About ALUMINUM SPOILER for my mx3

[1QuiCkSiLvErMx3]

i just recently install an aluminum gt spoiler in my car, the guy who install my wing told me that theres a possibility that my wing could ripp out the whole entire back window of the car due to the hight of the wing and also a big risk if Im driving more than 80 miles/hour.....? ist true?
