OPTIMAL PERFORMANCE
RECOMMENDATIONS
1. Minimize vehicle weight as much as possible by
removing all unessential items from the vehicle.
2. Optimize weight distribution by moving the passen-
ger seat fully rearward and the drivers seat to the
farthest back position comfortable to the driver.
3. If the vehicle is not already fully warmed up by driv-
ing it to the track, it should be warmed up before
running on the drag strip. Several miles of varied-
speed driving is sufficient to bring the full pow-
ertrain, including the transmission and axle, to
adequate temperatures. Transmission fluid tem-
perature is displayed in the instrument cluster and
in Performance Pages; reaching a minimum of
125°F (51°C) is a good indication that warm-up is
complete.

BETWEEN RUN CHECKS
Check Tire Condition
One important item is ensuring proper care of the tires.
The following is a short list of suggestions for checking
tire condition and tire care.
1. Check front and rear tire pressure.
○
Front Tires — do not exceed maximum tire infla-
tion rating.
○
Rear Tires
— depending on the outside tempera-
ture and track conditions, the operating pressure
recommendation is 18-24 psi (124–165 kPa) hot.
2. Check the tread depth to be at a safe level.
NOTE:
Tires should not be used once they reach 2/32nds
of remaining tread depth.
3. Check for uneven tire wear. Uneven tire wear could
be a result of one or more of the following:
○
Uneven tire pressure.
○
Low tire pressure.
○
High tire pressure.
○
Other issue.
NOTE:
Ensure fuel level remains above 3/8ths tank.
Wheel Lug Nut Torque
Proper lug nut torque is very important. To ensure that
the wheel is properly mounted to the vehicle use a cali-
brated torque wrench.

**Use only authorized dealer recommended lug nuts
and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to mounting
the tire and remove any corrosion or loose particles.
Tighten the lug nuts in a star pattern until each nut has
attained proper torque, verified twice each.
WARNING!
DO NOT tighten the lug nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in personal injury.
Fluids
Between runs check the following fluid levels:
•
Engine oil level.
•
Engine coolant level.
•
Brake fluid level.
WARNING!
A hot engine cooling system is dangerous. You or oth-
ers can be badly burned by hot engine coolant (anti-
freeze) or steam from your radiator. If you see or hear
steam coming from under the hood, do not open the
