Ok we know the interior is different,color scheme, the bubble roof...but deeper into the car, what are the differences?

 

I don't think much else. You mentioned the different interior which I think includes Adaptive Sport Seats as standard with the woven leather material. It of course has a ducktail and different exhaust tips. Different Fuchs look wheels. I think that is about it.

 

Rick - you always make someone else do the work. Google Porsche Sport Classic and there's lots of info including this from Wikipedia:

911 Sport Classic (2010-)
It is a limited (250 units- all sold) version of 911 Carrera S coupé, inspired by the 1973 Carrera RS 2.7. The engine is rated 408 PS (300 kW; 402 hp) via newly developed resonance intake manifold with 6 vacuum-controlled switching flaps. It includes 6-speed manual transmission, double-dome roof, 44 mm (1.7 in) wider rear body, SportDesign front apron with spoiler lip and the rear spoiler fixed in position (from 1973 Carrera RS 2.7), PCCB Porsche Ceramic Composite Brakes, 20 mm (0.8 in) lower PASM sports suspension, mechanical rear axle differential, 19-inch wheels with black rim spokes, Porsche Exclusive woven leather seats and door panels, dashboard with Espresso Nature natural leather upholstery, Sport Classic Grey body colour.

The vehicle was unveiled in 2009 Frankfurt Auto Show.[22]

Production vehicles went on sale in January 2010. European model had base MSRP of €169,300 (before tax).[23]

Top Gear featured the car during seasons 15 second episode on July 4, 2010.

 

jh if we all follow your way of thinking this forum should not exist because everything is in the net, yes? you shouldnt be here because your contributions and queries are all in the net, yes? ok now maybe we can get on with the conversation. thank you by the way for all the info.
i was hoping someone knew if there was a difference with the drivetrain like spring rates torsion bar thickness, pasm software between the gts and the sc…i would have thought that porsche did not just get the sports classic and turned it into the gts…there should be somehting more special with the sports classic. someone said the ride was different.. maybe someone has more info. if jh can still provide the comparo, much appreciate it

 

Performance, Mechanically and engine wise.... NO difference! Different exhaust sound and tips on Classic, but that's it as far as mechanically. I have often thought that I would be a little annoyed as a Sport Classic owner knowing that Porsche charged $100,000 premium over a GTS for a nicer interior, ducktail spoiler, and other miscellaneous aesthetics...

add the ducktail spoiler, sport classic chin spoiler and side skirts to a GTS and you virtually have 98% Sport Classic aesthetics with 100% performance and mechanical bits....
