hey guys, so for the past month if been hearing this mysterious knock coming from the back of the t4r. It turns out that its do to a pressure change, it only happens when going highway speeds. i can make it happen by rolling up a window. whats making the noise is my roof. since my t4r has a sunroof there isnt much support up there. so when the pressure changes in the cabin (going 60+), the roof bangs up against the 3 bars going across the roof rack. anyone had this problem? can i take those 3 bars off?
