4LT GS Roadster
In 2009, Chevrolet unleashed the most powerful Corvette in the company's storied history. The ZR1 package was revived, and with it came a nasty supercharged, LS-based engine dubbed the LS9. The ZR1 Vette is more than just a C6 with a 638 hp engine: GM went all-out with carbon-fiber components throughout and a massive Brembo braking system to slow it all down from the computer-limited 205 mph top speed. It's everything a Vette enthusiast needs to eliminate those pesky Vipers and Porsche 911s that prowl the local streets and tracks. The ZR1 is also credited for bashing the production-car record at the famous Nurburgring in Germany. The record was held by a Nissan GT-R, which-allegedly-benefited from race-oriented tires and nonproduction rubber. But that's another story for another day.
