(From GDT Press
Release) The GDT Speedster is an exciting, one-of-a-kind, high
performance sports car designed and fabricated by a team of
automotive professionals. It has been hand crafted and is intended
for sale to a discriminating collector who appreciates beautiful
automotive styling, excellent engineering and fine craftsmanship.
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 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.
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.
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.
