Window separation at high speeds
Any one had their windows separate from their car at high speeds? If so what did you do to fix it? Looked around couldn't find anything, maybe im bad at searching. This is a question for a friend not me... sorry if this is in the wrong section. 99 coupe

Adjusting the window tip in might help - here is the procedure:
Problem: Excessive Air Noise from Windows
Solution: Window Tip-in adjustment
Tools Required
#6 Inverted TORX® Socket
Position the window fully up.
Remove the large access plug from under the front of the door.
Loosen the window regulator front channel mounting nut.
Remove the reflector from the trim panel.
Loosen the jack screw jam nut.
Adjust tip in with the jack screw.
Turn the jack screw clockwise to tip the window outward.
Turn the jack screw counterclockwise to tip the window inward.
One turn of the screw equals approximately 1 N•m (0.04 in) change at the top of the window.
Tighten the jack screw jam nut.
Lower the window.
Tighten the window regulator channel front mounting nut.
Raise the window and check the alignment.
Install the access plug under the front of the door.
Install the reflector in the door trim panel.
Also, you might want to adjust the blow-out clip on the targa top. Here's a write up on the procedure:
There are two ways to adjust the blowout clip:
1. Measure distance between window glass and inner edge of clip. It should be less than 2 mm. If it’s more than 2 mm, lower window, protect clip with some tape and hammer/bend the clip carefully with a plastic hammer. Slowly lift up window and check distance between clip and glass. Open door slowly and close door slowly to check for enough distance between glass and clip. DO NOT slam door unless you are sure there is enough space between clip and glass! Do not bend the clip to much as this will disturb the rubber from the weatherstrip! Test drive and adjust again if there’s sill noise.
2. The clip is fixed with a Phillips head screw to the roof. You need to lift of the weatherstripping a bit where the clip sits and loose that screw. Now you can move the clip in and outwards to get the correct distance between window glass and clip. When clip is adjusted to less than 2mm glass/clip distance tighten screw and check for glass/clip clearance by carefully opening and closing the door. Again: be very carefully not to break the glass if the clip is too tight!
Test drive and adjust again if necessary. When all is fixed, glue the weatherstrip again to the roof and drive without noise up to 150 mph.
In 99% of these cases, this will solve the problem. Most of the time IT IS NOT a bad adjusted window! The clip keeps the window from being sucked out at higher speed when the pressure inside of the car is higher than outside of the car. If the clip is not set right, the pressure will suck the window out and, in the worst case, the glass will stay outside of the clip. In that case water will enter the inside of the car!
