Guidelines For Race Track Use Of Your SRT
WARNING!
Always drive carefully within your capabilities.
Never drive in a reckless or dangerous manner,
which can jeopardize the user ’s safety or the safety of
others. Only a safe, attentive, and skillful driver can
prevent accidents. NOTE:
Due to the extreme conditions encountered dur-
ing track use, any damage or wear associated with track
use is not covered by the manufacturer ’s warranty.
If your SRT vehicle is equipped with Drive Modes, they
will alter the vehicle’s performance in various driving
situations. It is recommended that your vehicle operates
in SPORT or TRACK modes during the track event.
Prior to each track event/day:
• Verify allfluids are at the correct levels. Refer to
“Maintaining Your Vehicle” for fluid levels & specifi-
cations.
• Verify the front and rear brake pads have more than ½
the original pad thickness remaining. If the brake pads
require changing, please burnish prior to track outing
at full pace. Refer to “Track Burnishing Your Brakes.”

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
cold

Track Burnishing Your Brakes
To avoid “green lining fade” during track use, the brake
pads and rotors must have a thermal burnish for factory
installed components or when new brake friction com-
ponents are installed:
1. Utilize one track session to burnish brakes by drivingat 75% speed. Brake at approximately 0.60 – 0.80g Max
without ABS intervention.
2. Lap the track in this manner until you start smelling the brakes. Continue for another ½ lap at speed, then
do a two lap cool down with minimal brake applica-
tion. Make sure the brakes are not smoking. If they are,
do another cool down lap.
3. Do not continue for more than one full burnishing lap after you start smelling the brakes. Do not get them
smoking heavily. This will get them too hot and will
negatively affect their life in future track use. 4. Allow the vehicle to sit and cool in the paddock for at
least 30 minutes. If an infrared thermal gun is avail-
able, allow the rotors to cool to 200° F (93.3° C) before
going back out.
5. There should be a thin, ashy layer when inspecting the pads installed in the caliper. If the ash layer is more
than ½ the thickness of the brake pad material, this is
an indication of too aggressive of a burnish.
6. Sometimes, a second burnish session is required. If the brake pads start smelling in the next track session,
reduce speed and braking deceleration to burnish
targets and follow steps 2 through 4.
7. New brake pads installed on old rotors still need to be burnished. New rotors installed with old pads should
be burnished at the track, or street driven for 300 city
miles, to develop an adequate lining transfer layer on
the rotor surface prior to track use.

8. Rotors that pulsate during track use should be re-placed. Resurfacing of the rotors is not recommended,
as it removes mass from the rotor, reducing its thermal
capacity. Resurfacing also thins the rotor cheek, mak-
ing it less robust and increasing the likelihood of
pulsation in further track use.
SRT Performance Pages
Performance Pages is an application that provides a
display for performance indicators, as received from the
Instrument Cluster, that will help you gain familiarity
with the capabilities of your SRT vehicle in real-time.
To access the SRT Performance Pages, press the “SRT &
Apps” button on the touchscreen, then press the “SRT
Performance” button on the touchscreen, or press “SRT
Pages” in the top left of the touchscreen while in Drive
Modes. Press the desired button on the touchscreen to
access that specific Performance Page.
WARNING!
Measurement of vehicle statistics with the SRT Per-
formance Pages is intended for off-highway or off-
road use only and should not be done on any public
roadways. It is recommended that these features be
used in a controlled environment and within the
limits of the law. The capabilities of the vehicle as
measured by the Performance Pages must never be
exploited in a reckless or dangerous manner, which
can jeopardize the user ’s safety or the safety of
others. Only a safe, attentive, and skillful driver can
prevent accidents.
