Dodge Challenger SRT 392 2015 Operating Information Manual page 142

that your vehicle operates in SPORT or TRACK
modes during the track event.
Prior to each track event/day:
• Verify all fluids are at the correct levels. Refer
to "Maintaining Your Vehicle" for fluid levels &
specifications.
• Verify the front and rear brake pads have
more than ½ the original pad thickness re-
maining. 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 stop-
ping capability of your Brembo High Perfor-
mance 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 transmis-
sion 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 cool-
ing airflow to critical powertrain and cooling
system components.
All SRT vehicles are track tested for 24 hours of
endurance, 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 tem-
peratures of the engine, transmission, clutch,
driveline and brake system. This increased op-
erating temperature may affect Noise Vibration
Harshness (NVH) countermeasures designed
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 components are in-
stalled:
1. Utilize one track session to burnish brakes
by driving at 75% speed. Brake at approxi-
mately 0.60 – 0.80g Max without ABS inter-
vention.
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 application. Make sure
the brakes are not smoking. If they are, do
another cool down lap.
3. Do not continue for more than one full bur-
nishing 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 infra-
red thermal gun is available, allow the rotors
to cool to 200° F (93.3° C) before going back
out.
