Thinking about buying the AutoTecknic Aero replacement sidemirrors (link below) to prevent the wind buffeting but my car came with the carbon fiber side mirror caps.
I know there are 8 dollar pieces you can get to prevent it but I like the "aggressive" look it gives the car.

Selling my OEM carbon fiber mirror caps. They came with the car and were taken off after 2k miles. Perfect condition, no chips or delaminating.
