2021 CORVETTE Z51
TRACK PREPARATION
Corvette Stingray with the Z51 Performance Package has been designed and engineered to be a
world-class sports car for the track. But before unleashing its acceleration, cornering and braking
capability, there are several key procedures and steps that must be taken. This guide includes an
overview of requirements and recommendations. These are general guidelines and are not all en-
compassing. Use good judgment at all times to determine the appropriate adjustments and speeds
for the track configuration and environmental conditions.
The Owner’s Manual contains important restrictions, precautions and safety procedures. Always
read and follow all of the instructions in the vehicle Owners Manual.
DANGER: High-performance features are intended for use only on closed tracks by experienced and
qualified drivers and should not be used on public roads. High-speed driving, aggressive cornering,
hard braking, and other high-performance driving can be dangerous. Improper driver inputs for the
conditions may result in loss of control of the vehicle, which could injure or kill you or others. Always
drive safely.
Note: This supplement is for Corvette Stingray with Z51 Performance Package. Vehicles without the Z51 package should not be used for track events
and competitive driving. Track events or competitive driving may affect the vehicle warranty. See the warranty manual before using the vehicle for
track events or other competitive driving.
