Steering and Wheels
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 airbags. Refer to CAUTIONS, Section 12M, of the Holden Series V2 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 personal injury or unnecessary SRS system repairs.

1 Purpose
The purpose of this section is to provide information on the wheels, tyres and steering wheels fitted to the HSV GTO and
GTS Coupe Series 2 models. The information is designed to supplement that given in the Holden V2 Coupe Series 2
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 Coupe Series
Information. References are made throughout
this section to Holden Service Information, to
assist in providing information for specific service
operations.
CAUTION
When hoisting (or jacking) HSV models,
ensure that the lifting head of the hoist lifts on
the chassis before the arm of the hoist
contact the side skirt.
1.2 Service Operations
All service operations for the steering and wheels fitted to the HSV GTO and GTS Coupe Series 2 Service Models. Refer
to the HSV VT Clubsport Service Information and Drawings: 09I-030001, 10I-010001, 10I-020001 and 10I-010002.

2 Steering Wheel
ATTENTION
HSV GTO and GTS Coupe Series 2 vehicles are equipped with AIR BAGS. An AIR BAG is a Supplemental
Restraint System (SRS). Refer to CAUTIONS, Section 12M, of the Holden V2 Coupe Series 2 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 air bag deployment, resulting in possible personal
injury or unnecessary SRS system repairs.
The steering wheel assembly fitted to all HSV Coupe Series 2 models incorporates a HSV-design central horn pad
complete with HSV logo (Refer to Drawing 09I-030001). The central horn pad also incorporates the driver’s-side air bag.
All other components, fixtures and fasteners are identical to standard Holden parts and therefore, any service operations
on the assembly should be carried out in accordance with the relevant Holden Service Information Supplement, refer to
Section 9A Steering of the Holden V2 Coupe Series 2 Service Information.

3 Wheels And Tyres
3.1 General Description
HSV GTO and GTS Coupe Series 2 models are fitted with alloy wheels developed specifically for each HSV
application. Several types and sizes of wheel are manufactured to suit the various applications and each
wheel is manufactured from a single-piece alloy casting.
NOTE
Specific wheel nuts are used to attach ‘T’ Design
wheels to the vehicle. These nuts are fitted with a
plastic dress cap, which must be removed prior to
undoing the wheel nuts.
CAUTION
HSV GTO and GTS Coupe Series 2 wheels do
not have a steel insert and therefore require
wheel nuts with a flanged seat as per the VT,
VT2 and VX wheel nuts, 10B-970304. DO NOT
use VS wheel nuts on HSV Coupe wheels.

3.2 Service Operations
Alloy wheels fitted to all HSV vehicles are to be serviced in accordance with the procedures detailed in the relevant
Holden Service Information, refer to Section 10 Wheels And Tyres. In addition, particular care should be taken with the
surface finish of alloy wheels. The manufacturer recommends that alloy surfaces be treated the same as high-gloss
painted surfaces to prevent corrosion and general deterioration.

3.3 Wheel and Tyre Balancing
In order to balance the HSV Design wheels and tyre assemblies, refer to the relevant Holden Series Service Information,
refer to Section 10 Wheels And Tyres of the VT Series II Service Information.
NOTE
HSV wheels are balanced with concealed
weights. The lateral distance between these
weights is considerably less than the actual width
of the wheel. To achieve wheel balance within
specification with concealed balance weights, set
the balancing machine for a wheel width of 5.5”.
Figure 10I-010001, 10I-010002 and 10I-020001
also explains this requirement.
