towers. Note that the two studs adjacent to the slot in
the lower stud plate fit in the center of the existing hole
in the strut tower. Drill a hole for the third stud.
Weld the doublers to the top of the strut tower with
the stud plate in place to assure proper alignment. Note
that the stud plate assembles from underneath the strut
tower.
Install the moveable camber plate per Carrera in-
structions.
Rear Anti-Roll Bar
The XI 19 doesn't come with anti-roll bars on either front
or rear. In order to minimize chassis roll in cornering,
which couples into a reduction in negative camber, it is
desireable to increase suspension roll stiffness substan-
tially from stock. Thic is partially accomplished by using
stiffer suspension coil springs. Anti-roll bars are

show the suggested rear anti-roll
bar configuration. The size can be altered to suit the driver
and individual car. Increasing the diameter of the rear
anti-roll bar will increase the oversteer. A 518 inch diam-
eter rear bar works well with the other modifications
described here.
Fabricate the rear anti-roll bar mounting brackets per
Drawing 3 and weld them to the chassis as shown in the
pictures.
Fabricate the threaded blocks and weld them to the
rear control arms as shown in Drawing

The rear anti-
roll bar can be purchased as PBS Kit Number 6.
Rear Suspension Bushings
Alinabal CBC-8-B2, or equivalent, 112 inch spherical bear-
ings can be adapted to replace the rubber bushings in the
rear suspension arms. PBS Kit Number 11 contains the
required parts for this conversion.
Remove the stock rubber bushings and their steel
jackets by pressing them out of the inboard ends of the
two rear suspension arms.
Since 14mm spherical bearings are not readily avail-
able, the
112 inch Alinabal CBC-8-B2 units are recom-
mended. These have an outside diameter of
1.3

inches.
This diameter must be ground to 1.260 inches so they
can be pressed into the suspension arms.
Press the spherical bearings into the center of the
openings in the suspension arms. Fabricate locating
