The front lip spoiler provides additional downforce over the front axle. The rear wing as well as the wing mounting was also redesigned and optimized further together with a new rear faring which comes with additional air outlet louvers. The engine lid at the rear (since its a Porsche 911) also gets better air ducting too. The extremely wide arches help hide wider front wheels which have an extra inch of width in them. The front rims are now 12inches wide running on the same 18inch diameter as previously. The fat rears are the same 18 inch diameter and 13 inch wide.
The 4.0-litre, flat six engine now delivers 455 hp at 7,800 rpm, five horsepower more than its predecessor. It still has the same 9,400rpm redline as before. The power increase comes from a revised engine management system which adapts better to different fuel grades than before, as well as a redesigned exhaust system and a modified air intake housing. The car weighs a nice 1,220kgs even with race car roll cage and other safety equipment.
The 911 GT3 RSR joins the 911 GT3 R and the 911 GT3 Cup as the top model of Porsche Motorsport's product range. The successful long distance racer – which will usually be used by their customers (like Manthey Racing) to gain massive success at the annual Nurburgring 24hours Endurance Race, can be ordered at a price of 410,000 Euro plus country-specific value added tax. All 2011 modifications are available as a kit for GT3 RSR cars from the 2010 season.
