I'm a little disappointed that I was only able to drop 8 pounds on the driver door. Two things are true on race day. Need the windows down and can't run AC on the track pavement. This means I don't need the glass windows or it's power windows parts.
Picture before sanding and buffing the red carbon kevlar door:

Did you known the OEM door is 55lbs?

Now the passenger door doesn't need to open at all. That means it will be lighter.
