Porsche 911 GT3 RSR
2011 Porsche GT3 RSR hits the new new motorsport season with a number of modifications. It features improvement of the aerodynamics at the front and rear, changes to the suspension kinematics and to the engine.
The vehicle is powered by 4.0 liter flat-six with 455HP (335 kW) at 7800RPM. The upgrades include an engine management system which adapts even better to different fuel grades, as well as a redesigned exhaust system and a modified air intake housing. However, the monster still revs all the way up to 9400RPM, where nothing else matters.
At the front, the new GT3 RSR has a new front lip and wider front rims - 11J or 12J. At the rear, the position and the shape of the wing are optimised. The rear lid was also redesigned for optimised air ducting. Taken directly from the latest 911 road-legal cars - LEDs are present, too.
2011 Porsche GT3 RSR is priced at 410 000 EURO.
