Overview

A must-have for any 992 owner. The sub-woofer-like booming when you roll the windows down is mitigated by these simple add-ons — good for track use or just enjoying the car with the windows open.

The deflectors attach easily with 3M VHB double-sided tape. Each is produced from multiple pieces of pre-preg carbon bonded together, then clear coated in an automotive high-gloss finish.

Scan data taken in-house ensured the units contour properly to the mirror bases, and CFD confirmed they don't add unnecessary drag or disrupt other aerodynamic devices downstream.

The Engineering

The buffeting comes from airflow around the A-pillar attaching and detaching while the windows are down, building pressure waves in the cabin. These deflectors ensure the airflow detaches cleanly as it passes the windows, stopping the problem at its source.
