performance driving.
.Check the engine, transmission, differential
and under the vehicle for oil and coolant
leaks.
. Inspect the areas surrounding of the cata-
lytic converter for heat deterioration.
. Always perform the transmission setting.
After that, adjust the clutch clearance so
that the clearance is less than the clearance
used for daily driving. Your GT-R certified
NISSAN dealer has the necessary informa-
tion and equipment to set the clutch
clearance to the correct specification. The
clearance used for daily driving increases
clutch heat generated during Performance
Driving. This leads to an increase in tem-
perature of the transmission oil. In addition, a
more direct shifting feel can be obtained by
reducing the clutch clearance for Perfor-
mance Driving. The clutch clearance should
be reset to the daily driving specification
after Performance Driving. It is recom-
mended you see a GT-R certified NISSAN
dealer for information.NOTICE
Failure to have the clutch properly
adjusted before performance driving
may cause the transmission oil tem-
perature to increase which may cause
transmission damage.
. Inspect and confirm the clearance between
the exhaust finisher and rear bumper is more
than 0.24 in (6 mm) (up/down) and more
than 0.20 in (5 mm) (left/right) .
. Inspect the dust boot of the drive shaft
universal joint for cracks or damage.
Suspension and wheel alignmentGUID-54A24DDC-5371-47E4-A29D-23C634F0898DThe information and specifications in this
section apply only when engaging in
performance driving.
.Check the steering and suspension system
and other links for loose and/or damaged
parts.
. Measure and adjust the wheel alignment.
(
ªWheel alignmentº page GTR-9) It is
recommended you contact a GT-R certified
NISSAN dealer to adjust the wheel align-
ment to the recommended setting for high
performance driving. Preventing toe-out:
Toe-out can cause uneven tire wear or
damage to areas inside the tires due to
high heat. Be sure to have the wheel
alignment toe-in setting checked and ad-
justed by your GT-R certified NISSAN
dealer before any performance driving on
closed circuit tracks. Obey all traffic laws
when on public roads.

Suspension and wheel alignmentGUID-717B8FCC-38D9-49B8-900D-CE3AC60083CD.Check the steering and suspension system
and other links for loose and/or damaged

. Measure and adjust the wheel alignment. It
is recommended you contact a GT-R
certified NISSAN dealer to adjust the wheel
alignment to the recommended setting for
normal driving.
Wheels and tiresGUID-DF739C54-232F-4D22-8411-3447FCC6AF9E.Check tire wear and cracking.
. Inspect the tire side wall for damage.
. Check the tire pressure and adjust the
pressure as necessary when the tires are
cold. (

16) If you do not drive under the conditions
listed in this section, see
ªWheels and
tiresº page 8-32.
. Check that the wheel nuts are not stripped.
Check if there is no deformation on the
contact surface of the wheel nuts.
. Make sure the wheel nuts are tight.
(
ªWheels and tiresº page 8-32)
. Make sure the drive shaft nuts are tight.
. Check wheel hub run out and that the wheel
rotates smoothly without any friction. Check these with the tires removed whenever an
inspection is performed with the vehicle
jacked up.
. Make sure the tire has not slipped on the
wheel causing the assembly to be out of
balance. The reference marks on the tire and
wheel should be aligned. If the reference
marks are not aligned, the tire has slipped on
the wheel. Have the wheels/tires reba-
lanced. Make sure the old reference marks
are erased and new reference marks are
applied to the wheel and tire. When instal-
ling new tires on the wheels, make sure new
reference marks are applied to the wheels
and tires. (

. Make sure that the TPMS sensor installation
nuts and the sensor valve are tight and there
is no nitrogen leak.
BrakesGUID-9F9BF18B-725B-4D67-9B77-FE9C5E2B01AC.Check for the heat deterioration of the
brakes and parts around the brakes.
. Check the condition of the brake pads and
disc rotors and replace them as necessary.

. Inspect the area surrounding the catalytic
converter for heat deterioration.
. Inspect and confirm the clearance between
the exhaust finisher and rear bumper is more
than 0.24 in (6 mm) (up/down) and more
than 0.20 in (5 mm) (left/right) .
. The clutch clearance and shift fork position
may need to be adjusted.
. Inspect the dust boot of the drive shaft
universal joint for cracks or damage.
. Check that there is no abnormal noise,
vibrations or warning lights illuminated when
making tight turns at slow speed (for tight
corner braking phenomenon) .
