Avus have re-mapped a GTRIt's not hard to understand why matte-black is one of our favorite shades for the almighty Nissan GT-R that has been upgraded by Germany's Avus Performance. Using the limited production GT-R Black Edition that leaves the factory in a dark metal gray with a black and red interior as a base, the tuner covered the entire body of the high-performance coupe in a flat black wrap while the 20-inch alloys that are combined with wheel spacers have been finished in a glossy black color.Performance modifications include a retuned ECU and a sportier exhaust system that does away with the two cats and the middle silencer helping the 3.8-liter twin-turbo V6 engine to produce a total output of 580 horsepower and 700Nm or 516.3 lb-ft of torque, up from 485HP and 588Nm.Avus Performance also lowers the GT-R's ride height through different coilovers offering the car an even more menacing stance.According to the German tuner, the matte black wrap will cost you €2,499; the coilovers €1,299; the ECU tune €1,899; the exhaust upgrade €998; the painted 20-inch alloy wheels €999 and the wheel spacers €349.how much torque??
