its freshness for many years to come. The eye catching windshield angle is only 19 degrees from the horizontal and utilizes a header less steel support structure. The sculptured side panels are dramatic in the way their surfaces “converge” just behind the upper edges of the doors.
The highlight of the rear view of the vehicle is the fully visible, polished stainless steel/ aluminum exhaust system. Just behind the gleaming tail pipes is the aluminum intensive rear suspension with axel half shafts which are fascinating to watch when the vehicle is in motion. The front of the speedster has a polished aluminum grill “floating” within a handsome opening. The hood is hinged at the front and when opened provides full access to the engine compartment. Similarly, the rear deck is hinged at the rear and when opened provides access to a small storage compartment behind the seats. The rear deck contains a polished aluminum fuel filler door with the team logo laser etched into the surface.
The body is painted Torch Red.
Interior
The interior is trimmed in Light Oak leather. The instrument panel is custom styled and fabricated. It is attractive to look at and easy to use. The top of the instrument panel is trimmed in leather. The instrument cluster features custom built gauges with the team logo printed on the faces of the speedometer and the tachometer. A unique PRNDL gauge is used to indicate the transmission gear selected. The PRNDL gauge is located in the central portion of the instrument panel next to the clock. Only four switches are needed on the instrument panel to operate the electrical system. To the left of the steering column is a black rocker switch for ignition ON-OFF with a green LED to indicate ON. To the left of the ignition switch is a red rocker for START. To the right of the column is a black rocker switch for lighting. Next to the light switch is a black rocker for HEATER-OFF-A/C. The three-way heater A/C switch has red and blue LED’s to indicate the mode selected. A foot operated headlamp dimmer switch is used. The brake and accelerator pedals are trimmed with polished stainless steel bezels.
The custom designed gear selector knob has leather covering the tapered portion of the polished aluminum body. The leather covered central console sweeps into the rear deck and the team logo is embroidered into the upper face. The seats are custom built for the GDT Speedster by Cerullo Performance Seating. The steering wheel is custom built by Lecarra and the polished aluminum horn button has the team logo laser etched into the surface.
Frame & Underbody
The GDT Speedster frame is very strong. It is fabricated from rectangular steel tubing with a wall thickness of 3.1 mm (.12 inches). The main side rails are 51 mm wide and 152 mm high (2 inches x 6 inches). The under body and dash panel are fabricated from steel sheet fully welded to the frame rails. All welding was done by aerospace/military certified welders.
Drive Train
The engine, transmission, differential, front and rear suspension, steering and brakes are from a Chevrolet Corvette.
Wheels & Tires
Fikse built the beautiful; three piece forged and polished aluminum wheels especially for the GDT Speedster. The front wheels are 18 inches in diameter and 10.5 inches wide and the rear wheels are 18 inches x 12 inches. The Michelin Pilot Sport tires are size 285/35x18 on the front and 335/30x18 on the rear.
