German tuner creates the TechArt GTStreet RS based on the most powerful series 911 around.

German tuner TechArt wants to squeeze in one more 997 tuning job before they move onto the new 991 Porsche 911.

And this one is the ultimate 997 - the Porsche 911 GT2 RS which TechArt has re-christened the GTStreet RS.

The power kit created by the tuner dials output up by 100 PS on the GT2 RS to 530 kW (720 PS) and 900 Nm (664 lb-ft) torque. That makes the GTStreet RS do the 0 to 100 km/h sprint in just 3.3 seconds while top speed clocks in at 352 km/h (219 mph).

The body kit consists of a front apron with both a fixed carbon splitter and an adjustable one made of polyurethane-RIM, additional air vents, carbon-fiber rear spoiler, rear apron with integrated diffuser as well as the carbon fiber air wings.

For the ride is a hydraulic noselift system offering a height adjustment of 10 mm as well as the 20-inch Formula Race lightweight forged rims with central locking.

The interior finish includes touches in carbon-fiber as well as the aluminum pedals.
