Something, something, average day for a mustang driver.

Honestly, I'm shocked it could get going that fast.

Assuming you are asking for installation advice, please consider hiring a professional. I am no stranger to diy projects and thought I could adjust and fix mine on my own and ended up snapping the spring. I tried to figure out what to replace it with but ended up calling out a professional. The door now works far better than it ever did and I know I could not have done as good a job.
