A very common complaint from Diablo drivers is that the seat is too
narrow. This is particularly so for the recent 6.0L models. In these
cars the seat and seat back are separate allowing one to be adjusted
independently of the other. This is a long overdue requirement.
for many of us these seats are
actually more uncomfortable than those of the earlier one piece molded
early models because the actual sitting area within the seat is too
narrow. One needs to widen the horizontal area for your butt! This can
be done but it does require a stomach to distort the seat structure.
First the seat must be removed from the car. Unlike seats in
most recent current cars there are no electrical connections to the seat
in Diablos. The seat is simply attached to the car via four bolts to the
floor of the car. These bolts require a rather large Allen wrench.
The seat then lifts up and comes out easily from the car. Be sure to
cover the door sills with tape before pulling the seat out. It is
quite heavy and can easily scratch the car.

Now comes the hard part! We are going to strip off the leather
and cushion padding and bend the metal of the seat frame. This is
not for everyone, but it can be done in a manner such that it can later
be bent back if you later wish to sell the car.
Having pulled the seat from the car, the first ting to do is remove
the side shield at the base of the seat. It's just a piece of carbon
fiber material covered with a layer of leather. It's function is just to
hide the frame sliding mechanism of the seat. It is held in place with
two small screws. One then needs to carefully peal back the
leather side padding of the seat. This is shown in figure 2. Extreme
care must be taken not to rip or stretch the leather. It actually comes
up much easier than you would think. Under the leather is a layer of
white foam padding. This too needs to be peeled back. You should
then have exposed the metal side arm of the seat. These thick steel arms
are welded to a tubular base frame as shown in figure 3. To widen
the seat you must cut these welds with a small circular saw and rather
forcefully bend the side frame out with a crow bar. It sounds and
looks worse than it is! Do this on both sides. You will find
however that you can bend the door side frame out further than the
inside one. This is because there is little room between the seat and
the central gear box housing cover inside the car. Sit in
the seat until you feel you have forced enough width.
Next you must reassemble everything. Use rubber cement to
re-attach the foam padding (figure 5). Then likewise stretch the leather
covering over this foam Figure 6. Figure 7 shows a modified seat
before the side shield is re-attached. Figure 8 shows the seat back in
the car. Note the extra foam I have inserted under the center of
the seat. This is a personal preference (I like a softer seat). I will
be later covered a black leather cover to improve appearances.
