The two-piece forged aluminum transverse control arm of the front axle allows for
continuous camber adjustment.
Camber adjustment can be done in two different places: The rough initial adjustment
is achieved with different spacers in the transverse control arm. For fine adjustment
of the camber, slots in the front axle dome allow displacement of the strut mount.
The following adjustment washers can be purchased at Porsche Motorsport:
0.30 mm
0.60 mm
0,80 mm
1.00 mm
The maximum permitted spacer width that can be achieved by combining individual
spacers (2) is 18 mm on the front axle. The transverse control arm must be installed
in such a way that the screw connection of the camber adjustment washer is
accessible from below. The longitudinal control arm has to be screwed to the inner
hole of the strut bearing. The mounting screw of the transverse control arm and
longitudinal control arm has to be inserted from above (1).

When inserting the spacers it´s important to use as
less spacers as possible to get to the desired length.
This prevents potential clamping force loss caused by
settling process.
Thinner shims have to be mounted on the inside of the
wishbone (side of the fixed bearing). This will avoid a
clamping of the shims on the tapered area of the stud
(see red colour, picture 3.2.2.3). The picture shows a
section of the left wishbone assembly.
