Recessed Plate Fitment
This is where
a recessed metal plate is welded into position. This procedure is a
preparation step for the actual installation of the Lambo Door
is it needed?
modern cars there is enough space to install a Lambo Door, which
needs around 3-4 inches of clear space to operate to its maximum
potential. Modern cars have this space as part of the side crumple
zone. Older cars do not, and typically have only 1-2 inches, which
seriously reduces the ability of a Lambo Door kit to operate.
cars (mostly older) have weld on hinges and nowhere to bolt the
Lambo Door kit to, and need a recessed plate to provide something
significant to bolt the kit to.

welding needed, and also from the cutting.

You need a
large grinder – cut out a large proportion of the A post, and weld
into place the recessed plate. The Lambo Door can then be bolted
into position as normal. See pictures below.
It is vital
that the strength removed when cutting into the A post is replaced.
That is the reason that the plate we supply tends to be between 6mm
and 10mm thick depending upon application.
be carried out to a high standard. Full penetration welds between
thick and thin metal is a challenge – we would not use a MIG of less
than 300 Amp for this job – pigeon shit welds are worthless for any
job, for this they will be dangerous.
MUST be 100% seam welded into position – stitching, tacking or spot
welds are neither suitable, safe nor legal.
This is at
the highest level of complexity of Lambo Door installation. If you
find yourself unable to carry out this work, then we are only too
happy to do it for you. If you really struggle then please call

much as you need.
||This is a typical A post in need of a
recessed plate to get decent lambos working. Here you can see the
wing, and wiring, plus the door have been removed, to prevent
damage. We use a 9 inch grinder to remove the bulk of the metal, and
4.5 inches grinders to tiny up afterwards.
||The large plate being fitted is used as a
template. This plate must be large enough to fit the lambo door
mechanism to, and positioned to allow adjustment, and correct
operation of the kit.
The technique is to draw around the plate
and then cut slightly inside it with the 9 inch grinder. Then tidy
up with the smaller grinder so the plate "just" fits - as this will
make the welding far easier.
Accuracy is important if both sides of the
car are to be the same.

be under no illusion - this is a significant part of the strength of

|Once you have installed the
plate, it can then be drilled and tapped in the correct position for
your lambo door kit to bolt onto. This procedure is a conversion for
mainly older, and European cars which either do not have enough
space under the wing, or else have welded hinges.
