Coupe side window issues

[BigShooter]

The shop I'm having finishing my car has brought up some good issues about the rear portion of the side windows. Please feel free to share ideas or address concerns as I ponder different ways of handling that part of my car.
NOTE: I'm in TX and thus will be a heavy user of AC; so I must have a good seal in that area for hot days (most days!).

1. If I use the flared windows to suck air into the cockpit - this is obviously good only on non-AC use days. Given that I could do what some have done and fit plexiglass inserts in to prevent that air from getting in - however, this will create a lot of positive air pressure and probably knock those inserts out.
2. I could fabricate slots in the bodywork so as to insert glass or plexiglass inserts to block the air and handle the positive pressure, then would need to cut vents/slots in the back of the curved plexiglass piece so the wind/force doesn't tear them off the car.
3. I could NOT install the curved piece at all and instead create a nice permanent glass piece flush with the main window, and then fill in and smooth out the body where the grooves for the curved window piece are
4. The existing main plexiglass race car window with small slide opening: I'm not a huge fan of these, but also don't want to pony up $3500 for the aftermarket power glass windows. Will probably just go with the FFR supplied race car windows as I've heard the car is very loud so people tend to keep the windows closed all the way. Question: do the FFR windows work OK? Do they leak a lot of air in? (or rain on wet days?)
5. Any other side window/rear side window applications that y'all have used that you like?

I have the flaired windows on my coupe with the block off windows in place to keep air out. I also do this for AC and sound.
I just had the car to 147MPH and no issues with them being ripped off car. It does take some trial and error to make it all fit good but worth the effort.

I too have the side scoops and fill panels on my Coupe. I haven't gone as fast as Rsnake (!!) but at 110+ mph and 4 seasons of driving, no sign of any issues with pressure or whatever. I expanded on some ideas in other build threads and made the fill panels easily removable and seal better than how FFR supplies them. Shown in my build thread here: https://thefactoryfiveforum.com/showthread.php?26630-Edwardb%92s-Gen-3-Type-65-Coyote-Coupe-59-Build-5-000-Mile-Report&p=375735&viewfull=1#post375735. But for heat and sound, only had the side windows and fill panels out once. We don't find the small openings a big deal. Just part of the character of the car. Not air or water tight, but good enough and get the job done. The roll-up window mod is nice, I guess, but also didn't want to spend the money and based on experience, they'd be closed all the time anyway. If I were to build another, I'd maybe consider door poppers so not have to reach through the side windows to open the doors. But also not a real big deal once you're used to it. Putting a flat piece in the scoop area and leaving the scoop off is a definite option. But even though they're not functional with the fill panels in place, I still prefer the look of them.

Thank you - very helpful to know. I also like the looks of the flared piece and with these bits of encouragement think I'll keep them in the build!
