1Add the coolant type originally equipped in your vehicle.2Rear axle lubricants do not need to be checked or changed unless a leak is suspected, service is
required, the axle assembly has been submerged in water, or when subjecting your car to
high-speed and/or competition use. The axle lubricant and friction modifier should be changed any
time the rear axle has been submerged in water. The axle lubricant and friction modifier should
also be changed after the initial (first) hour of high-speed operation or if the vehicle is subjected to
track or competition conditions; thereafter changing the axle lubricant and friction modifier every
12 hours (under 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.

•For track sessions, it is recommended to run 41 psi (283 kPa) hot for
the OEM tires, front and rear.
•Depending on track temperature, ambient temperature and driving
style, you may need to reduce the starting tire pressure by as
much as 4 psi (27 kPa).
•The starting pressure may be lower in the rear tires relative to the
front tires to achieve 41 psi (283 kPa) hot.
•Reset tire pressures to placard recommended pressures before
leaving the track.
•For improved track performance, Ford recommends
,
available through Ford Racing. See your local Ford dealer or go to
http://www.trackey.ford.com for more information (M-14204-MBTKA).
•
Your Boss302 is equipped from the factory with Brembo 4-piston front
calipers and unique, high-performance rear brake pads that will provide
excellent performance under normal driving conditions. Ford recommends
the following bedding procedure for race track driving be followed.
Note:Restore the vehicle to factory specifications prior to driving on
public roads.
Brake burnishing procedure for race track driving
If the vehicle has to be driven on a track (racing) or in severe driving
conditions, the following steps must be performed on a closed course,
not on public roads:
•
Burnish: 30 burnish stops at 60-0 mph (96-0 km/h), 0.4g deceleration,
one mile (1.6 km) between stops. If the vehicle has more than 200 miles
(322 km) on the brakes, skip this step and proceed to the Fade stops.
•Fade: 20 fade stops, at 65-0 mph (105-0 km/h), 0.85g deceleration or
just below ABS activity, no dwell between stops
•Cool down: Minimum of five mile (8 km) cool down route, if on public
roads (no brakes) run at 60 mph (96 km/h)
•Recovery: 30 recovery stops at 60-0 mph (96-0 km/h), 0.4 g
deceleration, one mile (1.6 km) between stops
•Cool down: Minimum of five mile (8 km) cool down route, if on public
roads (no brakes) run at 60 mph (96 km/h)

Damper adjustment recommendations:
•Boss302 - Set all four dampers to position (5) for all tracks.
•Boss302 Laguna Seca edition - Set front dampers to position (5) and
set the rear dampers to position (3), (4) or (5) depending on how
smooth the track is or how much curbing the driver likes to use.
•On a rough track, set the rear dampers to position (3).
•On a smooth track with aggressive apex curbs, set the rear
dampers to position (4), but only if the driver uses those curbs.
•On a smooth track with mild FIA-type apex curbs, set the rear
dampers to position (5).
•If the turn-in portions of the track are rough, reduce the front damper
setting by one position until the Boss302 turns in on those rough
portions.
•If the rear of the car is skipping over bumps during corner exit so that
the driver has to reduce throttle input, reduce the rear damper setting
by one position until the driver can apply appropriate throttle.

WARRANTY COVERAGE
The Boss302 carries the same warranty as other Ford Mustang models.
This information is covered in its entirety in the Ford Motor Company
Warranty Guide.
The three unique Laguna Seca Package high performance parts (front
splitter, front brake cooling kit, and transmission cooling scoop) are
intended for track use and have no warranty coverage.
Warranty service for the Boss302 can be obtained at any Ford dealer
nationwide.
Ford does not recommend modifying or racing Ford vehicles, as they are
designed and built to be driven as delivered from the factory. The Ford
Motor Company Warranty Guide discusses vehicle usage and the
installation of aftermarket parts and their effect on warranty coverage.
Please see the Warranty Guide for complete information.
In the event the vehicle is intended for track use, and the loss of
warranty coverage is not of concern, the following vehicle durability
modification is required:
•Ford recommends that you change your axle lubricant and
friction modifier after the initial (first) hour of high-speed
operation or if the vehicle is subjected to track or competition
conditions; thereafter changing the axle lubricant and friction
modifier every 12 hours (under these conditions).
•Ford recommends you change your oil and filter after your
vehicle is subjected to track and/or competition conditions.
Additionally, perform multi-point inspection and the maintenance
outlined in the 150,000 mile (240,000 km) normal maintenance schedule
of thescheduled maintenance informationafter track use. Refer to
the vehicle service manual for removal and installation procedures.
Replace with Genuine Ford and Motorcraftservice parts as needed.
These modifications may not necessarily protect your engine from
damage in competition conditions. Subjecting your vehicle to competition
conditions even with these proposed modifications may render repairs
non-reimbursable under the warranty.
