Eliminate wind buffeting and elevate the exterior styling of your BMW G90 or G99 M5 with AutoTecknic's Dry Carbon Side Mirror Wind Deflectors — precision-engineered for drivers who demand improved cabin comfort and a motorsport-inspired aesthetic.
The Problem: Wind Buffeting at Speed
Wind buffeting is a well-known issue when driving with the windows down at speed, creating uncomfortable turbulence inside the cabin. On a high-performance vehicle like the G90/G99 M5, this becomes especially pronounced during spirited driving or track use — undermining the driving experience the car was built to deliver.
The Solution: Precision Airflow Management
AutoTecknic's wind deflectors are purpose-designed to redirect airflow away from the cabin, significantly reducing turbulence — while sharpening the aggressive profile of your M5 with a factory-integrated carbon fiber accent that looks like it belongs there.
Premium Dry Carbon Fiber Construction
Each wind deflector is manufactured using multiple layers of pre-impregnated (pre-preg) carbon fiber, bonded and autoclave-cured under controlled heat and pressure for optimal structural integrity.
This premium process delivers:
Each unit is finished with a high-gloss automotive clear coat for superior UV resistance and lasting shine — maintaining that showroom look mile after mile.
Precision Development & Fitment
Developed using in-house 3D scan data from our own G-series shop vehicle, every contour is matched to the factory mirror bases for a seamless, OEM-quality fit. No guesswork, no gaps — just a clean integration that complements the M5's existing design language.
Simple, Non-Invasive Installation
No drilling. No cutting. No permanent modification. These wind deflectors mount securely using included 3M VHB automotive-grade double-sided tape for a clean, professional install that's also fully reversible.
