TRACK USE - MACH 1
Operating at High Speeds and
Track Days
Your vehicle is capable of sustained high
speeds and track day driving.
Before operating your vehicle at high
speeds:
•
Verify your tires have the correct
pressures.
• Inspect wheels and tires for wear and
damage. Replace any damaged wheels
and tires.
• Check and set lug nut torque. See
Technical Specifications (page 334).
• Verify fluid levels for oil, coolant, brake
and hydraulic fluid. See
Capacities
and Specifications (page 335).
• Change the engine oil and replace the
engine oil filter prior to use on the track.
Change the engine oil and filter again
after every four hours of track time.
Maintain the engine oil level at or near
the max mark on the engine oil dipstick.
See
Engine Oil Check (page 261).
• Replace the brake fluid with fresh
Motorcraft/Ford DOT 4 LV High
Performance Brake Fluid or other DOT
compliant fluid with a dry boiling point
greater than
500°F (260°C) from a
sealed container. Do not use silicone
or DOT 5 brake fluids. •
If you are operating your Mach 1 on a
drag strip, use drag strip selectable
drive mode in addition to using line lock
and launch control to provide a specific
set-up tuned for the quickest straight
line elapsed times.
• If you are operating your Mach 1 on a
road course, use sport or track
selectable drive modes to provide a
specific set-up tuned for optimal shift
and suspension set-up that is tuned
towards handling prowess on closed
course surfaces.
After operating your vehicle at high speeds
or track day driving, do the following:
• Set the tire pressure to the proper
specification.
• Check and set the lug nut torque. See
Technical Specifications
(page 334).
• Check all fluid levels.
• Refer to the track maintenance interval
chart. See
Normal Scheduled
Maintenance (page 444).
• Check the front and rear wheel
bearings for abnormal wear.
• Inspect brake caliper dust boots for
abnormal wear.

advanced technology cannot defy the
laws of physics. It is always possible to

road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.

Adjustable Camber Front Strut
Top Mounts (vehicles with
Optional Handling Package)
Your vehicle has adjustable strut mounts
which you can use to adjust the camber of
your vehicle before and after a track event
to the specifications listed in the Road
Course Alignment Recommendations table
previously shown.
Note: After your track day is complete,
return your car to the street alignment and
tire pressures. Note:
The adjustable camber front strut
mounts are fitted with three set screws that
must be removed before camber can be
adjusted. If you cannot adjust the camber,
please see your authorized dealer or call
800– 367–3788 for more details to remove
the set screws. Aerodynamics
(If Equipped)
Rear Gurney Flap The rear Gurney flap must be removed
for on-road driving.
Your vehicle may include a removable
Gurney flap in the luggage compartment.
The Gurney flap greatly enhances high
speed stability and performance on the
track. It is recommended that you use the
Gurney flap at all tracks featuring high
speed corners and can be used at any track
regardless of cornering speeds.
You could benefit from the removal Gurney
flap to improve low speed balance on
smaller tracks with maximum cornering
speeds below
70 mph (112 km/h). We
recommend that you attach the Gurney
flap for all track events and carefully
assess both the vehicle's condition and
your capability before removal.

TRACK USE
Appropriately change the engine oil for
racing and other track events:
•
2.3L: Prior to the track event, drain the
engine oil, replace the oil filter and
change the engine oil to 5W-50. After
the track event, drain the engine oil,
replace the oil filter and refill the engine
oil with 5W-30. See Capacities and
Specifications (page 343).
• 5.0L: Prior to the track event, drain the
engine oil, replace the oil filter and
change the engine oil to 5W-30. After
the track event, drain the engine oil,
replace the oil filter and refill the engine
oil with 5W-20.
See Capacities and
Specifications (page 343).
Regularly check the engine oil level during
the event. Maintain the engine oil level at
or near the max mark on the engine oil
dipstick. See Engine Oil Check (page 261).

(If Equipped)
Adjustable Rear Wing
The rear wing generates aerodynamic
down-force at speeds greater than 50 mph
(80 km/h)
.
Regularly inspect the rear wing panel and
attachment points for damage or
looseness.
You can adjust the wing using the hole
pattern at the top of the stanchion.
Moving the wing up increases rear down
force and overall understeer. Moving the
wing down decreases the rear down force
and overall understeer.

WAXING
Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.
When washing and waxing, park your
vehicle in a shaded area out of direct
sunlight. Always wash your vehicle before
applying wax.
•
Use a quality wax that does not contain
abrasives.
• Follow the manufacturer ’s instructions
to apply and remove the wax.
• Apply a small amount of wax in a
back-and-forth motion, not in circles.
• Do not allow wax to come in contact
with any non-body (low-gloss black)
colored trim. The wax will discolor or
stain the parts over time.
•Roof racks.
• Bumpers.
• Grained door handles.
• Side moldings.
• Mirror housings.
• Windshield cowl area.
• Do not apply wax to glass areas.
• After waxing, your car's paint should
feel smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE -
MACH 1
Note: Do not allow water or cleaning
solutions to contact the exposed air filter
element. Cover the air filter assembly and
avoid spraying water at it. CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
When washing:
•
Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold
water to avoid cracking the engine
block or other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.
Note: If your vehicle has an engine cover
remove the cover before application of
Motorcraft Engine Shampoo and Degreaser.
Immediately rinse away any over spray.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
Note: Do not allow water or cleaning
solutions to contact the exposed air filter
element. Cover the air filter assembly and
avoid spraying water at it.

Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
•
Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected
during storage such as mice or squirrel
nests.
• Check the exhaust for any foreign
material that may have collected
during storage.
• Check tire pressures and set tire
inflation per the Tire Label.
• Check brake pedal operation. Drive
your vehicle 15 ft (4.5 m) back and
forth to remove rust build-up.
• Check fluid levels (including coolant,
oil and gas) to make sure there are no
leaks, and fluids are at recommended
levels.
• If you remove the battery, clean the
battery cable ends and check for
damage.
Contact an authorized dealer if you have
any concerns or issues.
CLEANING THE CONVERTIBLE
TOP
(IF EQUIPPED)
Remove lint with a lint roller or a vacuum
with a soft bristle brush.
For cloth and vinyl tops, wash with an
approved high-quality convertible top
cleaner and protectant.
Note: Do not use stiff bristle brushes,
abrasive materials or household cleaning
products. Note:
High-pressure water may cause
water leaks and possible seal damage to
the convertible top.
Note: Do not fold the convertible top when
it is wet.
Note: Avoid hot wax on vinyl materials
during car washes.
BODY STYLING KITS
(IF EQUIPPED)
The distance between the underside of
your vehicle and the ground is less than
that of other models. Drive with extreme
care to avoid damage to your vehicle.
