lower braking efforts for three minutes
of driving. Allow for increased braking
distances due to reduced brake output.
2. After Step 1, increase speed and braking
effort for the next six minutes of
lapping, gradually ending up at 90%
effort. Continue to allow for increased
braking distance due to reduced brake
output.
3. Cool the brakes by lapping with minimal
light braking for six minutes.
Brake Cooling Kit
Prior to any track event, high speed driving
event, or competitive driving, the following
should be completed:
.
Ensure all brake cooling parts are
correctly and securely installed.
.
Install the rear lower control arm cooling
ducts per the instructions below also
included with the kit. After any track
event or competitive driving, remove the
rear lower control arm cooling ducts.
These parts are for track use only.
Removing the ducts helps prevent debris
from being channeled into the rear brakes
during regular use of the vehicle.
.

the ducts.

Shock Spring Seat Adjustment
The front shocks, on vehicles without
hydraulic front lift and rear shocks, have
threaded spring seats that allow adjustment
of the preload on the coil springs. The
vehicle corner weights can be adjusted for
track use. If the vehicle trim height is
modified, it should be returned to normal
trim height before street use.
