GTR-16GT-R Overview
distilled water mix is used.
Engine and powertrain
The information and specifications in this
section apply only when engaging in
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. See your 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 alignment
The 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.
(
“Wheel alignment” page GTR-10)
Contact a GT-R certified NISSAN dealer to
adjust the wheel alignment to the recom-
mended setting for high performance driv-
ing. 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.
Toe-in specification
Front 0.059 in (1.5 mm)
Rear
0.079 in (2.0 mm)
Suspension and wheel alignment
.Check the steering and suspension system
and other links for loose and/or damaged
parts.
. Measure and adjust the wheel alignment.
Contact a GT-R certified NISSAN dealer to
adjust the wheel alignment to the recom-
mended setting for normal driving.
Wheels and tires
.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. (
“Wheels and tires” page GTR-
17) If you do not drive under the conditions
listed in this section, see (
“Wheels and
tires” 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.
(
“Wheels and tires” 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.
Brakes
.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.
Engine and powertrain
.Check the engine, transmission, differential
and under the vehicle for oil and coolant leaks.
. 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) .
