Guidelines For Track Use
CAUTION!
Because of the extreme conditions encountered 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 performance in various driving situations. It is recom-
mended 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 “Fluid Capacities” in “Technical Specifications” for
further information.
• Prior to each track event, verify the front and rear brake pads have more than ½ pad thickness remaining. If the brake pads require
changing, please burnish prior to track outing at full pace.
• 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 1 cool down lap using minimal braking. • 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, driveline and brake system. This 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.
• Tire pressure: – Below 42 psi (289 kpa) hot and 33 psi (227 kpa) cold recom-
mended.
NOTE: It is recommended that you target below 42 psi (289 kpa) Hot
Tire Pressure at the conclusion of each track session. Starting at 33 psi
(227 kpa) Cold and adjusting based on ambient & 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 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 applies. Make sure the brakes are not smoking.
If they are, do another cool down lap.
3. Do not continue for more than 1 full burnishing lap after you start smelling the brakes. Do not get them smoking heavily. This will get
them too hot and affect their life negatively in future track use.
4. Allow vehicle to sit and cool in the paddock for at least 30 min. If an infrared thermal gun is available, allow rotors to cool to 200 °F
(93.3 °C) before going back out.
5. There should be a thin, ash layer when inspecting the pads installed in the caliper. Having the ash layer go more than half the thickness
of the pad material indicates too aggressive of a burnish. 6. Sometimes, a second burnish session is required. If the pads start
smelling in the next track session, reduce speed and braking decel
to burnish targets and follow steps 2-4.
7. New 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 replaced.
NOTE: Resurfacing of the rotors is not recommended, as it removes
mass from the rotor, reducing its thermal capacity. Resurfacing also
thins the rotor cheek, making it less robust and increasing the
likelihood of pulsation in further track use.
