The new GT2 RS also features plenty of advanced technology to accompany all that power. The upgrades include a racing chassis with rear-axle steering and a modified stability control system, as well as a lighter weight titanium exhaust system and extensive use of magnesium and carbon fiber. Expect the 2018 Prosche 911 GT2 RS to hit our shoes in 2018, with prices start at $294,250.
