"While Audi&amp;#039;s first-ever factory appearance at SEMA featured an autonomous TT that drove itself up Pikes Peak, the real star of its stand was the 2010 Audi R8 Custom Spyder by ST\u0101SIS Engineering, an Audi tuning specialist based at Summit Point Raceway in West Virginia, not far from Audi&amp;#039;s U.S. headquarters in Herdon, Virginia.   The tuner has developed a Signature Series for the R8, which features primarily mechanical and suspension upgrades to the otherwise stock-looking Spyder. Chief among these changes is a supercharger package on the standard 5.2-liter V-10 engine, which raises output from 525 to 710 bhp and torque from 391 to 523 lb.-ft., thanks to 7.5 psi of boost. ST\u0101SIS Engineering claims a 0\u201360 time of 3.1 seconds, 0.6 sec. quicker than stock. Also helping increase engine power is a lightweight, larger-diameter stainless-steel exhaust system.   The car retains its power top and standard cabin features. Beneath the skin, however, the Challenge Extreme Package also includes remote-reservoir \u00D6hlins shocks, stiffer anti-roll bars and new springs that significantly lower the vehicle&amp;#039;s ride height. The car is equipped with 20-in. forged alloy wheels and larger Alcon disc brakes. The R8 Spyder is shod with Michelin Pilot Sport PS2 tires, measuring 255/30 in front and 325/25 in the rear. The company backs its work with a 4-year/50,000-mile warranty and sells the package through 56 dealers nationally. "^^<http://www.w3.org/2001/XMLSchema#string>
