Swiss tuner Sportech have addressed the new generation 2012 Porsche 911 with a light tuning program that will be unveiled at the 82nd edition Geneva Motor Show starting from tomorrow.
Straight to the point, Sportec says it can fit the new 911 (991) with a lowered suspension (-25 mm), 20 inch aluminium wheels wrapped in Michelin PS2 K1 tires and revised engine electronics which will enable a noticeable boost of 20 PS and 25 Nm of torque. 
Apart from that, the Sportec 2012 Porsche 911 will also feature a new exhaust system with high-flow catalytic converters, a sport air filter and a revised chassis, and as a result the German coupe’s 0 to 100 Km/h sprint time will be 4.7 seconds instead of 4.8 while its new top speed will be 6 Km/h above the 289 Km/h that can be reached by the stock model.
