FORD MUSTANG 2011 5.G Shelby GT500 Supplement Manual

GROUND CLEARANCE
Because of low vehicle ground clearance, use caution when
approaching curbs/curb stops from the front and rear as vehicle
damage will occur. Additionally, when crossing speed bumps or
driveway curbs, SVT recommends approaching at a 45 degree
angle to reduce the risk of vehicle damage.
WASHING YOUR SHELBY GT500
Do not drive your vehicle through an automated, commercial car
wash due to the vehicle’s low ground clearance, tire width and
track. Wash your vehicle by hand, or by using a touchless
commercial wash with no mechanical tracks on the floor. Do not
use a commercial or high pressure wand on the striped surfaces
or stripe edges.

WHEELS
Your SVT vehicle is equipped with unique wheels matched to the tires.
These wheels are more susceptible to damage due to their diameter,
width and low profile tires. To avoid damage to your wheels:
•Maintain proper tire pressure (seeTiresin this supplement).
•Do not drive your vehicle through an automated, commercial car wash
due to the vehicle’s low ground clearance, tire width and track. Wash
your vehicle by hand, or by using a touchless commercial wash with
no mechanical tracks on the floor. Do not use a commercial or high
pressure wand on the striped surfaces.
•When installing wheels, always torque lug nuts to specification with a
torque wrench.
•Inspect your wheels for damage on a regular basis. If a wheel is
damaged, replace it immediately.
•In the event that you encounter an abnormally harsh impact, inspect
the outer diameter of your wheels, both inside and out, for damage.

Operating at high speeds
Your SVT vehicle is capable of high speeds and is equipped with tires
rated for the vehicle’s maximum speed, electronically limited to 155 mph
(250 km/h). Remember to drive safely, obey all traffic laws and only
operate your SVT vehicle at high speeds at locations equipped and
designed to do so safely. Before operating your vehicle at high speeds:
•Ensure correct tire pressures (seeTiresin this supplement).
•Inspect wheels and tires for wear and damage. Replace any damaged
wheels or tires.
•Do not operate your vehicle at high speeds with more than two
passengers or while carrying cargo.
Wheel Lug Nut Torque Specifications
WARNING:When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake drum or
brake disc that contacts the wheel. Make sure that any fasteners that
attach the rotor to the hub are secured so they do not interfere with
the mounting surfaces of the wheel. Installing wheels without correct
metal-to-metal contact at the wheel mounting surfaces can cause the
wheel nuts to loosen and the wheel to come off while the vehicle is in
motion, resulting in loss of control.
Retighten the lug nuts to the specified torque at 500 miles (800 km)
after any wheel disturbance (tire rotation, changing a flat tire, wheel
removal, etc.).

Tires
Your SVT vehicle is equipped with low profile, high performance tires
that are designed to optimize the driving dynamics you expect in a SVT
vehicle. These tires are not optimized for off-road or winter (snow or
cold weather) performance, and their ride, noise and wear characteristics
are different than non-performance tires. Also, because of their lower
profile, the tires are more susceptible to damage due to potholes and
rough roads. To ensure that your tires perform as intended, it is
important that you maintain your tires properly:
•The Shelby GT500 original equipment tires are optimized for
performance in both wet and dry conditions. Ford does not
recommend using the original equipment tires when temperatures
drop to approximately 40°F (5°C) or below (depending on tire wear
and environmental conditions) or in snow/ice conditions.
•The Shelby GT500 optional P265/40-19 front, P285/35-20 rear
directional tires were designed for track use and may exhibit
significantly reduced tread life and increased tire noise compared to
the standard equipment tires under normal driving conditions.
Increasing the front camber settings beyond the factory settings may
further accelerate tread wear and induce tire noise.
•Do not use tire chainson the original wheels and tires of your
vehicle. The use of any type of tire chain on these tires may damage
your vehicle.
•For tire pressures, see the placard located on the B-pillar inside the
driver’s door.

•Always maintain your tire pressures according to the tire information
placard on the driver’s door jamb, using an accurate gauge.
•Tire pressures are specified “cold” and should be checked after the
vehicle has been parked for at least 3 hours. Do not reduce pressure
of warm tires.
•Check your tire pressure often to maintain it properly. Tire pressure
can diminish over time and fluctuate with temperature.
•Do not overload your vehicle. Maximum vehicle and axle weights are
listed on the tire information placard.
•Extra caution should be taken when operating the vehicle near its
maximum load, including assuring proper tire pressure and reducing
speeds.
•Extra caution should be taken when operating on rough roads to avoid
impacts that could cause tire damage.
•In the event that you encounter an abnormally harsh impact, inspect
your tires for damage.
•Inspect your tires for damage on a regular basis. If a tire is damaged,
replace it immediately.
•Proper suspension alignment is critical for maximum performance and
optimal tire wear. If you notice uneven tire wear, have your alignment
checked.
•Rotate tires as recommended in the following sectionTire rotation.
•When replacing tires, the only way to ensure original performance is
to use the original equipment tire. If a different tire is used, it should
be the same size, speed rating and load rating and be replaced as a set
of four. Never mix tire brands.
WARNING:For vehicles equipped with optional performance
package tires (P265/40-19 front, P285/35-20 rear), only replace
wheels and tires with the EXACT original brand, size and construction
tire with which your vehicle was originally equipped. Use of any other
wheel/tire combinations, even with identical size ratings, may result in
insufficient running clearances, tire rubbing and eventual puncture.
Loss of tire pressure could lead to a loss of vehicle control leading to
serious injury or death.

Winter driving
The original equipment tires on your SVT vehicle are designed for
maximum performance in dry and wet summer conditions. They are not
designed for winter use on ice or snow and cannot be used with snow
chains. If you will be operating your vehicle in these conditions, winter
or all-season tires must be used.
•Use winter tires with a “V” speed rating and a 93 load index or higher
for all models. You may also use P255/45R-18 winter tires with a “V”
speed rating and a 93 load index and 18 in. wheels from the
2007-2010 model year Shelby GT500. Using these wheels will ensure
adequate brake and suspension clearance.
•Do not use a winter tire with less than a “V” speed rating, and even
with clear, dry driving conditions do not operate your vehicle above
posted speed limits while using winter tires. Never perform high speed
driving with winter tires.
Please call the Ford Performance Info Center at 1-800-FORD-SVT
(367-3788) for specific winter tire recommendations.
Tire rotation
Because your vehicle is equipped with unique larger tires on the rear
wheels, you can only rotate the tires side to side. You must not rotate
tires in a crisscross pattern or front to rear. If you notice that the tires
wear unevenly, have them checked.
Note:The optional performance package tires (P265/40-19 front,
P285/35-20 rear) are directional. Tire rotation is not recommended for
directional tires.
The tires on your Shelby GT500 should be rotated every 5,000 miles
(8,000 km). This will help your tires wear more evenly, providing better
tire performance and longer tire life.

•Tire rotation (front tires at the
top of the diagram)
Sometimes irregular tire wear can be corrected by rotating the tires.
Note:If your tires show uneven wear, ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.

WRECKER TOWING
If you need to have your vehicle towed, contact your roadside assistance
center or a professional towing service.
It is recommended that your vehicle be towed with a wheel lift and
dollies or with flatbed equipment. When towing with a flatbed, 4x4
blocks must be used when loading/unloading your vehicle. Do not tow
with a slingbelt. Ford Motor Company has not approved a slingbelt
towing procedure.
Note:If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
