2015 - 2017 corvette Z06 Wiker bill Installation

During the installation of the rear wicker bills that are fastened on the rear spoiler, some technicians may revert to the use of power tools to tighten the fasteners.

The use of power tools should not be used due to the fact that this could lead to damage to the fasteners and/or the spoiler.

When installing the wicker bills onto the vehicle, it is recommended to hand start the fasteners before using the correct hand tools to torque the fasteners to the proper torque specifications.

Damage to the fasteners or the spoiler should not be submitted under warranty as the parts are dealer installed components during the pre-delivery process.
