The difference is that the F50 and CGT are roadsters rather than convertible and didn't have their structural rigidity reinforced resulting in added weight. With that being said close to zero of the CGT's performance is compromised because of the targa top.The supposed 430 Scuderia will be noticeably compromised as a performance car if turned into a convertible. Performance will be noticeably inferior to the coupe.



Any car which has an open top, especially a high performance one - be it targa or convertible - requires significant strengthening work.



Fair enough but you're forgetting that convertible and roadster, targa in particular have different architectures. The structure of the CGT is much different from the structure of 911 cabrio. Cars like the Boxster, MX5 and Z4 are built from the ground up to be performance focused hence the name roadster. The CGT is even on a higher level constructed in a way where the amount of body flex is on the same level as a car with a fixed roof, kind of like an F1 or Lemans car. The F430 has a much larger cabin and isn't engineered in the same way as the F50 and CGT. I'm sure Porsche and Ferrari tested both cars to the level that a targa top wouldn't increase drag of affect rigidity to the level that it would make a difference in notable performance.

In terms of acceleration and achievable speed the Scuderia Spider wouldn't differ too much compared with the coupe. The difference would be felt in cornering and when pushing the car hard. But like you said most of these cars end up as poser riders and probably never touch a circuit unless it's a Ferrari parade. Though there is a chance that Ferrari has worked on some magic here and defied the laws of physics like they did with the magical 599GTB.



Carrera GT is not a convertible. It's a full carbon monocoque tub chassis.

The targa roof is just a bonus, albeit a great one as it makes this car an all weather device.
