I have a 2001 Boxter where I did some work to it which required me to take off the back bumper. Now, when I put my spoiler up, the right lifter comes up higher than the left one. When I put my spoiler down (manually) the right lifter doesn't go down at all. I also noticed that the left lifter is too close to my trunk door. It actually touches it. How can it be crooket?
