The current 997TT NBR lap should be 7.42 (10s slower than 997GT2). But it is only 7.52. The new GT-R lap is probably 7.43-5, which makes sense as it is not that much heavier than the 997TT and tested cars were probably a little special... The facelift TT should be 7.38-40 thus settling all this performance discussion between the two cars. But it won't be. The TT is loosing massive ground vs all its competitors (Z06 GT-R LP560 F430scud).

Porsche better sort this out asap, for all you know the Panamera TT might be faster
