The Audi R8 Spyder 5.2 FSI Quattro in its standard version delivers 525 hp of power and 390 lb-ft of torque. There are people who consider this to be enough and are satisfied by the present setup though there are others who think otherwise. Sports Wheels has such a line of thinking and they have come up with a tuning package that has resulted in the car deliver a whooping 600 horsepower.
There are two upgrade offers from the tuner. One is where the engine delivers 565 hp and 560 Nm of torque instead of the 525 hp and 530 Nm rating of the standard engine. The other has the power lifted to 600 hp and torque to 580 Nm. This has been made possible by addition of ironman muffler along with software to adjust this with the ESD.
Wheels also have been changed in the package to 20 inch with 235/30-20 Conti Sport Contact tires for the front and 11×20 inch wheels with 305/25-20 tires for the back. A crank angle screw thread of the model 3 HLS4 has also been added in the tuning package.
