Specially-engineered tabs eliminate the wind buffeting caused by driving at speed with the windows down.
This is a well engineered, quality manufactured, and easily installed piece that does the job. No more whumping cabin noise!
Installed last week ahead of a three day event at MidOhio. Simple, clean install. Took about 10 min.
Radical reduction in buffeting at high speed (140mph plus). Smooths out the airflow.
Expensive, but the results make it a good investment.
Got to Watkins Glen last weekend for PCA drivers ed. The wind buffeting was completely eliminated even at 130-140 mph speed with both windows down. Absolutely satisfied with the purchase.
