KresoF1:
Christian,
This is old AMS article and 991.1 Turbo S Cab is in comparison.
Btw, 650S Spider Hockenheim time is 1:08,7min with Corsas.
With a time of 1:09.8 minutes, the Porsche 911 Turbo S Cabrio lags well behind the best time of its hard-top relative (1:08.7 min) in spite of the Dunlop Sport Maxx racing tyres.
Maybe the 650s should have Trofeo tyres for equality but then the gap would be larger
