Eliminate the wind buffeting that is a common issue that plagues modern Porsches with our new air deflectors. We all have been the victim of the brain rattling noise that occurs when your window is down during driving speeds. This phenomenon is the product of air entering and exiting through the same window and results in that low frequency rumble we all know. Rennline's anti wind buffeting deflectors redirect the air away from the open window that would otherwise cause this terrible noise.
