Convertibles are usually heavier than coupes due to the additional chassis stiffening added to the floor and lower corners. Usually, the additional stiffening weighs more than the roof which was deleted. I do not know anything about whatever additional stiffening Porsche placed into Targa chassis'. It does not surprise me to hear reports of Targas having structural integrity. Porsche seriously knew how to build cars. That said, I don't think it takes a Hans Stuck to notice the difference between a Targa and a Coupe. Finally, I have heard some report a preference for Targas on the track. It seems counterintuitive, but I have heard this preference.
