First, you are about to know how the wind noise accrued during the time of your driving. You have to understand the mounting system of car roof boxes then you will realize why there is wind noise exists.
In general, car roof boxes are mounted on car roof bars(rack systems), and different cars need different rack systems. The Fit Kit and the tower are the two most essential components of the mounting system. If you have a flat roof, you may need to purchase a fit kit to support the tower. If you need to buy a fit kit, you have to contact your car dealer for advice because a fit kit is not a universal fit product. If you know what type of fit kit you need, you can check Ebay or Amazon search results for Fit kit.
Besides, the towers are universal fit, so you can pick one set and mount them on the fit kits. The towers can help you to hold the bars in positions on the roof of your car.

The round crossbar is standing in the middle of these three options. The aero rack bar is quiet while you are driving, but it is expensive.
After a secure and accurate installation of a rack system, you can attach your car rooftop carrier to the roof of your vehicle with two types of components: t-track adapters or U-bolts.
