For those of you who have gone to the extent of removing your soft top and are looking for more weight savings:
Have you considered chopping the windshield? I am considering doing this, but frankly would prefer to see the results on someone else's car first... hehe. My idea is to chop the side supports for the windshield, then trim the actual glass windshield, refinish all cut edges to make them look nice again, and remove the little triangle window section from each door. The car would look a lot more like this:

Total savings should be between 20 and 30 pounds, depending on just how much these items weigh. I personally would reinstall the rear view mirror on the dash, so let's call it 20 pounds and a whole different look for the Miata!
What do you guys think?
