I was hoping these would cut back on the buffeting with the top down, but windows up. It did not seem to make much of a difference. The installation was simple.

What most other reviewers said about effectiveness, to wit: buffeting gone, fit/finish very good (one poster mentioned a gap but check your stock triangles before removal and you'll see the oem's have the same gap), worth it. For early 991's , installation isn't hard but it's not plug/play like on newer 911's. Getting the four plastic trip pieces and four bolts off is a breeze after you've done it once. Removing and reinstalling the door is also simple once you've done it once.
My only caveat is to make sure you fully connect the blue multiprong door plug before reinstalling the door. There's a little purple plastic hinge that kind of ensures it's fully pushed in, but the first time I did it none of my door/window functions worked. Took door off again and saw that I hadn't pushed the blue plug in all the way. Once it's in, you'll know it by how far in it goes.
I could now install two AWE's diffusers in under 10 mins per side. If you're in the Bay Area and want to avoid the learning curve on an early 991.1 (i.e., door removal required), drop by and I'll help you out! I'm in Redwood City (Emerald Hills), firstname.lastname@example.org.

Completely worth the price, they almost completely remove all buffeting at any speed when the passenger window is closed and the driver's window is open. Unless you have a very early 981, the install takes 5-10 minutes per side, and if you do it right, anyone will think they are OEM. Too bad Porsche doesn't install them from the factory.

I know what your thinking $80 for two pieces of plastic, but I can tell you they really do work. If you want to get rid of the wind buffeting and drive with one or two windows open at any speed this is the only way to do it. I have a 991.1 and before the wind diffusers I needed to open the sunroof with the windows open. They fit well also.

Pretty straightforward easy installation and they do lessen the wind buffeting at speed...but way over priced for what they are. Should be no more than $50

I was a bit skeptical. However, it works well. Easy install. It should be a factory OEM option. When I track my 991.2 GT3 they require windows down. The buffeting was intolerable until now. Highly recommend.

Installation easy. Passenger side fits good but not as well as the driver's side. Cuts out wind issues especially at HPDE events.

Plastic feels flimsy compared to OEM. Fit was good on driver side, but there is a bigger gap on the passenger side.
Installation is very easy.
It does reduce buffeting at highway speeds. But, when the widows are up I can now hear a whistling noise. It's not loud but still audible. TBH I'm not sure I'll keep these on or not.

A little pricey for two pieces of plastic but they work. Took just a small amount of finish work to get them to fit perfectly. Had to remove the door panel to install but not difficult and worth the extra effort.

I received the items in a reasonable amount of time and was accurately filled. Thanks Suncoast. Installation was straight forward, however the company should have included the interior trim tool which would be inexpensive. In the instructions it stated there maybe a gap once installed due to different applications, however the gap was very uneven and varied from side to side. Because of this it doesn't look like an OEM piece. I haven't been able to test its effectiveness but assume it'll work just fine based on the previous reviews.
