the first time you take it off can be a little bit of a pain because of the plastic retainers described above, but other than that its easy, especially with air tools, 1st time may take 30-45 minutes, after that maybe 20 min.
i drive mine everyday with it off, it takes getting used to but its not as bad as some people describe, just dont forget its off and try to take an offramp at 130mph

its also fun to launch and feel/see the front of the car come up
