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. Ensure 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.
IMPORTANT TIRE INFORMATION

care must be taken when operating and maintaining your vehicle.

Tires
Your Boss302 is equipped with low profile, high performance tires that
are designed to optimize the car’s driving dynamics. 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 Boss302 and Boss302 with Laguna Seca Package original
equipment tires are optimized for maximum steering and handling
performance. Ford does not recommend using these tires in cold
temperatures of approximately 40°F (5°C) and below (depending on
tire, surface and weather conditions). See your Ford dealer for
recommended tires in these conditions.

TRACK PREPARATION
The Boss302 and Boss302 Laguna Seca edition have been rigorously
proven out on race tracks. Below are recommendations for optimizing
your Boss302 for a track day event.
•For optimal performance, premium fuel is recommended.
•
Change brake fluid to Super DOT 4 to improve track performance of
braking system (WSS-M6C65-A2), Ford part number (YS4Z-19542-AA).
•Install Ford Racing front brake cooling kit (M-2004-MB) to improve
brake cooling (standard on Laguna Seca edition).
•Remove rear brake dust shields to improve brake cooling.
•Install Ford Racing transmission cooling scoop (M-5025-MBR) to
improve transmission cooling (standard on Laguna Seca edition).
•During extended track sessions in extreme temperatures or
conditions, your Boss 302 may require additional engine cooling
actions. If the water temperature warning light illuminates, return to
the paddock and let the vehicle return to normal operating
temperature while idling before turning the engine off. Prior to the
next session, remove your Boss 302’s upper grille from the front
fascia. This will allow more cooling air to the radiator and allow the
car to run extended sessions in extreme heat. Visit fordracing.com for
additional parts to further enhance the powertrain cooling on your
Boss 302.
•For extended track use, Ford recommends installing a rear differential
cooler to improve rear axle cooling.
•Remove vertical rear tire spoilers at rear edge of rocker moldings.
•The Ford Racing front splitter kit (M-16601-MB, standard on Laguna
Seca edition) can be installed to improve high-speed vehicle stability
and handling. If the Ford Racing front splitter kit will be installed on a
Boss 302 without the Laguna Seca package, Ford recommends
installing the Laguna Seca edition rear spoiler in place of the standard
rear spoiler to maintain aerodynamic balance. This front splitter is
intended for race track use only and is not legal for on-street driving.
It may degrade crash performance and void the vehicle warranty. The
front splitter must be installed by the customer.
