@compFI, most Cobras in Europe ran hard-tops back in the day. We here in the US, would run what European drivers would call "short courses" 2-3 miles a lap, with short straightaways, and more turns.
LeMans, Spa, Hockenheim, etc., were long courses, a lot higher avg. speed per lap, so aerodynamics were much more in play over the pond.
Daytona coupes were built to run in Europe, with the exception being the Daytona & Sebring (High avg. speeds) tracks here.
Hope this helps. Cheers Tom.
