Okay, I feel it would be remiss to point out that the 50 lbs (if the sunroof weighs the same as the 993 sunroof cited earlier) is not a net gain. It is offset by the removal of whatever roof material the sunroof replaces. I will have to admit though, that I have no idea how thick or heavy the removed section of steel (?) would be.

Anyone have a guess/feel for what the removed section of roof might weigh?
