At the conclusion of each track event, it is recommended
that a brake bleed procedure be performed to maintain
the pedal feel and stopping capability of your Brembo
High Performance brake system.
It is recommended that each track outing end with a
minimum of one cool down lap using minimal braking.
Change the differential and manual transmission fluid
after every five hours of track use. Refer to “Maintaining
Your Vehicle” for fluid levels & specifications.
If equipped with a removable lower front fascia grille, it
is recommended to remove it for track use during
warm/hot weather to improve cooling airflow to critical
powertrain and cooling system components.All SRT vehicles are track tested for 24 hours of endur-
ance, however, it is recommended that the suspension
system, brake system, prop shaft, and half shaft boots
should be inspected for wear or damage after every track
event.
Track usage results in increased operating temperatures
of the engine, transmission, clutch, driveline and brake
system. This increased operating temperature may affect
Noise Vibration Harshness (NVH) countermeasures de-
signed into your vehicle. New components may need to
be installed to return the system to the original NVH
performance.
Recommended tire pressure for track use:
•
Challenger/Charger: 40 psi hot, 32 psi front, 30 psi rear
