Some 2016-2017 Camaro convertible models may have a noticeable wind noise condition at the rear quarter window area. The wind noise may be due to a misalignment between the front side window and the rear quarter window on either side of the vehicle.
Confirm the location of the noise by taping off the gap between the front side window and the rear quarter window and drive the vehicle. If the noise is eliminated, the gap between the rear quarter glass and the front side window should be adjusted.
There are three measurements to check and adjust to correctly set the gap — two adjustments to the vertical gap between the two windows and one adjustment to the height of the rear quarter glass.
Vertical Gap Adjustment
The first two measurements are related to the vertical gap between the front side window and the rear quarter window. This gap is V-shaped by design. When the folding top is lowered, the gap between the two windows is 12 mm wide at the top and 10 mm wide at the bottom.
When adjusting the vertical gap, the folding top must be in the stowed or lowered position. After adjustment, when the top is closed and latched, the rear quarter glass window will be pushed forward slightly. The result will be an even 10 mm gap between the two windows from top to bottom. (Fig. 6)

Glass Height Adjustment
The third adjustment to the height of the rear quarter glass will change the location of the rear quarter glass (Fig. 7, #1) so that it sits 4 mm higher (Fig. 7, #3) than the front side window glass. (Fig. 7, #2)

Once the quarter window is adjusted, compare the two panes of glass at the base. They should be flush with each other (inboard vs. outboard). If the difference between the front and rear windows is more than 1.5 mm, or if there is a visible gap that can be seen between the seals, the rear quarter glass will need to be adjusted further.
First, loosen the forward nut by the rear quarter glass. (Fig. 8) Gently push out on the base of the quarter glass to decrease the noticeable gap. Once the gap is within 1.5 mm of the front side glass, tighten the nut to 80 inch pounds (9Nm) of torque. Do not push the glass out too far.

Test drive the vehicle to determine if the noise has been eliminated or if more adjustment is needed.
Window Channel
If the glass adjustments have been made and wind noise is still present, inspect for the presence of a foam piece in the rear of the window channel. (Fig. 9) If the foam is missing, insert a foam piece into the window channel. If the foam is in the window channel, installing a slightly larger foam piece will put more outward tension on the window seal, helping to reduce any lingering wind noise.
