ATTENTION
HSV vehicles are equipped with a Supplemental Restraint System (SRS). An SRS consists of seat belt pre-
tensioners (fitted to all front seats), and a driver’s-side air bag AND a passenger’s-side air bag and left and right
hand side air bags. Refer to CAUTIONS, Section 12M, in the Holden V2 Series Coupe Service Information before
performing any service operation on or around SRS components, the steering mechanism or wiring. Failure to
follow the CAUTIONS could result in pers onal injury or unnecessary SRS system repairs.

1 Purpose
The purpose of this section is to provide information on the font and rear suspension assemblies fitted to
HSV Coupe Series 2 Models. The information is designed to supplement the information contained in the
Holden V2 Series 2 Coupe Service Information, and details are given where differences occur between the
HSV models and standard Holden models. A series of instruction drawings describe the design changes and
indicate specific part numbers, fitting instructions and relevant notes for vehicle servicing.
NOTE
If specific technical data on a HSV model is not
contained in this supplement, obtain data for that
model from the relevant Holden V2 Series Coupe
Service Information Supplement. References are
made throughout this section to Holden Service
Information, to assist in providing information for
specific service operations.
When hoisting (or jacking) HSV models,
ensure that the lifting head of the hoist lifts
on the chassis before the arm of the hoist
contacts the side-skirt.

2 Front Suspension
2.1 General
The front suspension assembly fitted to all HSV Coupe Series 2 models is based on the Holden ‘MacPherson Strut’
design. All HSV Coupe front suspension struts are gas pressurised. This basic assembly (and the rear assembly) is
then modified by HSV to provide a suspension system more suited to the requirements of the HSV vehicle.
A summary of the suspension system and their standard (s) and optional (o) applications are contained in the following
paragraphs.

2.3 Service Operations
Service front suspension assemblies fitted to HSV models in accordance with the relevant Holden V2 Series 2 Coupe
Service Information. Additional service requirements for specific HSV suspension assemblies are detailed in succeeding
paragraphs. Refer to drawing 03I-020001.
CAUTION
Safety And Cautionary Note For Vehicles
Equipped With ABS.
Whenever any component that forms a part of
the ABS is disturbed, it is vital that the
complete ABS system is checked. Refer to
Section 5A Brakes or Section 5B ABS &
ABS/ETC of the Holden V2 Series 2 Coupe
Service Information.
The tyre life of high performance low-profile tyres fitted to HSV vehicles is very sensitive to the toe-in setting of the front
suspension. It is crucial therefore, that care is taken to set the toe-in accurately to the correct specification.
The front wheel alignment specification for HSV Coupe vehicles is:
Coupe
Toe-in Degrees Total 0°10' ± 0°10'
Degrees Per Wheel 0°05' ± 0°5'
Camber -0°30' ± 0°20'
Caster 7°45' ± 1°15'
NOTE
The wheel alignment needs to be checked with
the vehicle at kerb weight (full fluids, full tank, no
load).

4.2 Service Operations
The differential oil must be changed at 45,000 km intervals. Use synthetic hypoid gear oil to HN2040 such as ‘Mobilube
SHC 80W-140 ID’.

4.3 Limited Slip Differential
PRECAUTIONS
(From Holden Commodore VS series Service Manual)
(Volume Number 2)
CAUTION
When servicing a vehicle fitted with a Limited
Slip Differential, never run the engine with the
transmission in gear and one wheel raised.
The driving force to the wheel on the ground
may cause the vehicle to move.
NOTE:
'On Car' type wheel balancers are not
recommended for use on the rear wheels of cars
equipped with a Limited Slip Differential. One
rear wheel will drive if in contact with the ground
when the opposite wheel is raised. This type of
balancer may be used by removing the wheel
opposite to the one being balanced with the
vehicle raised and supported on safety stands.
(Refit wheel nuts, reversed, to retain brake disc).
