competitive driving. Excessive tire
wear is not covered under the
vehicle warranty.
The racing and competitive driving
wheel alignment settings should be
set as described here.
To achieve the track alignment
specified settings: 1. The upper control arm to body washers on all four corners will
need to be moved from
between the body and the
control arm and relocated
between the head of the bolt
and the control arm.
2. Adjust the lower control arm cam bolt position to achieve
the following specifications.
Front (per corner)
. Caster: +8.0 degrees
. Camber: -3.0 degrees
. Toe (total): 0.1 degrees toe in Rear (per corner)
.
Caster: 0 degrees
. Camber: -2.5 degrees
. Toe (total): 0.1 degrees toe in
. Thrust Angle: 0 degrees
After track use, reinstall washers
between the body and the control
arms. Reset to factory alignment
settings.
General Information
If reduced performance is
experienced during track events or
competitive driving, turning off the
A/C will help to improve engine
performance.
Maintain a mixture of 40%
DEX-COOL coolant and 60% clean,
drinkable water to optimize engine
performance.

Use this rotation pattern if the
vehicle has different size tires
on the front and rear.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. See
Tire Pressure0253 and
Vehicle Load Limits 0160.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation 0256. Check that all wheel nuts are
properly tightened. See
“Wheel
Nut Torque” underCapacities
and Specifications 0299.
{Warning
Rust or dirt on a wheel, or on
the parts to which it is
fastened, can make wheel
nuts become loose after time.
The wheel could come off and
cause a crash. When
changing a wheel, remove any
rust or dirt from places where
the wheel attaches to the
vehicle. In an emergency, a
cloth or a paper towel can be
used; however, use a scraper
or wire brush later to remove
all rust or dirt.
Lightly coat the inner diameter of
the wheel hub opening with
wheel bearing grease after a
wheel change or tire rotation to
prevent corrosion or rust buildup. Do not get grease on
the flat wheel mounting surface
or on the wheel nuts or bolts.
When It Is Time for New
Tires
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
Treadwear indicators are one way to
tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)
