Front
Anti-Roll Bar Pickup Brackets and Front Arms and Trailing Links
Fabricate the front anti-roll bar per Figures
2,4,
10
and 11. Only weld the arm on one end of the bar as the
bar must be inserted through the body before the op-
posite end is welded in place.
Fabricate the front anti-roll bar mounting brackets
(Drawing 10) and bearing blocks (Drawing
4)
and install
them in the front trunk.
Fabricate the anti-roll bar pick-up brackets, which
mount on the transverse suspension control arms, per
Drawing 11.
Install the anti-roll bar and weld the arm on the bar
in the car. Align the two arms so they lie in the same lat-
eral plane before welding.
Front Suspension Bushings
It is recommended that the rubber bushings at the in-
board end of the front transverse control arms and the
front end of the front trailing links be replaced by spher-
ical joints and rod ends respectively. Note that since a
line extending the axis of the bolt through the inner
transverse pick-up doesn't intersect the pivot point of
the trailing link, a straight bushing cannot be used with-
out causing binding. Therefore, any non-flexible suspen-
sion bushing must have freedom in two axes. Eliminating
the rubber joints and replacing them with spherical joints
greatly improves steering accuracy under racing corner-
ing loads.
Bore the inner ends of the transverse control arms to
accept 7/16 inch spherical joints. Alinabal
PIN CBC-7-B2
joints or equivalent are recommended. Bore in, leaving a
shoulder to seat the ball joint against, such that it will be
centered in the arm. A piece of thin-wall tubing can be
pushed in after the ball joint and tack welded in place to
retain the ball joint. PBS Kit Number
8
has these parts.
Cut and thread the ends of the trailing links as shown
in Drawing 12 to accept
518
inch female rod ends. Alinabal
PF-10-G rod ends or equivalent are recommended. Also
fabricate spacers per Drawing 13. This modification is

BRAKES
The X1/9 has four-wheel disc brakes
well in stock form. However, there
which work quite
are a number of
changes which can be made to improve their performance
under racing conditions. The 1500 F-production car is
allowed to use Lancia 10 inch disc brakes as an alternate.
These are recommended for the front. Front
X1/9 calipers
can be used on the rear of both
G
and
F
cars to eliminate
the hand brake mechanism. Some method of adjusting
the relative brake pressure between the front and the rear
