countermeasures designed into your vehicle. New com-
ponents may need to be installed to return the system to
the original NVH performance.
• Tire pressure:
• 40psi (276kpa) hot, recommend 32psi (221kpa) front,
30psi (207 kpa) rear cold
NOTE: It is recommended that you target 40psi (276kpa) Hot
Tire Pressure at the conclusion of each track session. Starting at
32psi (221kpa) Front & 30psi (207 kpa) Rear Cold and adjust-
ing 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 compo-
nents are installed:
1. Use one track session to burnish brakes by driving at
75% speed. Brake at approximately 0.60-0.80g max with-
out 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 indi-
cates 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
step 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.
