GUIDELINES FOR TRACK USE

Overview

NOTE:
Because of the extreme conditions encoun-
tered during track use, any damage or wear
associated with track use is not covered by
warranty.
If your SRT vehicle is equipped with Drive

Modes, they will alter the vehicle's perfor-
mance in various driving situations. It is
recommended that your vehicle operates in
SPORT or TRACK mode during the track
event.
Prior to each track event/day, verify all fluids

are at the correct levels.
Prior to each track event, verify the front and

rear brake pads have more than ½ pad thick-
ness remaining. If the brake pads require
changing, please burnish prior to track outing
at full pace.
NOTE:
Use of DOT 4 brake fluid is suggested for
extended track usage due to increased thermal
capacity.
At the conclusion of each track event, it is

recommended that a brake bleed procedure
is performed to maintain the pedal feel and
stopping capability of your Brembo High
Performance brake system.
It is recommended that each track outing

should end with a minimum of one cool down
lap using minimal braking.
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 endurance. However, it is recommended
that suspension system, brake system, prop
shaft, and ½ shaft boots should be checked
for wear or damage after every track event.
Track usage results in increased operating

temperatures of the engine, transmission,
clutch – if equipped, driveline and brake
system. This may affect Noise, Vibration, and
Harshness (NVH) countermeasures designed
into your vehicle. New components may need
to be installed to return the system to the
original NVH performance.
Tire pressure:

40 psi (276 kpa) hot, recommend 32 psi

(221 kpa) front, 30psi (207 kpa) rear
cold
NOTE:
It is recommended that you target 40 psi (276 kpa)
Hot Tire Pressure at the conclusion of each track
session. Starting at 32 psi (221k pa) Front and
30 psi (207 kpa) Rear Cold, and adjusting based on
ambient and track conditions, is recommended.
Tire pressure can be monitored via the instrument
cluster display and can assist with adjustments.

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
installed:
1. Use one track session to burnish brakes by
driving at 75% speed. Brake at approxi-
mately 0.60-0.80 g 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 cooldown
