Some customers may inquire about the possibility of installing the Camaro ZL1 1LE
carbon fiber rear spoiler (see the photo above) on a non-ZL1 1LE Camaro.
Important: The ZL1 1LE high wing rear spoiler is only designed and released to be used
on the ZL1 1LE Camaro. Installation of the ZL1 1LE high wing rear spoiler on a non-ZL1
1LE car is considered a modification to the vehicle and may negatively impact the New
Vehicle Limited Warranty.

2018 and Newer Model Years

2016-2017 Model Years

The mounting holes for the ZL1 1LE high wing spoiler
wing and the SS / ZL1 stanchion spoiler are the same.
If the customer has a car equipped with a stanchion
spoiler, the swap can be made easily as the holes for
the fasteners will line up.
Important: If the ZL1 1LE high wing is installed, the
customer should be strongly encouraged to purchase
the ZL1 1LE front splitter as well, as the extra
downforce will be needed on the front end of the vehicle
for handling.

The ZL1 1LE high wing rear spoiler uses the same
mounting holes as vehicles equipped with a stanchion
spoiler. Installation of the ZL1 1LE high wing rear
spoiler requires internal reinforcement to the decklid
due to the downforce the high wing provides. 2018
Camaro decklids are produced with the internal
reinforcement. Addition of the ZL1 1LE high wing
spoiler may cause the decklid to buckle on a 2016/2017
Camaro unless the decklid is replaced with a 2018
reinforced decklid.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
