TRACK PREPARATION
The Boss302 and Boss302 Laguna Secaedition 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 Secaedition).
•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 Secaedition).
•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 the round fog light delete covers from the upper
grille. This wi ll 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.
•The Ford Racing front splitter kit (M-16601P-MBA, standard on
Laguna Secaedition) 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 Secapackage, Ford
recommends installing the Laguna Secaedition rear spoiler in place
of the standard rear spoiler to maintain aerodynamic balance. The
unique lower grille from the Laguna Secaedition should also be
installed to accommodate the splitter support rods. 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.
