   Sinopec circuit features long straights followed with violent sharp brakings, fast turns that require perfect car balance and many slow and medium speed corners . The most violent braking point is at kurve 8 where cars brake from320 km/hand seventh gear to only 68  and first gear loosing 2649 KW of kinetic energy . Lower 2011 entry speed in tight kurves 3 , 4 , 5 , 6 , 7 , 8 , 9  indicates the worse grip level provided by Pirelli tyres compared to Bridgestone . On the contrary higher 2011 entry speed in medium kurve 1 reveals the higher amount of aerodynamic downforce generated by 2011 cars body permitting a faster travel through the corner .

Data : Brembo
