THe softtop as a whole (motors fabric, etc everypeice added together) weighs 65lbs I have my old one sitting in my bedrooom
My hard top (Mugen CF replica) weighs about 35lbs with my real glass rear window...
SO really the weight savings is only about 30lbs.. Most Americans could go on a diet and save more than that in a few months

 

Oem hardtop is 44 pounds I believe.

 

Wow I contemplated this but for 21 lbs is not worth it to me. Especially since it takes approx. 4 hrs to remove the soft top.
