Tonight while opening my rear door after heading to my local race strip. I heard a distinct "Pop" from under the car just while opeing the door (not closing). I tested that on all four doors. It had just occurred at tonight. Any advice on what it could be? Does it have anything to with reach 115mph?

I am getting the same thing. Its as if you're breaking the seal of a compressed cabbin. I get it but just brushed it off as 'one of those things'
