Road Wheels and Tyres (04.04)
Suspension (04.00)
May 2007 Workshop Manual 4-4-7
Repairs
In view of the high performance capability of the vehicle,
damaged tyres should be renewed and not repaired.
Care of Alloy Road Wheels
Aluminium alloy road wheels are covered with a protective
coating. To prevent corrosion it is essential that this coating
is not damaged. When removing or installing tyres only
equipment utilizing spigot or stud hole clamping must be
used. The equipment must not have any moving parts which
contact the road wheel, and ty re levers must not be used.
To clean road wheels use warm soapy water; stubborn stains
can be removed using a soft brush or by using a proprietary
alloy road wheel cleaner.
Road Wheel Alignment
It is important that correct road wheel alignment be
maintained. Misalignment causes tyre tread to be scrubbed
off laterally because the natural direction of the road wheel
differs from that of the vehicle.
A sharp ‘fin’ protrusion on the edge of each pattern rib is a
sure sign of misalignment.
• ‘Fins’ on the inside edges of the pattern ribs, particularly on the nearside tyre, indicate Toe-in.
• ‘Fins’ on the outside edges, particularly on the offside tyre, indicate Toe-out.
With minor misalignment, the ev idence is less noticeable
and sharp pattern edges may be caused by road camber
even when the road wheel alignment is correct. In such
c a s e s i t i s b e t t e r t o m a k e s u r e b y c h e c k i n g w i t h a n a l i g n m e n t
gauge. Road camber affects the direction of the vehicle by
imposing a side thrus t and , if le ft to follow its natural cou rs e,
the vehicle will drift towards its nearside. This is instinctively
corrected by steering towards the road centre and, as a
result, the vehicle runs crab wise. The diagram shows why
nearside tyres are very sensitive to too much Toe-in and
offside tyres to Toe-out. It also shows why sharp ‘fins’ appear on one tyre but not on
the other, and why the direction of misalignment can be
determined by noting the position of the ‘fins’. Severe
misalignment produces clea
r evidence on both tyres.
Front road wheels on a moving vehicle should be parallel.
Tyre wear can be affected noticeably by quite small
variations from this condition. It will be noted from the
diagram that even with parallel road wheels, the vehicle is
still out of line with its dire ction of movement, but there is
less tendency for the wear to be concentrated on one tyre.
The near front tyre sometimes persists in wearing faster and
more unevenly than the other tyres, even when the
mechanical condition of the vehicle and tyre maintenance
are satisfactory. The more severe the average road camber,
the more marked this tendency will be.
Caution
When a new tyre is installe d, always renew the tyre
valve.

Exhaust (09.00)
Silencer Assembly (09.01)
Variable Flow Silencer Assembly
The rear silencer assembly has a variable fl ow path controlled by two bypass valves.
The system is intended to enhance top end performance in mo tor sport applications and will not operate in most normal
driving conditions.
By directing exhaust gasses through a modified path at high vehicle speeds, exhaust back pressure is reduced and top end
performance is enhanced.
As engine speed increase from idle, the bypass valve is open until the engine speed is 1500 rpm.
From 1500 rpm to 3000 rpm, the valve is closed
Above 3000 rpm the bypass valves state is load dependent (fully open at higher loads).

Fuel Tank and Lines (10.01)
Fuel (10.00)10-1-4 Workshop Manual May 2007
Jet Pumps
Fuel feed from the fuel pumps is split three ways:
1. Feed to the fuel rails.
2. Feed to the swirl pot jet pump (integral to the FDM).
3. Feed to the externally mounted jet pump (LHS). These pumps ensure that the appropriate pump swirl
pot is maintained with fuel under severe dynamic
conditions.
Filler Neck and Check Valve
Incoming fuel passes through a check valve at the base of the
filler neck. This valve is normally held closed by light spring
pressure. The valve opens under the pressure of incoming
fuel and closes again when fuel flow ceases. The check valve
prevents surging of fuel in the filler neck.
The filler neck also forms part of the on-board refuelling
vapour recovery system. Incoming fuel forms a liquid seal in
the filler neck. Thus any air displaced during fuel tank filling
cannot escape via the filler neck.
