i just bought and installed mugen style visors from ebay they are excellent have had no problems the car is more quiet on the highway now and even with the windows slightly down barely any noise they are the best exterior mod i have done especially for 50 bucks

 

i love mine too.. although one of them pull off during some aggressive washing lol

 

I've had cheap fake Mugen Vent-visors on my GD3 for over 2 years now and they are as great in every respect that kevbluedog say they are.. It is cool that the work better at deflecting air at high speeds than at low speeds.

 

If these help with the wind noise and such then I think I made need to get some. I do, however, fear they will come flying off at 90+ mph and impale a random motorcyclist as would be my luck...

 

I had to lift one off an reset it when installing them and that one began to come loose.. I caught in in time so it didn't fly off and I replaced the double sided tape with some new 3M tape I got at either Lowe's or Auto Zone... They are doing fine even in 100+ temperatures and 100+ MPH.
