Has anyone removed their factory spoiler off a gt/cs or boss Laguna stang? Is it a bolt off kind of thing or is it glued/adhered on like the regular gt? I realize there are 8 holes once removed. Ford claims that spoiler produces 90 pounds of downforce @ 130-140 mph. I would like to be able to pop it off when needed without mess/damage or swapping trunk lids. Anyone?
