Swiss Missile: Sportec SP750 Porsche 997 GT2

Porsche enthusiasts will undoubtedly count the 997-generation 911 GT2 as one of the most extreme supercars ever to roll out of Stuttgart – right up there with the 959 and the Carrera GT. But where there's speed, there's always room for more speed, and the Swiss aren't about to stay neutral on this matter. Switzerland-based Sportec has just released its latest offering: the SP750. The tuning firm is known for producing seriously fast Porsches – including the 997 Turbo-based SP580 and the record-chasing SPR1 and SP600M Cayenne – and has put some serious effort into carrying on this legacy with the new SP750.

Modifications to the GT2 – already very blitzschnell in its own right – are available in four increments, starting with the 600-hp Stage 1 and topping out with the full-on 750-hp Stage 4 kit, which includes new turbos, a revised ECU, titanium con-rods, a free-flowing exhaust and new camshafts, air filter and clutch. To control all that extra power, Sportec is also offering an upgraded brake kit with six-pot calipers and 350-380mm discs, plus a retuned suspension complemented by a revised aero kit and 20-inch rims. We'd hope the huge Swiss flag on the roof, which has become a hallmark of Sportec's creations, is optional. While it may protect the car from aerial bombardment, the planes would actually have to catch the car in the first place.
