After Opel had presented in 1982 a study of
a Corsa Spider on the Motor Show in Geneva, an agreement was obtained
with the Irmscher GmbH, in order to manufacture a series production of a
Spider in the workshops of Irmscher in Remshalden. The sales start
was in March 1984.
The Spider could be ordered thus in all
equipments at the Opel dealer and was available with all standard
engines (45PS - 72PS) as well as with the Irmscher 1.3l injection engine
(83PS). The Opel warranty remained.
The 3-door Corsas were delivered immediately
from the factory in Spain to Irmscher, where they were converted to
Spiders. The delivery was done without tail gate and without inside
panels in the trunk.
The roof was cut off at the windscreen frame
and on the B and C-columns. Subsequently, reinforcements were welded to
the sills, at the rear side panels, at the window frame and at the floor
(in the interior). Furthermore the metal back of the one-piece backseat
was welded in the back of the car, a little further backwards, so that
between this and the rear seat a box for the roof bars was created.
Finally the top of the side panels were covered with particularly made
sheet metals. The door frames were cut off at the top of the A-column
and at the bottom of the B-column and sealed with a rubber plug. The
door seals were also shortened.
The trunk lid and the roof compartment cover
were made of fibreglass (btw. at the trunk lid, the lock striker was used
from the Corsa Saloon and the hinges of the Manta B). The roof
compartment cover was bolted to particularly made sliding rails, so that
it could slide over the trunk lid when opened.
A foam coated rollover
bar, which could be folded in the compartment behind the backseat, was
fastened on the B-pillars. For the further stabilization of the roof, a
second bar was fastened to the B-pillars, which stands with closed roof
at approximately 45° between the rollover bar and the compartment. In
addition a brace between the rollover bar and windscreens frame is
fastened on each side.
single-layer roof was not conceived as
a folding roof, it is only buttoned (therefore named as Spider and not
Cabriolet), i.e. after setting up the rollover bars and fastening the two
braces to the windscreen frame, it was fixed to the compartment cover with pushbuttons and to the
rollover bar with Velcro fasteners. Furthermore it is fixed on a bracket
along the windscreen frame and spanned with 2
levers on the 2 braces.
are the exact operating instructions of the roof:
The Spider could be ordered with all possible
Irmscher extras, such as front and rear bumper, side skirts, twin
headlight grill, leather interior (very rare!!)
from 1987 on, a fibreglass Hardtop
with or without heated back window (was used from the Corsa Hatch) was available. The side windows
were made of polycarbonate. To the installation, the compartment cover
had to be removed.
