hardened washer supplied should be fitted to the
plain side.
These bolts must be tightened by a torque
wrench immediately after the geometry has been
set to the required figures. This is a very critical
area on the suspension, and as a precaution the
torque figure should be checked as a service
operation during vehicle use.

FRONT SUSPENSION DATA
As a direct result of National and International
rallying experience with this model, the GM
Eurosport development engineers in conjunction
with their `team' drivers have optimised the
suspension settings for different types of event
and surfaces. It is suggested that these are
adhered to particularly for the first competitive
outing, after which some drivers may prefer to
make their own subtle changes to these settings
to give slightly different handling characteristics.
The package has been developed for optimum
performance without a front anti-roll bar.
When setting the castor and camber angles, it
is
vitally important that both sides of the car
measure similarly. The tracking figures should
also be regularly checked, sudden discrepancies
i n the measured data could indicate that some
component has been damaged. In Group A
specification this is a very responsive vehicle and
to
maintain driver friendliness attention to the
geometry settings is a priority.

platform is set at 140mm. This is when
measured from the top edge of the spring
platform to the knuckle attachment lugs.
GENERAL COMMENTS
When setting the suspension in the first instance,
it is suggested that the top mountings he
positioned such as to give maximum positive
castor. That is with the top of the strut as far as
possible towards the rear of the suspension turret
aperture. Further adjustment can then be carried
out at the knuckle and the spherically jointed end
of the lower arm as required.
